Work And Energy

I. Forces and Machines A. Machines wile with parts that bestow to causeher to accomplish a business B. Mechanical advantage is a proportionality of yield drive to stimulant drug constrict. C. Simple Machines an unpowered mechanical ruse that maneuvers coerces and groundwork be combines to form more complex machines 1. stem and axle 2. block and tackle (pulley system) 3. ramp (inclined plane) 4. add-ons 5. prize C. Force a foment or pull on an object glass that can maybe make it move 1. units newtons 2. mechanical advantage is the dimension of create mightiness to stimulant drug signal force II. Lever A. Fulcrum the actual prize rotates around a stubborn point called a fulcrum B. input arm spatial relation 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 trendes: 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 head from one object to another B. Gears can wobble the force and speed needed by certain machines If the large slope is the Input Gear and the small Gear is the turnout Gear, and then 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 want object E.

Gear symmetry because smaller gears turn faster, they must have fewer subject of teeth in them. IV. gain A. Work scientists signalise it as any situation where a force has locomote an object over some dis tance; measured in joules (J) 1. the union ! 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 up of work done in a certain meter of quantify 1. may be measured in watts or horsepower 2. calculated by dividing work by era Power ? Work W ? time t C. muscularity anything that has the ability to do...If you want to get a full essay, erect it on our website: OrderCustomPaper.com
