Pulley Mechanical Advantage Formula

Pulleys are one of the simple machines used to apply force on an object, life any load, and transmit power. It is a wheel on a shaft that supports the movement of a belt or cable along at its circumference. The mechanical advantage that is gained with the pulleys is calculated using the formula 2 * number of movable pulleys.

Formula:

MA = 2 * n

Where,

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