Inertia In Rotational Motion Apparatus | ProDynami – 1204
The Inertia In Rotational Motion Apparatus ProDynami – 1204 enables experiments on rotational motion using a rotating rod and ball bearing mounted drum. This Inertia In Rotational Motion Apparatus allows weights to be fitted at marked distances to form a dumbbell-shaped arrangement, with recalculable inertia properties. It includes solid and hollow test cylinders for comparing moments of inertia. The system is accelerated by a weight and cord, with fall time measured using a stopwatch.
The Inertia In Rotational Motion Apparatus ProDynami – 1204 enables experiments on rotational motion in general. This Inertia In Rotational Motion Apparatus allows weights to be fitted to a rotating rod at marked distances from the centre, forming a dumbbell-shaped arrangement. Its inertia properties can be changed easily and recalculated.
Product Overview
The Inertia In Rotational Motion Apparatus enables experiments to be performed on rotational motion in general. Weights can be fitted to a rotating rod at marked distances from the centre. A dumbbell-shaped arrangement is thus created. The inertia properties of this arrangement can be changed easily and recalculated.
The arrangement is fitted to a low friction ball bearing mounted rotating drum. The system is accelerated by a metal weight attached to a cord wrapped around the drum. The time taken for the weight to fall is measured using a stopwatch. The moment of inertia of the object can then be determined. The experiment is set up quickly using the wall mounted stands.

Construction and Design
The Inertia In Rotational Motion Apparatus ProDynami – 1204 is built around a metal rotating rod, 550mm long with a diameter of 10mm. Weights are fitted to the rod using knurled bolts for quick fastening. A dumbbell-shaped arrangement is formed once weights are attached at marked distances from the centre. The rod arrangement is fitted to a ball bearing mounted rotating drum made of anodised aluminium. Solid and hollow test cylinders are included for comparison experiments. The system is accelerated by a metal weight attached to a cord wrapped around the drum. The apparatus is set up quickly using wall mounted stands. This Inertia In Rotational Motion Apparatus is designed for low friction, accurate rotational motion measurement.
