A lever is that mechanical device which is mainly found responsible for amplifying the input force in order to provide a greater output force which is intended to provide leverage. The ratio of the output force to that of the input force is termed as the mechanical advantage of the lever.

Levers are machines used to increase force. We call them “simple machines” because they have only two parts, the handle, and the fulcrum. The handle or bar of the lever is called the “arm”, it’s the part that you push or pull on.
A lever is a mechanism that can be used to exert a large force over a small distance at one end of the lever by exerting a small force over a greater distance at the other end. The moment action on both sides of the lever is equal and can be expressed as. F e d e = F l d l (1) where . F e = effort force (N, lb)
The lever is a movable bar that pivots on a fulcrum attached to a fixed point. The lever operates by applying forces at different distances from the fulcrum, or a pivot. As the lever rotates around the fulcrum, points further from this pivot move faster than points closer to the pivot.
A lever is a rigid beam that pivots around a fulcrum. Levers can exchange the amount of force it takes to move an object with the distance that the actuating force has to move. The relative distances from the fulcrum will affect the amount of this mechanical advantage.
As workholding tools, levers are used for adjusting, aligning, and tightening machine elements. Different machines require specific types of levers to operate. Picking the right one for your assets helps improve overall efficiency, productivity, and safety.
