Two masses m and m/2 are connected at the two ends of a massless rigid rod of length l. The rod is suspended by a thin wire of torsional constant k at the centre of mass of the rod-mass system (see figure). Because of torsional constant k, the restoring torque is = kθ for angular displacement 0. If the rod is rotated by θ0 and released, the tension in it when it passes through its mean position will be:
