7. The Intent of the Challenge: The team must build a Structure made entirely of materials chosen from a list (see Section A.3). A “Bill of Materials” (BOM) used to build the Structure will be created and included in the team’s paperwork. The team must test the Structure’s strength at the tournament by placing weights on it and by subjecting it to Ram impacts at a marked corner of the Pressure Board that will cause a twisting force. The team must create a Story which includes an unexpected event or twist. Additionally, the team must build a prop or costume using only all the same materials used in the Structure.

8. In addition, the team must present TWO creations called “Team Choice Elements” that show off their interests, skills, areas of strength, and talents. The team may create anything they wish for Team Choice Elements including props, music, technical gadgets, costumes, physical actions etc.

9. a. The minimum dimensions of the Presentation Site will be 16ft x 16ft (4.88m x 4.88m). In most cases, this area will not be marked on the floor. When possible, the tournament may provide a larger Presentation Site. The team may use all of the Presentation space available at their site, but they must be prepared to present in the minimum area specified. The team should keep in mind that the weights, Structure Tester, and Ram will occupy a portion of the Presentation Site. b. The team must not move the Structure Tester from its location. c. A single 3-prong AC electrical outlet will be provided at least to the edge of the Presentation Site.

16. A. Central Challenge - Section 1 Intent of the Challenge: The team must build a Structure made entirely of materials chosen from a list (see Section A.3). A “Bill of Materials” (BOM) used to build the Structure will be created and included in the team’s paperwork. The team must test the Structure’s strength at the tournament by placing weights on it and by subjecting it to Ram impacts at a marked corner of the Pressure Board that will cause a twisting force. The team must create a Story which includes an unexpected event or twist. Additionally, the team must build a prop or costume using only all the same materials used in the Structure.

17. Questions for Appraiser Training Challenge E: Twist-O-Rama 1. The team arrives in the Check-In area with a Structure, but no Bill of Materials or material samples. What should the Check-In Appraisers do? 2. The team arrives in the Check-In area with a Structure, but the BOM and/or the materials samples do not match the materials used in the Structure. What should the Check-In Appraisers do? 3. The team arrives in the Check-In area with a Structure, BOM, and materials samples. However, one, more, or even all of the materials listed on the BOM are not directly recognizable in the composition of the Structure. What should the Check-In Appraisers do?

18. Questions for Appraiser Training Challenge E: Twist-O-Rama 1. The Check-In Appraisers should review with the team the Challenge requirements (A.3.b.ii) that state a Bill of Materials and materials samples must be provided. They should further explain the points at risk in not fulfilling the requirement. If time permits, they should allow the team to create the BOM and produce material samples. If the team fails to provide an accurate BOM and valid material samples, they should receive a 0 for C.3. 2. There are a couple of possibilities here. If the Structure is eligible for weight score, the Check-In Appraisers should point out the discrepancy, explain the points at risk, and allow the team to create the Bill of Materials and produce material samples. However, if the Structure does not pass, the Appraisers should give the team the opportunity to make changes to the Structure. The Appraisers should remind the team that in order to get the 10 points for the BOM and materials samples, the modified Structure may require a modified BOM.

19. Questions for Appraiser Training Challenge E: Twist-O-Rama 3. The Check-In Appraisers should ask the team how they built the Structure and why the materials are not recognizable. If the team has a plausible explanation, the Structure should be passed and marked eligible for weight score. The Appraisers may need to mark the “Yes – Structure to be returned to Check-In” box in order to take a better look after the Presentation.

20. Questions for Appraiser Training Challenge E: Twist-O-Rama 4. An Elementary Level team arrives in the Check-In area with a Structure that only contains two different materials, e.g. only Bamboo and Glue. What should the Check-In Appraisers do? 5. A Secondary Level team arrives in the Check-In area with a Structure that contains five different materials, but two of the materials are tiny pieces merely added to the Structure and they do nothing to help the Structure support weight. What should the Check-In Appraisers do? 6. The team arrives in the Prep Area without a Bill of Materials. What should the Prep Area Appraiser do? 7. In reviewing the Tournament Data Form, Page 2 Part THREE 2b, the Prep Area Appraiser really does not understand what the surprise or twist is supposed to be. What should the Prep Area Appraiser do?

