How does a pulley system work and what are its ... - JSS2 Basic technology Forces and Friction Question

A pulley system consists of a wheel with a grooved rim and a rope or cable that runs along the groove. When force is applied to one end of the rope, the wheel turns, lifting the load attached to the other end. Fixed pulleys change the direction of the applied force, making it easier to lift objects. Movable pulleys reduce the amount of force needed by distributing the load across multiple ropes. This system is advantageous in lifting heavy objects in construction and other applications, as it allows for greater mechanical advantage and easier handling of substantial weights.
