*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*

or

*The ratio of the*

**Resistance Force**and the**Effort Force**or
