All the levers in the world can be grouped in 3 classes, depending on
how the effort point, the load point, and the fulcrum are lined up.
Class I . . . fulcrum (pivot) is in the middle.
Class II . . . load is in the middle.
Class III . . . effort is in the middle.
Each individual lever can only belong to one class.

What are the description of lever?
A lever is a simple machine that makes work easier for use; it involves moving a load around a pivot using a force. Many of our basic tools use levers, including scissors (2 class 1 levers), pliers (2 class 1 levers), hammer claws (a single class 2 lever), nut crackers (2 class 2 levers), and tongs (2 class 3 levers).
