The device features a 30 cm diameter wheel with axles measuring 15 cm and 7.5 cm in diameter, creating a 1:2:4 ratio. A steel axle runs through the center of the wheel, supported by ball bearings in iron brackets. The base includes holes for mounting the apparatus to a wall. The unit is supplied with a snatch pulley block, cable, and hooks, but does not include weights.

Experimental Objective

To study the performance of differential axle and wheel and find its velocity ratio, efficiency and law of machine etc.
