일반물리학 1 — Oscillations: Problem 43

43 In Fig. 15-35, a physical pendulum consists of a uniform solid disk (of radius \(R = 2.35 \text{ cm}\)) supported in a vertical plane by a pivot located a distance \(d = 1.50 \text{ cm}\) from the center of the disk. The disk is displaced by a small angle and released. What is the period of the resulting simple harmonic motion?
