Mechanical advantage Formula – MA formula

Last updated on December 4th, 2022 at 03:09 pm

In this post, we will talk about the Mechanical advantage formula (MA formula) for different simple machines.

Mechanical advantage Formula | MA formula

The Mechanical advantage formula (MA formula) can be written as follows:

(1) Mechanical Advantage MA = output force/input force
(2) Mechanical Advantage MA = resistance force/effort force.
The machine uses this resistance force to lift or pull a load. So resistance force is equal (magnitude-wise) to the load overcome by the machine.
Therefore, we can also write
(3) Mechanical Advantage MA = Load / Effort

Write different forms of Mechanical Advantage Formula

The mechanical advantage, MA, of the machine can be formulated as the
1> The ratio of the output force and the input force
2> The ratio of the Resistance Force and the Effort Force
3> The ratio of the Load overcome and the applied Effort Force.