21. Questions for Appraiser Training Challenge E: Twist-O-Rama 4. The Check-In Appraisers should review with the team the Challenge requirements (A.3.a.i) that state Elementary Level teams must use at least three Materials. The team should retreat to attempt to modify their Structure to meet this requirement. When they return, the Check-In process starts again from the start. 5. Assuming there are no other issues, the Structure should be passed. The Challenge does not require any Material to be weight bearing or appear in any minimum quantity.

22. Questions for Appraiser Training Challenge E: Twist-O-Rama 6. The Challenge (A.7.b) requires that one prop or costume must be built of the same material types as the Structure. In addition, the team is required to create a BOM that lists the material types used in the Structure. However, the Challenge does not state that the team must provide a copy of the BOM at the Prep Area. The Prep Area Appraiser will have to evaluate the validity of the materials used in the prop or costume by observation. 7. The Prep Area Appraiser should ask the team for an explanation. The purpose of the Tournament Data Form is to provide guidance to the Appraisers. If the Prep Area Appraiser does not understand the team’s TDF, there is a high probability that the scoring Appraisers will not understand either. Have the team attempt to improve their TDF while still in the Prep Area.

23. A. Central Challenge – Section 2 2. Designing and Building the Structure: a.The team must design and build a Structure, made only of materials chosen from a specific list (see Section A.3), that will be tested at the tournament. Teams are encouraged to build and test many structures before they come to the tournament. b.The team must design the Structure so that they can place it on the Structure Tester at the tournament for testing. The team will test how much weight the Structure can hold by stacking a Pressure Board and weights on it (Section D.4.a shows a diagram of a Structure Tester), while at the same time subjecting it to off-center torque and twist-inducing impacts. c.Team members must do all tooling and/or shaping of the materials chosen.

24. A. Central Challenge – Section 2 d.The team must not use any type of technology that designs, creates or aids in the testing of the Structure based on input of the Challenge specifications such as Computer Aided Design (CAD) or Structural Analysis Systems. The team must make any Jig(s) (see definition) used to construct the Structure.

Twist Ties – Paper or plastic wrapped wire, 4in (100mm) or less in length: Paper or plastic wrapped lengths of wire available in supermarkets and used as a bag closure. iii. Natural wood and products made from natural wood CANNOT be used in the Structure or in the scored prop/costume ( see A.7.b). Natural wood is a substance found under the bark of any type of tree. Products made from natural wood such as plywood, Masonite, and fiberboard or chipboard are also NOT acceptable

28. A. Central Challenge – Section 3 iv. The team may join materials together in any fashion. v. Teams must not melt any materials except Glue for use in their Structure. vi. Incidental marks – pencil or ink – are allowed. b. The team must create a Bill of Materials (BOM) used, and samples of those materials must be provided. i. Appraisers will inspect the materials used in the Structure during Structure Check-In (See D.2) and make sure that they correspond to those listed in the BOM. If necessary, the Appraisers will examine the materials again after the team tests the Structure. ii. The team will receive points for providing a Bill of Materials and samples of the materials. c. The team will be asked to describe their Structure and tell why they chose the various materials. The team’s design will be appraised on how creatively the multiple materials were included and used.

29. A. Central Challenge – Section 3 d. Weight of the Structure: The total weight of the Structure must not exceed 175 grams. e. Height of the Structure: The height of the Structure must be at least 7.5in (19.1cm) and no more than 9.0in (22.9cm). f.The Structure must be a single unit. Multiple free-standing pieces placed on the Structure Tester will not meet the Challenge requirements. g.The Structure must fit on the Structure Tester. (See D.4) i.An opening that can easily accept a circular column with an outside diameter of 2in (5.1cm) MUST run the entire height of the Structure. This ensures that the Structure will fit easily around the Safety Pole of the Structure Tester, but not through the hole in the Pressure Board. ii.When the Structure sits on the Tester Base, it must fit completely within the Tester Base and around the Safety Pole. h.The only places the Structure may make contact with the Structure Tester are the top surface of the Tester Base, the bottom surface of the Pressure Board, and the Safety Pole.

