APPARATUS FOR DEMONSTRATION AND INVESTIGATION IN THE STUDY OF THE LAW OF THE MOMENT OF INERTIA

摘要

Apparatus for proving, in reality, the Newton law which explains the moment of inertia. The apparatus is comprised of a permanent magnet (1) which is shaped like a disk, and fixed at the bottom of the apparatus. Facing the upper surface of such magnet, there is provided another magnet (2) which is secured in the middle of a ring (3), by means of the wheel (4). Therefore, the circular body which faces the lower permanent magnet represents in fact a single independent wheel. The ring (3) which crowns such wheel (4) is also an independent magnet which faces a fourth permanent magnet (6) configured like a hollow cylinder. A fifth permanent magnet (20) is secured to the middle of the cover (8) and faces a disk (21) fixed to the upper surface of the wheel (4). All the other poles facing each other have a similar polarity. The apparatus is fixed inside a circular casing (7) wherein a vacuum has been applied. A motor is provided to rotate the wheel (5) at a sufficiently high speed.
