Question

A block and tackle is a rope and pulley system that uses multiple pulleys. It multiples a small force into a large one. If a motor has a weight of about 2500 N and people pull 4 m of rope to raise the motor 1 m, how efficient is the block and tackle?

As you have already learned, work, in the scientific sense, is done only when a force is applied over some distance. Mechanical efficiency also has a very precise, mathematical meaning. Mechanical efficiency is a comparison of the useful work or energy that a mechanical system produces to the work or energy that was put into the system
