There are three types of levers — class l, class 2 and class 3.
A lever is a rgid bar that is used with a point of support or a fulcrum. The mechanical force or effort is applied on one end of the lever, F, with the aim of counteracting the resistance or load, R which acts on the other end of the lever
The lever is balanced when the effort F, multiplied by its distance d is equal to the load R multiphed by its distance from the fulcrum r This is called the law of the lever, which is expressed by this equation:
F x d = R x r
