EXERCISE 5.39 The disk is mounted obliquely on its hub, which spins at angular speed about the horizontal arm AB of the T-bar. Consequently, the disk's center line forms a constant angle relative to arm AB. This ro- tation rate is , with = 0 corresponding to the instant depicted in the sketch, where the disk's axis is situated in the vertical plane. Both this rotation rate and the precession rate are constant. The disk's mass is m, whereas the hub and both shafts have negligible mass. De- rive an expression for the force-couple system exerted on the disk by hub B when p = 0. 3R- Ω Exercise 5.39 EXERCISE 5.39 The disk is mounted obliquely on its hub, which spins at angular speed about the horizontal arm AB of the T-bar.
