How Do U Calculate The Mechanical Advantage Of A Pulley

Introduction & Importance

Mechanical advantage of a pulley is crucial in physics and engineering, enabling us to calculate the force required to lift a load using pulleys…

How to Use This Calculator

1. Enter the load (N) you want to lift.
2. Enter the force (N) you’re applying.
3. Select the number of pulleys.
4. Click ‘Calculate’.

Formula & Methodology

The mechanical advantage (MA) of a pulley is calculated as:

MA = Load / Force

For multiple pulleys, MA = 2^(n-1), where n is the number of pulleys.
