Key Concepts in Pulley Calculations

Mechanical Advantage (MA) is the ratio of load to effort. For an ideal pulley system, MA equals the number of supporting ropes. Our mechanical advantage calculator accounts for real-world factors like friction.

Tension calculation determines the force exerted on the rope. In a perfectly efficient system, tension equals load divided by the number of supporting ropes.

System efficiency measures how much input energy is converted to useful work. Friction, rope material, and pulley condition all affect efficiency.
