Two Lifting Lifting Pulley's Mechanical Advantage

Mechanics and Machines Calculations Menu

Two pulleys may be configured as shown to reduce the the required force F to lift a weight. The velocity which the
weight W will be raised equals one-half the velocity of the force applied at F.

Mupltiple Pulleys

F = W/2
W = 2F

Where:

W = Unknown weight
F = Applied force
