What is Rope pulley?

A rope pulley is a simple machine that uses a wheel with a groove in it, called a sheave, to change the direction of a force. A rope or cable is threaded through the sheave, and when a force is applied to the rope, it is multiplied by the number of times the rope wraps around the sheave. This makes it easier to lift heavy objects.

Rope pulleys are used in a variety of applications, including:

• Construction: Rope pulleys are used to lift heavy objects, such as beams and girders, during construction.
• Manufacturing: Rope pulleys are used to move materials around factories and warehouses.
• Shipping: Rope pulleys are used to load and unload cargo from ships and boats.
• Mining: Rope pulleys are used to raise and lower miners and equipment in mines.
• Agriculture: Rope pulleys are used to lift irrigation pipes and other farm equipment.
