A solid disk with a moment of inertia of 3.53 kg m2 is spinning about its axle such that the disk rotates by 2p radians (1 rev) every 0.300 s. The axle is tilted through an angle of p radians (180°) in a time of 0.28 s.
1. What is the magnitude of the angular momentum of the wheel? (in kg m2/s)2. What is the magnitude of the torque that must be applied to the wheel in order to rotate it through an angle of p radians? (in N m)
