A torsion pendulum consists of two small point masses, each of mass m = 0.5 kg mounted on the ends of a uniform rod of length l = 0.75 m and of mass M = 2 kg. The system is suspended from a wire of negligible mass attached to the center of the rod and set into torsional oscillation. The torsion constant of the wire is κ = 1.2 N m/rad. (a) [4 points] Question: Derive a symbolic, simplified expression for the moment of inertia I of the torsion pendulum about an axis along the wire in terms of the masses m and M, and the length l of the rod.
