What are the main parts of a lever?
There are three parts to all levers: • Fulcrum – the point at which the lever rotates. Input force (also called the effort) – the force applied to the lever. Output force (also called the load) – the force applied by the lever to move the load. There are three types of levers: first class, second class and third class.

This always occurs with third-class levers and may occur with first-class levers. When the input and output forces are the same distance from the fulcrum, the output force equals the input force, and the ideal mechanical advantage is 1. This occurs only with first some first-class levers.
