Mar 9, 2022 · A lever system consists of four parts – beam, fulcrum, load, and effort. Beam: A plank made out of wood or metal. Fulcrum: The pivot point about which the beam rests and moves freely.
A lever is a rigid body capable of rotating on a point on itself. Based on the locations of fulcrum, load, and effort, the lever is divided into three types. Also, leverage is a mechanical advantage gained in a system. It is perfect for lifting or moving heavy things.
