Solved: The 0.25 kg football is spinning at vz = 15 rad>s

Chapter 21, Problem 21-72

(choose chapter or problem)

The 0.25 kg football is spinning at \(\omega_{z}=15 \ \mathrm{rad} / \mathrm{s}\) as shown. If \(\theta=40^{\circ}\), determine the precession about the z axis. The radius of gyration about the spin axis is \(k_{z}=0.042 \ \mathrm{m}\), and about a transverse axis is \(k_{y}=0.13 \ \mathrm{m}\).
