Question: An engineer has an odd-shaped 10 kg object and needs to find its rotational inertia about an axis through its center of mass. The object

An engineer has an odd-shaped 10 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 k = 0.50 N ∙ m. If this torsion pendulum oscillates through 20 cycles in 50 s, what is the rotational inertia of the object?
