Mechanical Advantage of A Pulley Calculator

Calculate mechanical advantage of pulleys quickly & easily with our free online calculator. Get accurate results in seconds!

When a small input force is applied to a machine, the magnitude of the output force increases, resulting in mechanical advantage. Pulleys are wheels on a shaft used to move a belt in a forward or backward direction, allowing an object to be lifted. This online calculator can be used to calculate the mechanical advantage of pulleys.

    Mechanical Advantage in Single Pulley

    Mechanical Advantage in Multiple Pulley

    Where:

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