7Objective 6.02Understand basic agricultural engineering principles and practices.
8Shop Safety Awareness and Principles for Safety Of all farm related accidents, nearly 50% involve working with machinery.SafetyDeveloping an environment free from danger, risk or injury.Keys to shop:Trained in safe and proper tool operationsPass a safety test prior to using the shopKeep the shop cleanRemove unnecessary hazards suchoily ragsMake sure all machines have safety shields in place
9Shop Safety Awareness and Principles for Safety Wear appropriate personal protective clothing and devices. For example:Safety glasses or gogglesLeather steel-toed shoesEar protection (plugs or muffs)hearing loss when the noise level exceeds 90 dB (decibels)Other safety clothing may be required for certain work such as welding
10Safety Color Coding in the Agricultural Mechanics Shop National organizations worked together to develop the systemThe American Society of Agricultural Engineers and the Safety Committee of the American Vocational Associationalerts people to dangers and hazardsprovides information to help on react quickly in an emergencyconveys a special message based on a standard code
11Basic Safety Code Colors REDIdentifies areas of dangerRed is used on safety switches and fire extinguishersRed = Danger
12Basic Safety Code Colors ORANGEDesignates machine hazards, such as edges and openingsIt is also used as background for electrical switches, levers and controlsOrange = Warning.
13Basic Safety Code Colors YELLOWIdentifies wheels, levers, and knobsadjust or control machinesYellow = Caution
14Basic Safety Code Colors BLUEUsed on signs such as “Out of Order”identify broken shop equipment that does not work or does not work properlyBlue = Information
15Basic Safety Code Colors GREENIndicates the presence of first aid and safety equipmentGreen = Safety
16Fire Hazards in the Agricultural Mechanics Shop Fire TriangleComponents necessary for a fireFuel – Any combustible material that will burnExamples: oily rags, sawdust, paper, etc.Heat – Most materials burn if they are made hot enoughOxygen (O) – Not a fuel, but must be present for fuels to burn
17Fire Hazards in the Agricultural Mechanics Shop Fire PreventionTake away one of the components of the fire triangle and fire will not start or will stop if already started.Safe storage of fuels or combustible materialsStore fuels in approved containersClean shop facilities
18Extinguishing Fires Fire Extinguishers Know the kind of fire extinguisherClass A Fire Extinguishers use water to control ordinary combustiblesKnow the placement of fire extinguishers so that time is not taken looking for the extinguisher if a fire occurs.hung on walls within easy reach in areas where fires would most likely occurKnow how to useheld upright, the ring pin is pulled, and a lever is pressednozzle of the extinguisher toward the base of the fire
19Extinguishing Fires Other examples Wrapping a person in a blanket whose clothes are on fireeliminates oxygen from getting to the fireCooling with water from a hose or bucket a burning container of paper
20Planning an Agricultural Engineering Project Simple Project DesignsSharp lead pencilProtractor for drawing and measuring anglesGood eraser for making correctionsA twelve-inch rulerCompass for drawing circles and arches
21Planning an Agricultural Engineering Project More Detailed PlansDrawing boardMaskingThe T squaredrawing horizontal linesThe right triangle (30, 60, 90 degree triangle) in conjunction with the T square, is used to draw vertical lines.The scaleInstrument with all increments shortened according to proportionFlat scale – looks similar to a ruler.Triangular scale – three sided, but six scales
22Planning an Agricultural Engineering Project Large Scale ProjectsCAD (computer- aided design)reduce design time for large scale projects
23Planning an Agricultural Engineering Project Basics of DrawingSketchrough drawing that is not to scaledoes have dimensions includedPictorial drawingshows all three dimensions at onceFrontside (end)top
24Planning an Agricultural Engineering Project Basics of DrawingScale drawingrepresents an object in exact proportion¼” =1’¼” on the drawing would equal 1’2” line on the drawing would equal 8’Scale will vary depending on the size of the object being drawn
25Reading a Tape Rule Display units of measure U.S. customary systemMetric systemMarked to show halves, quarters, eighths, and sixteenths of an inchTypically, vertical lines of different heights represent these various intervals
26Wood Projects Nails Screws Bolts Gluing Fastest way to fasten wood Nail hammer or nail gun are the preferred toolsScrewshold better than nailsflathead screw is the one most used in woodworkingPhillips head is preferredBoltsfastening wood at high stress pointsGluingglued wood joint will be as strong as the wood itselfGluing is often accompanied by nails, screws, etc.Boards are held in place for gluing by clampsBar clamps are one type of clamp used
27Metal ProjectsSteelmost commonly usedat least 4 kinds of steelSoapstonesoft, gray rockshows up well on most metalsThe hand tool most often used for cutting metal is the hacksawHacksaws are especially useful for cutting thin conduitMetal cutting band saws and power hacksawsused for large projects
28Objective 6.03Remember tools and their safety practices related to the agricultural mechanics industry.
29Safety using Hand Tools Use the correct tool for the jobKeep and use tools that are in good working conditionUse tools skillfullyWear appropriate protective clothing and devicessafety glassessteel- toed shoesear protection
30Tools used in Agricultural Mechanics Layout and measuring tools– used to measure or mark materials.Chalk line reelmarking straight linesTape rulestraight or curved measuring, most to the 1/16thCombination squaredetermining 45 and 90 degree anglesTry square90 degree squaringLevelleveling and plumbing
31Tools used in Agricultural Mechanics Saws – used to cut materialsHacksawsawing metalPortable circular sawsawing wood in construction projectsCircular carbide saw bladeblade for use on portable circular sawCoping sawcutting curves and irregular cutsPortable jig sawmaking irregular cuts
32Tools used in Agricultural Mechanics Boring tools – used to make holes or change size or shape of holes.Countersinkflaring top of hole for recessing head for flathead screw or boltMasonry bitBoring in concrete, brick or blockPotable electric drilldrilling holes with an external source of electricityStraight shank drill bitdrilling metalSpeed bore bitwood-boring bit for electric drill
33Tools used in Agricultural Mechanics Hammers and driving toolsBall pein hammer – hammering metalNail hammer – driving nailsNail set – countersinking nail headsPin punch – driving out metal pinsSledgehammer – heavy hammering
34Tools used in Agricultural Mechanics Pliers and holding toolsLong nose pliers – reaching into recessed areasSlip joint pliers – adjust for holding various size materialGroove joint pliers – gripping when greater pressure is neededC clamp – clamping two or more pieces of metal togetherDrill press vise – holding stock while drilling
35Tools used in Agricultural Mechanics Wrenches are used to turn nuts, bolts, or screwsAdjustable wrench – turning various size nuts and boltsCombination wrench – turning hex and square nuts and boltsPipe wrench – turning and holding metal pipeRegular socket – general- purpose socket for turning nuts and boltsOpen end wrench –turning square head nuts and bolts
