Equilibrium of moments on pulleys (TM121)

Equilibrium of moments on pulleys (TM121)

memorable demonstration of the equilibrium of moments

CodeTM121

Description:

  • The TM 121experimental unit illustrates the laws for forming the equilibrium of moments in static systems.
  • The relations between wheel diameter, moment and circumferential force are demonstrated.
  • Two pulleys with different diameters are mounted on a steel shaft, which is itself mounted on ball bearings.
  • Weights can be hung on the cables, making it possible to represent different load cases acting on two pulleys with different diameters.
  • The forces can be varied using weights until equilibrium is reached.
  • The experimental unit is designed to be fixed to a wall.
  • The parts of the experiment are clearly laid out and securely housed in a storage system.
