Examples of pulleys include: Elevators use multiple pulleys in order to function. A cargo lift system that allows for items to be hoisted to higher floors is a pulley system. Wells use the pulley system to hoist the bucket out of the well.

What is pulley in mechanical engineering?

In engineering, a pulley is a wheel which has a grooved rim for carrying a line. The pulley turns in a frame or block, with the purpose of either changing the direction of force or transmitting force. The simplest use of a pulley is when one end of the line is pulled to raise a weight at the other end.
