WebA pulley comprises a wheel and a fixed axle, with a groove along the edges to guide a rope or a cable. Pulleys are what we call simple machines. Without using an engine, they can help multiply the amount of force applied to lift an object. When you put two or more wheels together and run a rope around them, you have created a great lifting machine. WebJul 28, 2024 · Figure 11.2.4: The diagram above shows a multi-stage belt driven system connecting pulley A and pulley D. Pulleys A and B are connected via a belt, then B and C are on the same shaft, then C and D are connected via a belt. With pulleys on the same shaft, the angular displacements, the angular velocities, and the angular accelerations will all ...
