Question:

The 3-oz top shown is supported at the fixed point O. The radii of gyration of the top with respect to its axis of symmetry and with respect to a transverse axis through O are 1.05 in. and 2.25 in., respectively. Knowing that c = 1.875 in. and that the rate of spin of the top about its axis of symmetry is 1800 rpm, determine the two possible rates of steady precession corresponding to θ =30?.
