An engineer has an odd-shaped 13.5 kg object and needs to find its rotational inertia about an axis through its center of mass. the object is supported on a wire stretched along the desired axis. the wire has a torsion constant κ = 0.618 n·m. if this torsion pendulum oscillates through 28 cycles in 58.1 s, what is the rotational inertia of the object?
