Pulley System
A pulley system consists of wheels and ropes that makes lifting heavy objects easier. When you pull down on one side of the rope, the wheel allows the other side to lift your load upward. This system can be arranged in various ways, such as a single pulley or multiple pulleys working together, which can increase the mechanical advantage, allowing you to lift heavier items with less effort. Pulleys are commonly used in construction, elevators, and sailing, illustrating their importance in everyday tasks and engineering.

A pulley system consists of a wheel on an axle and a rope or cable that runs along the wheel’s edge. It is used to lift or move heavy objects more easily by changing the direction of force. For example, pulling down on one side of the rope can lift an object on the other side. Pulleys can be arranged alone or in combination, allowing for greater mechanical advantage, which reduces the effort needed to lift something. This principle is commonly applied in cranes, elevators, and various machinery to enhance efficiency and safety in lifting tasks.
