Solve Prob. 21–64 when θ = 90°.

Solve Prob. 21–64

The top consists of a thin disk that has a weight of 8 lb and a radius of 0.3 ft. The rod has a negligible mass and a length of 0.5 ft. If the top is spinning with an angular velocity ω_s = 300 rad/s, determine the steady-state precessional angular velocity ω_p of the rod when θ = 40°.
