TM 611 Rolling disk on inclined plane



  • Comparative determination of inertia of rotation by rolling down an inclined plane and by performing pendulum experiments


Technical Description

This benchtop unit enables basic experiments to be performed on dynamics and is ideal for laboratory experiments. A metal carrier with a three point support is used as an inclined plane for the experiment; the different rotating masses are rolled down this plane. The inclined plane can be precisely aligned using two integrated sprit levels and three bolts. The angle of inclination is adjusted using an adjustment bolt and is indicated by the built-in inclinometer. The inclinometer uses the plumb line principle. A 1000mm ruler is integrated directly into the inclined plane for measuring the travel. The steel rotating masses each have self-centering conical pins. Using a separate pendulum block the moment of inertia of the rotating masses can be determined by swinging.
