➢ A lever is a rigid, straight or bent bar which is capable of turning about a fixed axis.

Principle: A lever works on the principle of moments. For an ideal lever, it is assumed that the lever is weightless and frictionless. In the equilibirium position of the lever, by the principle of moments,

Moment of load about the fulcrum = Moment of the effort about the fulcrum.
