Question

A horizontal rod of mass m and length L is pivoted at one end. The other end is supported by a spring of constant k (Figure 5.109). The rod is rotated in a vertical plane by a small angle θ and released. The angular frequency of the SHM is:

TestHub · Accepted Answer

Gravity is balanced at equilibrium. Torque = k L 2 θ and I = m L 2 /3 , so ω = 3 k / m ​ .
