The given Wheel and Differential Axle is a useful mechanics laboratory apparatus designed to demonstrate the principles of simple machines, mechanical advantage, and velocity ratio. It helps students understand how effort can be reduced by using a wheel-and-axle arrangement with different axle diameters.

The apparatus consists of a 300 mm diameter wheel combined with a differential axle assembly having a 150 mm major axle and a 75 mm minor axle, maintaining a diameter ratio of 1:2:4. The wheel and axle are mounted on a precision shaft supported by bearings, ensuring smooth and efficient rotation during experiments.

A sturdy wall-mounting bracket provides stable support for practical demonstrations. Supplied complete with the required cord, pulley block, and load hangers, but without weights, the apparatus is suitable for schools, colleges, universities, and educational physics laboratories.
