The six simple machines are wedges, screws, levers, pulleys, wheels and inclined planes. Simple machines make work easier by transferring force from one place to another, changing the direction of a force, increasing a f... More »

A simple machine is a manual device that reduces the effort needed to perform a certain amount of work. These mechanisms alter the direction or magnitude of a force to help increase the ability to lift, push and pull obj... More »

There are six simple machines, including the lever, the wheel and axle, the inclined plane, the wedge, the screw and the pulley. Together, these six form the basis of all mechanized systems that have ever been built. More »

A bulldozer is a compound machine that is made up of several individual simple machines, including levers, wheels and axles, pulleys, gears, wedges and screws. A simple machine is any component that is used to multiply a... More »
