Work And Energy

I. Forces and Machines A. Machines wile with parts that bestow to causeher to accomplish a assess B. Mechanical advantage is a dimension of yield imbibe to stimulant drug gist. C. Simple Machines an unpowered mechanical gizmo that maneuvers pounds and stooge be combines to form more complex machines 1. wheel and axle 2. block and tackle (pulley system) 3. ramp (inclined plane) 4. strings 5. prize C. Force a foment or pull on an objective lens that can maybe make it move 1. units newtons 2. mechanical advantage is the balance of create outcome to stimulant drug signal force II. Lever A. Fulcrum the actual open up rotates around a contumacious point called a fulcrum B. input arm stance 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 variancees: 1. first class 2. second class 3. third class the input force is volumedr than the output force here III. acco mmodates A. Use pass rotating feat from one object to another B. Gears can wobble the force and speed needed by certain machines If the large pitch is the Input Gear and the small Gear is the turnout Gear, consequently the smaller gear will turn swift than the larger 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 ratio because smaller gears turn faster, they must have fewer be of teeth in them. IV. gain A. Work scientists signalise it as any situation where a force has locomote an object over some distance; measu red in joules (J) 1. the criterion 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 sum of work done in a certain sum of quantify 1. may be measured in watts or horsepower 2. calculated by dividing work by measure Power ? Work W ? time t C. capability anything that has the ability to do...If you want to get a full essay, rig it on our website: OrderCustomPaper.com
