• Equilibrium of moments.
  • Demonstration and student experiment on the equilibrium of moments.
  • 2 pulleys made of anodised aluminium.
  • 2 sets of weights.
  • Ball bearing mounted steel shaft.
  • Anodised aluminium base plate.

The model demonstrates in experiments the laws on the formation of an equilibrium of moments in static systems. Two pulleys made of anodized aluminium with different radii are fitted to a steel shaft mounted on ball bearings. Easy to change weight discs can be hung on cords placed around the pulleys. In this way it is possible to quickly make changes to the peripheral force on the pulleys. The anodized aluminium base plate is intended for wall mounting.
