2 '14 Scrambler 2014DRAFT SCRAMBL ER!

3 '14 Scrambler '14 Bro. Nigel National Event Supervisor Mr. Dennis Papesh National Event Supervisor DRAFT CAUTION: Please remember that these PPT’s are based on DRAFT rules. There may be some changes when the official rules are published in the Rules Manual.

4 '14 Scrambler 2014 This is what you want it to do… The intent is to have a falling mass propel a cart carrying an egg down a track as quickly as possible and end up with the egg as close to the center of the terminal barrier without… as quickly as possible!!! DRAFT

5 '14 Scrambler 2014 DOING THIS!!! Now you know why it is called SCRAMBLER.... DRAFT or in this case SUNNY SIDE UPPER!!

6 '14 Scrambler 2014 You Tube Views Like this or better like this!!! DRAFT Those were from a few years ago, and a number of things have changed, so let’s get cracking!

7 '14 Scrambler 2014 Construction DRAFT

8 '14 Scrambler 2014 Construction Entire device – Maximum: 1.00 m high, 0.75 m wide and 1.00 m long Could be 1 or 2 parts ALL energy from a falling mass – 2.00 kg max (GPE & KE) Must start with a #2 pencil Stopping mechanism built in No electricity/electronics Egg: large, grade A ‡ Provided by event supervisor ‡ Foremost part of vehicle ‡ Taped to the following….. DRAFT

9 '14 Backstop ¼” dowel for Photogate ¼” dowels for egg support Backstop ff Dimensions: 5 cm x 5 cm x 0.5 in Approximately cm long, must break laser beam at 25 cm above floor Distance to bottom of dowel from floor MUST be between 5 and 10 cm.

10 '14 The Track Starting Line 0.2 m Line Center Line Terminal Barrier Distance 8.70 – m 1.0 m inc: Regionals 0.5 m inc: States 0.1 m inc: Nats 8.2 m Line Center Point Caution: This diagram is NOT in proportion. The track width is only 1.5 m wide. Timed Distance Scrambler 2014DRAFT Terminal Barrier

11 '14 Scrambler 2014 Competition 10 min. to do 2 runs Tip of egg even with starting line, anywhere along it All parts behind starting line Start with pencil ONLY 1 egg allowed – if broken on first run, NO second run! Alignment DRAFT

12 '14 Scrambler 2014 Scoring 5 Time Score: 5 x Run Time (Run Time is the time to travel between 0.2 and 8.2 m lines.) Distance Score: Distance from the pointed end of egg to centerline of the terminal barrier (cm) Run Score = Time Score + Distance Score Whatever run gives you the best ranking is the one counted Tiebreakers DRAFT

13 '14 Scrambler 2014 Penalties Run penalties (Tier 2) ‡ Egg broken ‡ ANY part of egg transport contacts wall besides egg ‡ Transport runs outside lane (at ANY time) ‡ Transport doesn’t travel 8.20 m ‡ Transport passes terminal barrier (Tier 2 and score of 5000) Construction penalties (Tier 3) Ranked tiers DRAFT

15 '14 Scrambler 2014 Building suggestions First and foremost, build early, practice, log, and calibrate as many runs as possible. Use a plastic egg filled with any material to around 65 g Always build just under/over the dimensions!!!! Make the transport as light as possible Perhaps try some different floor surfaces Did I say calibrate? Strongly consider using aligning devices since you need the transport to go as straight as possible DRAFT

16 '14 PROPULSION SYSTEMS DRAFT

17 '14 Scrambler 2014 Single (combined units) (Not recommended) DRAFT

18 '14 Scrambler 2014 Separate units: Mass-push DRAFT

19 '14 Scrambler 2014 Pulley Systems DRAFT

20 '14 DRAFTScrambler 2014 Pulley Systems

21 '14 Scrambler 2014 Miscellaneous Systems Pendulum Weight Slide ‡ Version One: spring (not pictured) Weight Slide ‡ Version Two (pictured) DRAFT

22 '14 Scrambler 2014 Braking Systems Prayer Axle and String Axle and Wing Nut ‡ By far the most common ‡ Wheel revolution ‡ Example Example Miscellaneous