30. A. Central Challenge – Section 4 4.Weight Held Measurement Procedure: a.After the Presentation time begins, the team will place the Structure over the Safety Pole so that the Structure rests only on the Tester Base. The Structure may touch the Safety Pole. b.The team may start Weight Placement at any time once the Presentation time begins. (See D.4 for Weight Placement details.) c.The team begins Weight Placement by placing the Pressure Board on the Structure. d.After the Pressure Board is placed, the team must deliver an impact to the corner of the Pressure Board using the Ram (see Section A.5). The team will receive a 50 pound Bonus Card if their Structure successfully survives the Ram impact. This card is placed by a team member on top of the Pressure Board. e. Each time a total of 45 or more pounds of weight is successfully added to the Tester weight stack, the team must deliver another impact to the marked corner of the Pressure Board using the Ram. The team will receive a 50 pound Bonus Card each time their Structure successfully survives a Ram impact. This card is placed by a team member on top of the weight stack. f. After each Ram impact, the 45 pound “count” begins again. No weight amount “carries over” from prior loading. Example: After the Pressure Board is placed, a Ram impact is required. Next, if 45 or more pounds are loaded on the Tester (one 45 pound weight, or two 25 pound weights, or a 25 pound and two 10 pound weights, etc.) another Ram impact is required. When 45 or more pounds is again loaded after this impact, another Ram impact is required.

31. Questions for Appraiser Training Challenge E: Twist-O-Rama 8. Since the last Ram Impact Bonus, the team has placed 10, 5, 10, and 5 pound weights. The team then places a 45 pound weight, for an incremental addition of 75 pounds. What should the Weight Placement Appraiser do? 9. Since the last Ram Impact Bonus, the team has placed 10, 5, 10, 5, and 10 pound weights. The team then moves the Ram from the Ram Box and begins to line up the Ram with the Pressure Board. What should the Weight Placement Appraiser do?

32. Questions for Appraiser Training Challenge E: Twist-O-Rama 8. The Weight Placement Appraiser should announce that a Ram Impact is required. The Challenge (A.5.b) states that a Ram Impact is required once the team has placed 45 pounds or more on the Tester weight stack. The 30 pounds previously placed did not reach the 45 pound threshold, but adding the 45 pound weight certainly did. 9. The Challenge (A.5.b) states that the Weight Placement Appraiser determines when a Ram Impact is required. Also, the Challenge (D.7.b) states that the Weight Placement Appraisers will inform the team when a Ram Impact is required. Therefore, the team should not attempt a Ram Impact unless the Weight Placement Appraiser has announced “Ram Impact required.” In this case, the team has not reached the 45 pound threshold and should not yet be attempting a Ram Impact. The Weight Placement Appraiser is not obligated to stop the team from performing a Ram Impact, but cannot grant a Bonus even if the Ram Impact is otherwise successful.

33. A. Central Challenge – Section 4 g. Once a bonus for a successful Ram Impact has been granted and the team has placed the Bonus Card on the Tester weight stack, no weights under the Bonus Card may be removed. Weights added after the latest Bonus Card may be removed. h.After the Presentation time ends, the Weight Placement Appraiser will note the weight that the Structure held. This is called the Official Weight Held, which includes the weights and the Pressure Board. Only the weights that are physically on the Pressure Board when Weight Placement ends are included in the Official Weight Held. i.The Weight Placement Appraiser will also total the number of successfully survived Ram impacts. These are indicated by Weight Bonus Cards received by the team (See A.4.d&e). The number of Bonus Cards multiplied by 50 will equal the Total Bonus Weight (TBW). j.The Weight Held Ratio (WHR) is the Official Weight Held in pounds plus the Total Bonus Weight in pounds divided by the Structure’s weight in grams (measured to the nearest tenth of a gram), rounded to two decimal places. Weight Held Ratio = (Official Weight Held in pounds + Total Bonus Weight in pounds) ÷ the Structure’s weight in grams Example: If the Official Weight Held is 195 pounds and the Total Bonus Weight is 200 pounds (4 survived Ram impacts) and the Structure’s weight is 52.3 grams, the Weight Held Ratio is 7.55 (WHR = (195 + 200) ÷ 52.3 = 7.55).

