Mechanical Advantage of a Lever Formula - Simple Machines

Lever is a simple machine containing a beam pivoted to a fixed end by fulcrum. The amount of force used internally by this simple machine is called as mechanical advantage of lever. There are three classes of levers : first, second and third. The ratio of the effort arm and load arm is the MA of lever.

Lever Mechanical Advantage Formula

Formula:

Mechanical Advantage of First Class Lever

MA = d1 / d2
Mechanical Advantage Lever First Class


Mechanical Advantage of Second Class Lever

MA = d1 / d2
Mechanical Advantage Lever Second Class


Mechanical Advantage of Third Class Lever

MA = d2 / d1

Mechanical Advantage Lever Third Class



Where,

MA = Mechanical Advantage
d1 = Effort Arm
d2 = Load Arm

Even though the position of the fulcrum varies for the three different types of classes, the formula to find the MA for all the three class of levers are same .
