TM 122

Wheel and Differential Axle Apparatus

Technical Description

The model demonstrates the conditions of equilibrium on a differential pulley block. Three anodised 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 roller on two smaller pulleys. Easy to interchange weights permit the load to be varied such that equilibrium is obtained. The model is intended for wall mounting, however the model can also be attached to the TM 090 Vertical Stand available as an accessory.

Learning Objectives / Experiments

· Equilibrium of forces
· Equilibrium of moments
