TM 122 Equilibrium of moments on a differential pulley block

FEATURES:
- Equilibrium of forces and moment1
- Demonstration of the force reduction on a differential pulley block

DESCRIPTION

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 loose pulley 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.


Learning Objectives / Experiments
- Equilibrium of forces
- Equilibrium of moments
- Relationship between force reduction and cord travel
