SCHOOL PROJECT SET PULLEY SYSTEM

A “School Project Set: Pulley System” is a model designed to demonstrate how pulleys work to lift or move objects more efficiently by reducing the effort required. Pulleys are simple machines used in various real-life applications, such as cranes, elevators, and wells, and this project is an excellent way to explore mechanical advantage and force distribution.

Concept

A pulley system uses wheels and ropes (or strings) to lift loads. Depending on the arrangement (fixed, movable, or compound), the pulley system reduces the effort required to lift an object by distributing the weight across multiple points.

Types of Pulley Systems

1. Fixed Pulley: The wheel is fixed in place, and the pulley changes the direction of the force.
2. Movable Pulley: The wheel moves along with the load, reducing the effort needed.
3. Compound Pulley: A combination of fixed and movable pulleys, providing maximum mechanical advantage.

   How It Works

   1. Fixed Pulley: Changes the direction of the force, but the effort is the same as the weight of the load.
   2. Movable Pulley: Reduces the effort needed by distributing the weight, usually halving the force required.
   3. Compound Pulley: Combines the benefits of fixed and movable pulleys, significantly reducing the effort required.
