What is the point at which the lever pivots?

A The fulcrum
Explaination
The fulcrum of a lever is the support point on which the lever pivots, like the center point of a see-saw. A lever is a simple machine, meaning that it amplifies an input force to provide a greater output force. The fulcrum's position affects the type of lever and the mechanical advantage provided by it.
