A heavy disk of mass moment of inertia (J) is attached at the middle of a circular
Question:
A heavy disk of mass moment of inertia \(J\) is attached at the middle of a circular shaft of length \(l\) and diameter \(d\) as shown in Fig. 2.113. By modeling the system as a single-degreeof-freedom torsional system, determine the natural frequency of torsional vibration.
