Simple machines

This document summarizes and provides examples of 6 simple machines - the inclined plane, wedge, wheel and axle, screw, lever, and pulley. It then discusses two examples of compound machines that are made up of combinations of simple machines: a can opener contains a lever, wedge, gear, and wheel and axle, while a stapler uses a lever and wedge. Each simple or compound machine is accompanied by an example of its common location in a house.

CompoundA can opener is made up of 4 simple machines. The arms of a can opener is a lever. They open and close on one fulcrum to grip and help open a can. The part that slices open a can is a wedge. As the can opener moves around the can, the wedge cuts through the metal top. The part that grips and helps rotate the can around is a gear. The gear uses energy from the turning handle to spin around. The rotating handle on a can opener is a wheel and axle. When you turn the handle, energy transfer to the gear and wedge, which rotate and open a can.LocationCan Opener – Kitchen Drawer
Compound ContinuedA stapler is made up of 2 simple machines. The top arm of the stapler is a lever. When you push down on it, it transfers energy into a staple. A staple as it pierces paper is a wedge. When you push down on the stapler, it sends out a sharp metal staple which pierces through paper. LocationStapler – Kitchen Cabinet
