What are the applications of:
Single-fixed pulley system
Single-movable pulley system
Sheaf pulley systemor block and tackle system of pulleys

Dear student,

fixed pulley’s wheel and axle stay in one place. A good example of a fixed pulley is a flag pole: When you pull down on the rope, the direction of force is redirected by the pulley, and you raise the flag.

Examples of movable pulleys include construction cranes, modern elevators, and some types of weight lifting machines at the gym.

Sheath Pulley System or Block and Tackle System It consists of two sets of pulleys. One set ofpulleys is attached to a rigid support at the top and is called block.
A block and tackle system amplifies the tension force in the rope to lift heavy loads. They are common on boats and sailing ships where tasks are often performed manually.
