memorable demonstration of the equilibrium of moments

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.
