TM 121 Equilibrium of moments on pulleys



  • Impressive demonstration of the equilibrium of moments


Technical Description

The model demonstrates in experiments the laws on the formation of an equilibrium of moments in static systems. Two pulleys made of anodised aluminium with different radii are fitted to a steel shaft mounted on ball bearings. Easy to change loads can be hung on cords via hangers. In this way it is possible to quickly make changes to the peripheral force on the pulleys.

The anodised aluminium base plate is intended for wall mounting.
