Simple Machines
Simple Machines provide a mechanical advantage and help to amplify the force that can be applied on an object without a motor, hydraulics or other powered mechanism.
Simple machines were first developed to assist humans in movement of heavy objects, but are employed in machines in order to maximize the effect of a motor or engine (e.g., the gears in an automatic transmission in a motorcar). 
Simple Machines include:
- Lever
- Wheel and axle
- Pulley
- Inclined plane
- Wedge
- Screw
