A machine is anything that multiplies or changes the direction of a force, and a pulley is no exception. This simple machine that consists of a wheel with a rope or cable around it gets its name because we use it to pull things. A fixed pulley changes only the direction of the force,...
Fixed Pulleys With fixed pulleys, the drum is secured to a single spot. Because of this, lifting an object this way may not be any different than if you were lifting it by hand; however, the fixed pulley enables you to change the force’s direction as needed, making it a very convenie...

Wheel and axle: A bicycle is a perfect example of this combination, where a wheel rotates around an axle to help us move efficiently. Pulley: Think of curtains being pulled up using a pulley system – that’s a simple machine at work!
a pulley block. When a forceFis applied to the rope wrapped around the large drum, the rope wrapped around the small two-radius drum winds off of d (radiusr1) and onto D (radiusr2). The forceWon the radius of the pulley block P is easily overcome, and the attached weight is lifted...
Advantages of the Block and Tackle PulleyIt helps to lift heavy loads. In addition to this, the more the number of pulleys, the greater will be its mechanical advantage. It can easily be moved if grease or any oil is applied. It also serves as a belt when applied to an engine. In ...
