Summary

An illustration showing how pulleys are used to obtain a mechanical advantage. Using additional pulleys decreases the force required but increases the distance required to raise a load the same amount. In each instance here the mechanical work done is the same, work being the product of force and distance.

  • FZ × s = FL × h
    • 10 cm × 100 N = 10 J
    • 20 cm × 50 N = 10 J
    • 30 cm × 33 1/3 N = 10 J
    • 40 cm × 25 N = 10 J