34. A. Central Challenge – Section 5 5. The Ram: The Tournament Director will provide the Ram for use at the tournament. (See Section D.4 for a diagram of the Ram.)The Team does NOT bring, and cannot use, its own Ram at the tournament. For the purpose of this Challenge, a Ram Impact is the act of striking a marked corner of the Pressure Board with the Ram. Each Ram Impact will be delivered by a team member. The Ram has been designed to deliver a calibrated impact to the Pressure Board when operated as directed. When a Ram Impact is required, it will be performed in the following manner: a. The Ram starts in the Ram Box-- a taped area at least 3ft (90cm) from the Tester. b. After the Weight Placement Appraiser determines that the team has successfully placed 45 pounds or more on the Tester weight stack, the team will remove the Ram from the Ram Box and place it next to the Tester. c. While the Ram is outside of the Ram Box, Weight Placement stops. During this time, only team members operating the Ram may be inside the Safety Line – a line taped 10in (25 cm) from the edge of all sides of the Structure Tester on the floor of the Presentation Site. The Safety Line around the Structure Tester is viewed as an imaginary plane that extends vertically from the floor to the ceiling. d. The team will place the Ram so that while at rest, its impacting face squarely contacts (touches) a marked corner (team choice) of the Pressure Board.

35. Questions for Appraiser Training Challenge E: Twist-O-Rama 10. The Weight Placement Appraiser has announced to the team that a Ram Impact is required. While one team member is moving the Ram from the Ram Box to the Structure Tester, another team member grabs another weight and is moving toward the weight stack. What should the Weight Placement Appraiser do? 11. The Weight Placement Appraiser has announced to the team that a Ram Impact is required. The team then moves the Ram from the Ram Box and places it next to the Pressure Board. The Weight Placement Appraiser notices that the team is using a different corner than previous impacts. What should the Weight Placement Appraiser do?

36. Questions for Appraiser Training Challenge E: Twist-O-Rama 10. As long as the team member with the weight remains beyond the Safety Line, the Weight Placement Appraiser should say nothing. However, if the team member crosses the line, the Weight Placement Appraiser must remind the team of the safety rules and stop the action until the team member backs away from the Safety Line.

37. Questions for Appraiser Training Challenge E: Twist-O-Rama 11. The Challenge (A.5.h.i) states the Weight Placement Appraiser is to determine that Ram procedures were followed before granting a Bonus. The Challenge does not say that it is up to the Weight Placement Appraiser to coach the team if they are not following the Ram procedures. Therefore, the Weight Placement Appraiser should do nothing to stop the team. After the Ram Impact, the Weight Placement Appraiser should tell the team why they are not granted a Bonus, and have them retry the Ram Impact.

38. A. Central Challenge – Section 5 e.The team may not alternate corners for subsequent impacts, and must use the same corner face for each impact. Each of the eight corners of the Crusher Board will have a unique identification label to assist the Team in meeting this requirement. f.The team will then pull back the Ram until it rests against the Ram stop. The team will then release the Ram. g.The Ram may not be touched by anything or anyone after it is released, until it stops moving. h.When the Weight Placement Appraiser determines that the Ram has completed an appropriate impact, that four (4) seconds have elapsed, and that none of the requirements listed in D.7 for Weight Placement to end are met, then a 50 pound Bonus will be granted. The Weight Placement Appraiser will inform the team of the Bonus grant, and give a Bonus Card to the team for placement by a team member on the weight stack. The decision of the Weight Placement Appraiser is final. i.If the Weight Placement Appraiser determines that Ram procedures were not followed by the team, the 50 pound Bonus for the impact will not be granted, and the Team will have to perform another RAM impact immediately before additional weight may be placed. The decision of the Weight Placement Appraiser is final. Possible procedural issues include:

39. Questions for Appraiser Training Challenge E: Twist-O-Rama 12. After a successful Ram Impact, the Weight Placement Appraiser hands a team member a Bonus Card, which the team member dutifully places on top of the weight stack. A different team member begins to place a new weight. The Weight Placement Appraiser notices that the Ram has not been moved back into the Ram Box. What should the Weight Placement Appraiser do?

40. Questions for Appraiser Training Challenge E: Twist-O-Rama 12.The Weight Placement Appraiser should stop weight placement until the Ram has been fully moved back into the Ram Box. This is considered a safety issue, not a procedural issue. The Weight Placement Appraiser should always stop the action when he/she sees a potential safety issue.

41. A. Central Challenge – Section 5 i.Ram not aligned squarely against the Pressure Board corner. ii.Ram was not pulled all of the way back to the Ram stop. iii.Ram did not impact the same corner as a previous impact. iv.Ram is touched by anything or anybody after released before it stops moving. j. After each successfully completed Ram Impact, the Ram will be removed by a team member to the Ram Box until the next increment of 45 pounds or more is successfully placed on the Structure Tester.

