SUMMARY
To calculate the force required to turn a handle in a pulley system, perform a moment balance calculation about the center of the handle. The force needed to keep the handle stationary (F_0) must be determined first, as the force applied to lift the mass must exceed F_0. The relationship between force (in Newtons) and torque (in Newton-meters) is crucial; while tension in the pulley provides the necessary force, torque is required to rotate the handle effectively.
