A homogeneous disk of radius 9 in. is welded to a rod AG of length 18 in. and of negligible weight which is supported by a ball and socket at A. The disk is released with a rate of spin ψ0, counterclockwise as seen from A, with zero rates of precession and notation, and with rod AG horizontal (θ0 = 90?). Knowing that the smallest value of θ in the ensuing motion is 30?, determine

(a) The rate of spin ψ0 of the disk in its initial position,

(b) The rates of precession and spin as the disk passes through its lowest position.
