Q. Two masses m and
m2 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
τ=kθ for angular displacement
0. If the rod is rota ted by
θ0 and released, the tension in it when it passes through its mean position will be:
