WebApr 1, 2000 · A one-wheel pulley allows you to change the direction of the force you have to apply to lift the load by pulling down to lift a load upwards. Similarly, a two-wheel pulley splits the weight equally so that each holds only half the weight, allowing you to lift the same weight with half of the force. Where are pulleys used? WebAt the end you can reduce the force slightly and the screw will come to rest. The total work done to move the mass up is independent of how much the mass was accelerated as long as it it at rest at the beginning and end of the exercise - and thus the average force will be exactly as calculated.
