The rotation rates ω1 of the bracket supporting the spinning disk are constant. The spin rate of the disk is increasing linearly with elapsed time, so that ω2 = ξt. (a) Describe the angular velocity of the disk in terms of a superposition of simple rotations. (b) Solely from an examination of the description in Part (a), predict the direction(s) in which the angular acceleration of the disk will be situated relative to the xyz axes defined in the sketch, which rotates in unison with the support bracket. Briefly explain your answer. (c) Describe the angular velocity and angular acceleration of the disk in terms of components relative to xyz coordinate system.
