Three disks are spinning independently on the same axle without friction. Their respective rotational inertias and angular speeds are I,? (clockwise); 2I,3? (counterclockwise); and 4I,?/2 (clockwise). The disks then slide together and stick together, forming one piece with a single angular velocity. What will be the direction and the rate of rotation ?net of the single piece?

Two disks are mounted (like a merry-go-round) on low-friction bearings on the same axle and can be brought together so that they couple and rotate as one unit. The first disk, with rotational inertia 3.25 kg m2 about its central axis, is set spinning counterclockwise (which may be taken as the positive direction) at 181 rev/min. The second disk, with rotational inertia 7.95 kg.m2 about its central axis, is set spinning counterclockwise at 879 rev/min. They then couple together. (a)...

Two disks are mounted (like a merry-go-round) on low-friction bearings on the same axle and can be brought together so that they couple and rotate as one unit. The first disk, with rotational inertia 3.00 kg m about its central axis, is set spinning counterclockwise at 550 rev/min. The second disk, with rotational inertia 6.40 kg m about its central axis, is set spinning counterclockwise at 800 rev/min. They then couple together.

Problem 10 Two disks are mounted on low-friction bearings on a common shaft. The first disc has rotational inertia I and is spinning with angular velocity w. The second disc has rotational inertia 2I and is spinning in the same direction as the first disc with angular velocity 2 o as shown. The two disks are slowly forced toward each other along the shaft until they couple and have a final common angular velocity of:

6. (9pt) A disk and a ring are mounted on low-friction bearings on the same axle and can be brought together so that they couple and rotate as one unit. The mass is uniformly distributed throughout the objects. The disk and the ring both have a radius of 10cm and a mass of 4kg. The objects are set spinning about their central axis, the disk at 400rev/min in clockwise direction and the ring at 800rev/min in the opposite direction. They...
