pulley systems

Pulley systems are arrangements of wheels and ropes designed to make lifting or moving heavy objects easier by sharing the load. A pulley wheel changes the direction of the force you'd apply, allowing you to lift with less effort. When multiple pulleys are combined into a system, known as a block and tackle, they distribute weight across several ropes, reducing the amount of force needed. This setup enhances mechanical advantage, making lifting heavy loads more manageable and efficient. Pulley systems are commonly used in construction, theaters, and mechanical devices to facilitate lifting and movement tasks.
