Explanation:

Lever is a bar that can rotate around a fulcrum. The levers can be divided into three classes: First Class Levers (Interlocking Levers), Second Class Levers (Inter-Resistant Levers) and Third Class Levers (Interpotent Levers). In the first-class levers, the fulcrum is between the point of application of the force of action and that of the resistance force.
