# Mechanical Advantage of a Pulley Calculator

When the small input force applied on a machine increases the magnitude of the output force, it produces mechanical advantage. Pulley is a wheel on a shaft used for the movement of a belt along its circumference. The movement can be forward or backward in order to lift an object. This online calculator is used to find the mechanical advantage of pulleys.

#### Formula:

MA = 2 * n Mechanical Advantage in Single Pulley

Where, MA = Mechanical Advantage of Pulley n = Number of Movable Pulleys Feffort = Force / Effort put for Load Fload = Pulley Load

### Example:

#### Mechanical Advantage of a Pulley

If the number of pulleys is 6, then
MA = 6 *2
MA = 12