42. A. Central Challenge – Section 6 6. Structure Scoring: It is the intent of the Challenge that the team will create a Structure according to the specifications in A.2 and A.3, and will test the Structure at the tournament. a.If the Structure does not meet the specifications in A.2 and A.3, and if the team is unable to bring the Structure into compliance with the specifications, the Official Weight Held will be zero. However, the team may still present its solution and earn points for other Challenge requirements. b.Any team that does not make a “good faith” attempt to present a Structure for testing may earn points for other Challenge requirements, but they may not advance to the next level of tournament competition. The Appraisers will make this determination. Their decision is final. c.The team will earn points for the Structure based on: i.The Weight Held Ratio (See A.4.j). ii. Creative use of the Structural Materials: The team will be asked to describe their Structure and explain why they chose the various materials. The team’s design will be appraised on how creatively the multiple materials were included and used. iii. The production of a Bill of Materials (BOM) containing a list of all the materials used in building the Structure. Examples, and/or packaging of each material used must be presented with the BOM at Check-In. This BOM will receive points if present, no points if absent.

43. A. Central Challenge – Section 7 g.Story with Twist or Surprise, and Prop or Costume: a.The team will create and present a Story that has an unexpected twist or surprising change. This twist should contain an element of surprise for the Appraisers. i.The team will receive points for the creativity and surprise of the Story twist. ii.The team will receive points for how well the Story is integrated with Weight Placement and Ram Impact delivery. b.The team will build a prop or costume made from only the same material types used in their Structure. i.They must include only all of the same material types used in their Structure. ii.ii. They may only use the material types used in their Structure. No other materials may be used. iii.iii. Only one prop or costume must be built of the same material types as the Structure. All the other props and costumes used in the team’s Presentation may be built of any materials desired. iv.The team will receive points if the material types used to build the one prop or costume are the same material types used to build the Structure, and for the creativity and workmanship of the one prop or costume.

44. A. Central Challenge – Section 7

45. B. Team Choice Elements B.In addition to the above requirements, the team must present TWO creations called “Team Choice Elements” that show off their interests, skills, areas of strength, and talents. The team may create anything they wish for Team Choice Elements including props, music, technical gadgets, costumes, physical actions etc. 1. The team must present both Team Choice Elements as part of the eight-minute Presentation and each Team Choice Element should have a meaningful connection to the team’s Central Challenge solution. Each Team Choice Element must be described briefly on the Tournament Data Form found at the end of this Challenge.

46. B. Team Choice Elements 2. A Team Choice Element may not be a specific item that is required in the Central Challenge that is already being evaluated. A Team Choice Element MAY be a single unique PART of a required item, as long as it can be evaluated as a stand-alone item. Both Team Choice Elements may be presented at the same time ONLY IF both can be easily identified and scored separately. Examples of these can be found in Rules of the Road. 3. Each Team Choice Element will be evaluated in three ways : for the Creativity and Originality of the Team Choice Element, and for the Quality, Workmanship, or Effort that is evident and Integration into the Presentation. Evaluation of Team Choice Elements is subjective.

47. C. Reward Points – Scoring Category 1 The Structure’s Weight Held Ratio Up to 140 points In each competition Level, the Structure with the highest Weight Held Ratio (including the Bonus Weight) will receive 140 points. The score for all other teams in that Level will be based on the percentage of their structure’s Weight Held Ratio compared to the highest Weight Held Ratio in that level. Team’s score = (WHR ÷ highest WHR in Level) X 140 This score added to the scores the team earns for the items listed below will equal the total Raw Score

48. E. Reward Points – Scoring Category 2, 3, and 4 2.How creatively the multiple materials were included and used in the Structure Up to 20 points from A.6.c.ii 3.Structure Bill of Materials and Material Samples 0 or 10 from A.6.c.iii 4.Story with Twist and Prop/Costume Up to 70 points a.Creativity and surprise of Story twist Up to 20 points from A.7.a.i b.How well the Story is integrated with Weight Placement and Ram Impact Delivery Up to10 points from A.7.a.ii c.Material types used to build the one prop or costume are the same material types used to build the Structure 0 or 10 points from A.7.c.iv d.Creativity of prop or costume Up to 15 points from A.7.b.iv e.Workmanship of prop or costume Up to 15 points from A.7.b.iv

