1. The problem statement, all variables and given/known data In the experiment, you will study an oscillator called a "torsion pendulum." In this case, the restoring "force" is the torsion constant of the wire that suspends the weight X and the inertial term is the rotational inertia of the suspended mass. You will compare the periods of a suspended sphere and of a suspended cube. The rotational inertia of a sphere is Is = 1/10M_sD^2 where ms is the mass of the sphere and D is its diameter. The rotational inertia of a cube is Ic = 1/6m_S^2 where mc is the mass of the cube and S is the length of its side. If the cube and the sphere are suspended from the same wire, what is the expected ratio of their periods, Tc/Ts? Assume that D = S ms = 0.20kg and mc = 0.9 kg 2. Relevant equations T=1/f, omega = 2pi*f 3. The attempt at a solution so for this one I know that I can get the moment of inertia and get the angular frequency but I don't know what the restoring force constant k is. is that constant require or would it cancel out later on?
