A disk of mass \(m\) is mounted between two shafts with different properties, as shown in Figure 2.39.

(a) What is the natural frequency of the system?

(b) If the disk is rotated \(\theta\), where \(\theta \ll 1 \mathrm{rad}\), and then released, what will its angular position be at an arbitrary time \(t\) ?
