The top has a mass of 1 kg and radius of gyration of k, = 25 mm
about its axis of symmetry. The top spins and precesses about the
ball-and-socket joint at point O. It's transverse radius of gyration
about point O is k = 63 mm. The spin velocity is ws = 150 rad/s.
• Under these conditions. determine the two possible
precession velocities op of the top.
Determine the kinetic energy of the top for each of the two
possible precession velocities.
