The position of the fulcrum, resistance, and effort vary in first-class, second-class, and third-class levers. Introduction: A level is a rigid, elongated object that helps in the movements of the body parts. Muscles and bones together make a lever. The levers are divided into three classes, first, second and third. There is a fixed point around which the levers move. Examples of a lever are a seesaw, scissors, bottle openers, nutcrackers, human arms, legs, etc.
