A pulley system with two pulleys is used to lift a 240 N load. The effort required to lift the load is 120 N. Calculate the mechanical advantage of the pulley system.

New from March Performance: Their "Sport Track" serpentine pulley system for B/RB engines (not just the 383 and 440, but also the 361, 400, 413 and 426 Wedge) and 426 Hemi engines.

This unique DIY project reveals how a used clutch pad housing can be transformed into a functional manual pulley, and the result is nothing short of impressive. Wondering how an old part can become a ...

Pulley systems ease lifting with ropes over wheels. Single pulleys change force direction; fixed pulleys change direction; movable pulleys reduce effort. Adding pulleys creates mechanical advantage.
