			=====Description=====

	[https://en.wikipedia.org/wiki/Lever '''Levers'''] are the simplest form of mechanism and may date back to the time of the earliest civilisations. By using a stiff branch resting on a log for example, early man would have been able to move heavy loads such as rocks. This is similar to the way we might use pliers to grip, scissors to cut, or pincers to take out a nail.

			=====Features and Applications=====

	A lever is a rigid beam that can rotate about a fixed point called the '''fulcrum'''. An effort applied to one end of the beam will cause a load to be moved at the other.
