Two wheels are free to spin about the same axle. The moment of inertia of wheel 1 is 2.16 kg m2, and the moment of inertia of wheel 2 is 1.02 kg m2. When the axle is in its initial position, wheel 1 spins clockwise with
an angular speed of 35.00 rad/s, and wheel 2 spins counterclockwise with an angular speed of 39.60 rad/s.
(a) What is the magnitude of the angular momentum of the two disk system in this initial position?
(b) The axle is rotated, or tilted, by 180° to its final position. What is the magnitude of the vector quantity ?L?
(c) The wheels are returned to their initial position, and wheel 2 spins clockwise at 39.60 rad/s. What is the magnitude of the angular momentum of the two disk system in this new configuration?
(d) The axle is once again rotated, or tilted, by 180° to its final position. What is the magnitude of the vector quantity ?L?
