Problem 10.58 The uniform sphere of mass $m$ and radius $R$ can spin freely relative to the shaft AB, whose mass is negligible. The shaft AB precesses about the vertical axis with constant angular speed $\omega_0$. Assuming that the friction between the sphere and the horizontal sur- face above is sufficient to prevent slipping and neglecting friction in the pin at A, deter- mine an expression for the minimum value of $\omega_0$ for which this motion is possible.
