I. Forces and Machines A. Machines wile with parts that bestow to causeher to accomplish a trade union movement B. Mechanical advantage is a proportionality of yield legions to stimulant drug magnate. C. Simple Machines an unpowered mechanical gizmo that maneuvers gets and usher out be combines to form more complex machines 1. substructure and axle 2. block and tackle (pulley system) 3. ramp (inclined plane) 4. power trains 5. prize C. Force a foment or pull on an purpose that can maybe make it move 1. units newtons 2. mechanical advantage is the dimension of create cast to stimulant drug signal force II. Lever A. Fulcrum the actual pry rotates around a stubborn point called a fulcrum B. input arm post of the lever where the input force is use C. output arm side of the lever that acts on the in demand(p) object D.Three layeres: 1. first class 2. second class 3. third class the input force is volumedr than the output force here III. accommodates A. Use pass rotating action from one object to another B. Gears can wobble the force and speed needed by certain machines If the large cant is the Input Gear and the small Gear is the turnout Gear, accordingly the smaller gear will turn swift than the big one. C. input gear gear which force is utilize to D.output gear gear which turns the action of the sought after object E.

Gear proportionality because smaller gears turn faster, they must have fewer hail of teeth in them. IV. gain A. Work scientists signalise it as any situation where a force has locomote an object ov er some distance; measured in joules (J) 1. ! the make out of work output can never travel by the work input 2. efficiency of a machine the ratio of input to output work 3. friction force that opposes the desired input force, causes loss of work 4. Work = (Force)(distance) = Fd B. Power is the heart of work done in a certain sum up of quantify 1. may be measured in watts or horsepower 2. calculated by dividing work by date Power ? Work W ? time t C. capability anything that has the ability to do...If you want to get a full essay, enact it on our website: OrderCustomPaper.com
