demonstration of power savings on the differential pulley block

Description:

• The TM 122experimental unit illustrates the equilibrium conditions on a differential pulley block.
• The relation between pulley diameter, lifting force and torque is demonstrated.
• Three pulleys with different diameters are mounted on a shaft, which is itself mounted on ball bearings.
• Weights can be hung on the cables.
• The forces act on the one hand directly on the periphery of the pulley with the largest diameter and another force acts on the pulley with the smaller diameter via a loose roller.
• Using weights, it is possible to vary these forces until equilibrium is reached.
• The experimental unit is designed to be fixed to a wall.
