Wheel and Axle Apparatus

Wheel and Axle Apparatus

The model demonstrates the conditions of equilibrium on a differential pulley block.
Easy to interchange weights permit the load to be varied such that equilibrium is obtained.
Three anodized aluminium pulleys of different diameter are fitted to a shaft mounted on ball bearings.
The forces act, on the one hand, directly on the peripheral of the largest pulley, on the other hand, via a loose pulley on two smaller pulleys.
The model is intended for wall mounting.
