The body consists of two slender uniform rods which have a mass per unit length. The rods are welded together and pivot about a horizontal axis through O against the action of a torsional spring of stiffness k_T. By the method of this article, determine the natural circular frequency w_n for small oscillations about the equilibrium position. The spring is undeformed when θ = 0, and friction in the pivot at O is negligible.