Creativity and Originality up to 10 points from B.3 b. Quality, Workmanship, or Effort that is Evident Up to 10 points from B.3 c. Integration into the Presentation Up to 10 from B.3

50. E. Reward Points – Team Challenge Scoring Central Challenge Scoring at a Glance Instant Challenge = 25% Team Choice Elements 60 points = 15% Central Challenge 240 points = 60% –Story w/Twist & Prop/Costume = 30% of the 240 Central Challenge points –Structure Bill of Materials = 4% of the 240 Central Challenge points –Creativity/Workmanship of Structure = 8% of the 240 Central Challenge points –Structure Weight Held Ratio = 58% of the 240 Central Challenge

51. D. Special Procedures for the Structural Challenge 1 & 2 1.1. The Presentation Site a.The minimum dimensions of the Presentation Site will be 16ft x 16ft (4.88m x 4.88m). In most cases, this area will not be marked on the floor. When possible, the tournament may provide a larger Presentation Site. The team may use all of the Presentation space available at their site, but they must be prepared to present in the minimum area specified. The team should keep in mind that the weights, Structure Tester, and Ram will occupy a portion of the Presentation Site. b.The team must not move the Structure Tester from its location. c.A single 3-prong AC electrical outlet will be provided at least to the edge of the Presentation Site. 2. The Structure Check-In Procedure: Prior to the team’s Presentation time, at a time designated by the Tournament Director of each tournament, the team will bring their Structure, a completed copy of Page 2 of the Tournament Data Form, and their Bill of Materials (BOM) to the Structure Check-In Area. The purpose of Structure Check-In is to determine whether the Structure meets the Challenge specifications. The Structure Check-In Area may be at a separate location from the Presentation Site. a.The Structure Check-In Appraisers will always avoid touching the Structure. b. Structure Check-In Appraisers will instruct the team to place their Structure on the scale. Once the scale reading stabilizes, the Structure Check-In Appraisers will verify that the Structure does not exceed 175 grams, and record the official Structure weight to the nearest tenth of a gram on the Structure Check-In Form.

52. D. Special Procedures for the Structural Challenge - 2 c.Next, the Structure Check-In Appraisers will make sure that the team can legitimately test the Structure using a representation of the Tester Base. A team member must place the Structure on the representation of the Tester Base so that a 2in (5.1cm) outside diameter cylinder easily passes through the Structure. The Structure must be able to stand on the representation of the Tester Base without team members holding it. The Appraisers will validate that the Structure does not touch the Safety Supports or Safety Shields. d.While the Structure rests on the representation of the Tester Base, the Appraisers will measure it. They will verify that the Structure is at least 7.5in (19.1cm), and not more than 9in (22.9cm) in height. e.The Check-In Appraisers will make sure that Elementary Level teams constructed the Structure using at least three of the approved Structure Materials. They will make sure that Middle Level Teams constructed the Structure using at least four of the approved Structure Materials. They will make sure that Secondary/University Level Teams constructed the Structure using at least five of the approved Structure Materials. The Check-In Appraisers will reserve the right to recall the Structure to the Check-In Area after the team’s Presentation to verify the team used only materials from the list in A.3.a. If the Check-In Appraisers want the Structure returned following the Presentation, they will note it on the Structure Check-in Form

53. D. Special Procedures for the Structural Challenge - 2 f.The Structure Check-In Appraisers will make every effort, within reasonable scheduling constraints, to allow the team the time to bring their Structure into compliance with the above specifications. Any team whose Structure does not meet the above specifications will receive an Official Weight Held of zero. However, the team may still present their solution and earn points for other Challenge requirements. g.The Check-In Appraisers will also ask the team for their “Bill of Materials” detailing which materials were used in the Structure. They will ask to see samples of each Material used. They will then compare the “Bill of Materials” to the Structure, and determine whether the two agree. If so, the team will receive 10 points. If there is no “Bill of Materials” or the contents of the “Bill of “Materials” deviate from the materials used in the Structure, or there are no Material samples, the team will receive zero points for C.3. h.When Structure Check-In is complete, the team will place their Structure into a team-supplied storage container and the Structure Check-In Appraisers will seal the container. The Structure and the Structure Check-In Form must remain in a designated place in the Structure Check-In Area until approximately 20 minutes before the team’s scheduled Presentation time.

