WebbWhat is a pulley simple machine? A pulley is simply a wheel with a groove and a rope in the groove. It is also called a drum or a sheave. The groove is important because it helps to keep the rope in place. It is used to lift or lower heavy objects. With a pulley, the item to be lifted is tied to one end of the rope. Webb16 okt. 2024 · A simple machine is a mechanical device that changes the direction or magnitude of a force. Generally speaking, these use leverage, also known as mechanical advantage, to amplify force. Six simple machines were defined by Renaissance scientists based on reference to ancient Greek documents.
