1 Agricultural Engineering Agriscience

2 Careers In Agricultural Engineering Ag. Safety Engineer Tractor Mechanic Machinery Assembler Irrigation Engineer Lawn Tractor Mechanic Ag Equipment Designer

3 Careers In Agricultural Engineering Engineering Careers Designers Four year degrees (B.S) Mechanical Careers Operators Majority are two year degrees Education varies with the type of working conditions

4 Safety Objective Interpret personal safety hazards related to careers and work in the field of agricultural engineering

5 Safety 50% of all farm related accidents involve working with machinery The definition of safety: Developing an environment free from danger, risk, or injury Impossible to accomplish The #1 key to shop safety is the people who use it!

6 Principles of Safety 1. Keep the shop clean 1. Prevents tripping and related injury 2. Remove unnecessary hazards 1. Example- oily rags 3. Make sure all safety shields are in place 4. Do not use broken equipment

7 Principles of Safety 4. Wear appropriate protective clothing and devices 1. Safety glasses and goggles to protect against dust and flying objects 2. Steel toed shoes 3. Ear plugs where noise exceeds 90dB (decibels)

8 Equipment and Tool Safety Hammers Make sure the handle of the hammer fits tightly on the head Do not strike a hard steel surface with a steel hammer (ex hammer vs. hammer) Always wear safety glasses Discard a hammer with a chipped or mushroomed face Replace loose or cracked handles Discard hammers with cracked claws or eye sections

9 Portable Circular Saw Keep the fingers away from the trigger when carrying the saw Do not wedge the guard in the open position The blade rotates at a very high speed never place on a surface before the blade stops Prevent Kickback Do not start the saw with the blade touching the stock (wood)

10 Safety Color Coding Development National organizations worked together American Society of Agricultural Engineers Safety Committee Of the American Vocational Association

11 Safety Color Coding Red Areas of danger Safety switches Fire extinguishers Red = Danger

12 Safety Color Coding Orange Wheels Levers Knobs Orange = Warning

13 Safety Color Coding Yellow Wheels, levers, and knobs that adjust or control machines Yellow = Caution

14 Safety Color Coding Blue Out of Order Broken shop equipment Blue = Information

15 Safety Color Coding Green First Aid Safety Equipment Green = Safety

16 Fire Hazards The Fire Triangle Components necessary for a fire to take place 1. Fuel Any combustible material that will burn 2. Heat Most material will burn if they are made hot 3. Oxygen Gas in the air that is not a fuel but must be present for material to burn

17 Fire Hazards Fire Prevention Take away one of the components of the fuel triangle Fire will stop or will not start Safe storage of fuels Clean shop facilities

18 Fire Extinguishers Know the kind of fire: Class A- Ordinary combustibles paper, wood, cloth Class B- Fuel fires gas, oil Class C- Electrical fires Class D- Combustible metals

19 Fire Extinguishers C A B

20 Smothering a fire Best used of a person whose clothes are on fire Wrap the person in a blanket to cut off the oxygen to the fire

21 Planning An Agricultural Project Blueprints are used to plan projects Simple designs Sharp lead pencil with an eraser Protractor Ruler (12) Compass

22 Planning An Agricultural Project Detailed plans Drawing board to attach paper Masking tape T square for drawing horizontal lines Right triangle for vertical lines Scale Instrument with increments shortened according to proportion 1. Flat scale- looks like a ruler 2. Triangular scale- three sided, but 6 scales

23 Planning An Agricultural Project The basics of drawings Sketch Rough drawing with no demensions Pictorial drawing Shows all three views 1. Top 2. Side or end 3. Front

24 Planning An Agricultural Project

25 The basics of drawings (continued) A scale drawing represents objects in exact proportions If the scale is ¼=1 then ¼ on the drawing would equal 1 foot on the object So…. A 2 line on the drawing would equal what on the object? 8 feet Scale will vary depending on the size of the object

26 Class Assignment: Your group will construct a 6 foot picnic table using the materials provided. Your grade will depend on how well you follow the blueprint and how well you complete the project.

27 Planning An Agricultural Project Determining Materials Bill of material List and description of materials needed to complete a project BF= board foot

28 Board Feet Thickness (inches) X Width (inches) Length (feet) 12 How many board feet are in a board 1 X 12 X 8? 1 X 12 X 8 12 BF = 96 12 = 8 BF

29 Board Feet Assignment: Calculate the board feet required to build our class project (24) 2X6X12 (4) 2X6X10 (8) 2X4X10
