This all-metal, smooth-running device allows students to quickly understand the mechanical advantage of the wheel and axle. The wheel has a 35 cm diameter, and the axle features three stepped diameters of 20, 10, and 5 cm, all supported by ball bearings mounted on iron brackets. The device is secured using holes in the base or wall. It includes a snatch pulley block, cable, and hooks, but weighing is not included.

Experimental Objective

The object of the experiments is to investigate the performance of a Compound Wheel and Axle. The experiments cover effort, friction and machine efficiency at various loads.
