Ring and Disk Moment of Inertia Apparatus
Use this item for studying the dependence of the moment of inertia on the distribution of mass. Roll a metal ring and wooden disk of the same mass and diameter on an inclined plane or a level surface. The moment of inertia is displayed! The product is comprised of a metal ring and a wooden disk of diameter 6″ (150 mm), 2″ (50 mm) thick and both the same mass. When these are rolled down on an inclined plane or on a level surface with the same initial impulse, the difference in acceleration can be studied.

Inclined Plane
Use the Inclined Plane to determine the coefficient of kinematic and static friction, mechanical advantage and efficiency of an inclined plane, etc. It is comprised of a hardwood inclined plane, 24″ (600 mm) L x 4″ (100 mm) W, fitted with a pulley, 0.88″ (22 mm) Dia., mounted at the free end. It is hinged to a horizontal polished wooden base, 18″ (450 mm) L x 4″ (100 mm) W, which is fitted with an aluminum arc graduated both vertically and angularly. The inclined plane can be fixed at any angle up to 45° or at a suitable height with a metal clamping wingnut.
Includes:
• 2 wooden blocks with eyelets, 8″ (200 mm) L x 3″ (75 mm) W and 4″ (100 mm) L x 3″ (75mm) W
• Steel block with hook, 4″ (100 mm) L x 3″ (75 mm) W
• Scale pan 4″ (100 mm) Dia. with cord and hook
