The 4-oz top with radius of gyration about its spin axis of 0.62 in. is spinning at the rate p = 3600 rev/min in the sense shown, with its spin axis making an angle θ = 20° with the vertical. The distance from its tip O to its mass center G is Determine the precession Ω of the top and explain why θ gradually decreases as long as the spin rate remains large. An enlarged view of the contact of the tip is shown.
