What is the function of a pulley?
Apr 22, 2021 The function of a pulley is to lift heavy objects by changing the direction of the force on a flexible cable. Pulley also functions to mainly distribute the weight evenly which sort of makes the elevator lighter. The pulley serves in many different industries for lifting loads, applying forces or transmitting power.More
