GPT-4o mini
The simple machine you are referring to is called a **pulley**. A pulley consists of a wheel with a groove around its circumference, and it is used to change the direction of a force or to lift heavy objects more easily by using a rope or cable that runs through the groove. Pulleys can be used individually or in combination (known as a block and tackle) to gain mechanical advantage, making it easier to lift loads.
