Question: The two fixed counterrotating pulleys are driven at the same angular speed (omega_{0}). A round bar is placed off center on the pulleys as shown.

The two fixed counterrotating pulleys are driven at the same angular speed $\omega_{0}$. A round bar is placed off center on the pulleys as shown. Determine the natural frequency of the resulting bar motion. The coefficient of kinetic friction between the bar and pulleys is $\mu_{k}$.