54. D. Special Procedures for the Structural Challenge i.Approximately 20 minutes before the team's scheduled Presentation time, one or more team members must return to the Structure Check-In Area to collect the Structure and carry it to the Prep Area at the Presentation Site. They must bring their Bill of Materials and Material Samples to the Prep Area as well. Team members must not break the seal on the storage container until the Prep Area Appraiser directs the team to do so. j.If a team arrives in the Prep Area with a Structure storage container with a broken seal, the team will be required to return to Check-in to have the Structure re-checked.

55. D. Special Procedures for the Structural Challenge - 3 c. Placement of the Structure on the Structure Tester: During the Presentation, the team will demonstrate the Structure’s ability to support weight using the Structure Tester, weights and Ram that the Tournament Director provides. a.After the Presentation time begins, the team will place the Structure around the Safety Pole and on the Tester Base. The team may adjust their Structure on the Tester Base as needed to place the Structure to their satisfaction before beginning Weight Placement.

56. D. Special Procedures for the Structural Challenge - 3 b.The team may remove the Safety Shields as they place their Structure on the Structure Tester. They must put them back into place before they begin Weight Placement. c.The Structure Tester will sit within the Presentation Area. The team must not move the Structure Tester from its location. The team must not use the weights, or the Structure Tester, or the Ram for any purpose other than testing the Structure during the Presentation.

57. D. Special Procedures for the Structural Challenge - 4 4.Weight Placement Specifics: a.Structure Tester, Ram and Weights: The tournament will provide a Structure Tester shown below and with the dimensions listed in Table 1. The tournament will provide a Ram shown below. The weight preference will be Olympic style metal plates with a 2in (5.1cm) hole in the center. The range of weights and weight style available may vary from tournament to tournament. The team may check with their Tournament Director for specific weights available. The Pressure Board counts as the first weight.

58. D. Special Procedures for the Structural Challenge - 4

60. b.A Safety Line will be marked on the floor at the Presentation Site indicating a distance of 10in (25 cm) from the edge of the Structure Tester on all sides. During Ram impacts, Weight Placement stops, and all team members not operating the Ram must remain behind (not touching) the 10in (25 cm) Safety Line. The Safety Line around the Structure Tester is viewed as an imaginary plane that extends vertically from the floor to the ceiling. c.During the Weight Placement, team members must: i. Use the Structure Tester, Ram, and weights the Tournament Director provides ii. Determine the order in which they will place weights on the Structure Tester iii. Select the weights they will place on the Structure Tester iv. Place weights over the Safety Pole one at a time onto the Structure Tester d.The Pressure Board must be the first weight the team places upon the Structure. The Pressure Board will be clearly marked with its official weight, rounded to the nearest pound. One or more team members may touch the Structure while they place the Pressure Board upon the Structure. Note: If the team wishes to know the specifics of the Structure Tester for their tournament (i.e., the height of the Tester Base, the thickness of the Pressure Board, and/or the actual weight of the Pressure Board), they may check with their Tournament Director.

61. D. Special Procedures for the Structural Challenge - 4 e. Team members must not touch or adjust the Structure or the Structure Tester after placing the Pressure Board unless they first remove the Pressure Board. The Pressure Board may not be removed once a Ram impact has been performed and a bonus given. i.Presentation time will not stop during the removal, adjustment or replacement of weights. ii.Only the weights actually on the Structure at the end of Weight Placement are counted towards the Official Weight Held. (See Section D.7 for a description of when Weight Placement ends). iii.After the Pressure Board is placed, the first Ram impact must be delivered before any weights are placed. See Section A.5. Safety Notes: When a team member’s head is below the level of the Pressure Board AND the Safety Shield in front of the team member’s face is not in place, that team member must wear protective eyewear for safety. When the team member’s head is no longer below the level of the Pressure Board, or when the Safety Shield is in place, the team member may remove the eyewear. The team must provide their own protective eyewear. Because they are used only for safety, protective eyewear are exempt from cost on the Expense Report form. Ordinary glasses are not considered protective eyewear. Protective eyewear is designed with both frontal and side protection for the eyes.

