This Pulley Demonstration Activity Set is a complete hands-on teaching kit designed to explain the working of simple machines, pulley systems, mechanical advantage, and work done. Its modular arrangement allows students to build different pulley combinations and observe how effort changes with load, distance moved, and the number of pulleys used.

The set is built on a sturdy 81 × 20 cm wooden base fitted with sockets, a capstan, and an eye hook. It includes three 81 cm support rods of 12.5 mm diameter, eight hook collars, single pulley, triple tandem pulley, quadruple pulley, right-angled clamps, cotton cords, wheel and axle, Tommy bar, brass slotted weights, and weight hangers.

Designed for interactive classroom demonstrations and practical learning, this activity set is ideal for schools, colleges, universities, and educational physics laboratories.
