= A simple machine is a device for overcoming resistance at a point by applying force at some other point. There are mostly 6 simple machines which are a screw, a wedge, lever, inclined plane, wheel and axle. A screw is a thing that holds things together, a wedge is an object that cuts thing, a lever is a rigid bar pivoted about a fulcrum, an inclined plane is plane figure, a wheel and axle is a lever that rotates in a circle. Their fulcrum could be on the left, middle, and or at the end. Each simple machine can be combined to make a complex machine and each has a special uses. So you might see a lot of simple machines and complex machine all around you. Below the page you will see some websites that will help you to understand more about simple machines. =