62. D. Special Procedures for the Structural Challenge - 4 Under no circumstances may a team member touch or come into contact with a weight stack that is rotating or moving. Team members and any Adult Assistants who are placing weights must wear closed-toed shoes. Only those shoes that accommodate all five toes in one compartment will be considered closed-toes shoes. When placing a weight, team members should keep their fingers on the sides of the weight so that they do not pinch their fingers. When moving weights, teams should check that there is a clear path to the Structure Tester. f.The Structure must support a weight for a minimum of four seconds, as counted by a Weight Placement Appraiser, for that weight to be included in the Structure’s Official Weight Held. The four-second count for a weight that has been placed begins when no hands are touching any weight on the weight stack. The team does not need to wait four seconds before adding additional weights. The Appraiser’s count is final. g.The Structure must successfully support whatever weights are on the weight stack for four seconds after each completed Ram impact for a Bonus to be awarded. If the Structure continues to support the weight stack after the four seconds, Weight Placement may continue. As soon as 45 pounds or more of weight have been added to the weight stack following the previous Ram Impact, the next Ram Impact must be attempted.

63. D. Special Procedures for the Structural Challenge - 5 6. Adult Assistant: Elementary Level teams may elect to use an Adult Assistant to help place or remove weights of 25lbs (11.34kg) or more. Team members must direct the placement or removal and support the weight to the best of their ability if they use an Adult Assistant. The Adult Assistant: a.May assist in the placement or removal of weights weighing 25lbs (11.34kg) or more. For the purpose of this Challenge, assist means that an adult may help a child lift, move, and set a weight that he/she might not otherwise be able to handle alone. b. Must wait in an area the Appraisers designate until a team member directs them to move towards the weights. The team member will direct the Adult Assistant to the specific weight for which they want assistance. c.Must return to the designated waiting area at any time that a team member is not actively directing him or her to assist with placement or removal of a weight. This means that the Adult Assistant must return to the designated waiting area during the team’s application of Ram Impacts. d.Must only respond to directions from team members or Appraisers.

64. D. Special Procedures for the Structural Challenge - 6 e. Must not direct Weight Placement and/or removal or Ram placement and/or removal in any way. If, in the opinion of the Appraisers, the Adult Assistant is directing ANY aspect of weight selection, placement, or removal, the Appraisers will halt Weight Placement or removal, warn the Adult Assistant of the inappropriate action and remind him/her of the team’s responsibility. The Appraiser will instruct the team to remove any weight(s) that they placed with excess adult assistance or direction. Weight Placement or removal will then resume. Presentation time will not stop. f.If the Adult Assistant engages in any further inappropriate activity, the Appraisers will direct him/her to withdraw from the Presentation Site. Team members must then place or remove any additional weights without the aid of an Adult Assistant and will be limited to weights of less than 25lbs (11.34kg). g.Weights placed, or Ram impacts performed, with inappropriate adult assistance or direction will not count towards the calculation of the Official Weight Held.

65. D. Special Procedures for the Structural Challenge - 7 7.The Weight Placement portion for the testing of the Structure will end when any of the following occur: a. The team elects to stop Weight Placement. The team may do this at any time during the eight-minute Presentation. If the team indicates that testing is completed before the end of the eight-minute time limit, the weights must remain on the Structure Tester until counted by an Appraiser. b. The team declines to do a required Ram impact after the Pressure Board is placed, or after a 45lb increment has been placed on the tester weight stack. Weight Placement Appraisers will inform team members when a Ram Impact is required. c. The Pressure Board or the Structure touches any of the four Safety Supports or any of the Safety Shields of the Structure Tester. A weight or Ram impact that causes the Pressure Board or the Structure to touch the Safety Supports prior to the completion of the 4-second count will not count towards the Official Weight Held total. If the Weight Placement Appraiser cannot slide a single sheet of paper between the Pressure Board and the Safety Support, this means that the Pressure Board is touching the Safety Supports.

66. D. Special Procedures for the Structural Challenge - 7 d. The placed weights reach the mark that is 1in (2.5cm) below the top of the Safety Pole or the extension pipes, when used. The team must not place any further weights on the stack once the weights reach the 1in (2.54cm) mark below the top of the original Safety Pole or the topmost extension pipe, when used. The mark does not have to be visible at that point, but the team must not add any more weights once the weight stack is at or above the mark. e. The eight-minute time limit ends. f.Teams may use the entire eight-minute Presentation time for Weight Placement, regardless of whether or not they have ended the performance of their Story..
