The 85-g 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 21 nun and 45 mm. respectively. Knowing that c = 37.5 nun 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 θ= 30°.
