An engineer wants to find the rotational inertia of an odd-shaped object of mass 11.3 kg about an axis through its center of mass. The object is supported with a wire through its center of mass and along the desired axis. The wire has a torsional constant K = 0.513 N∙m. The engineer observes that this torsional pendulum oscillates through 20.0 cycles in 48.7 s.What value of the rotational inertia is calculated?
