A 185-kg sculpture hangs from a horizontal rod that serves as a pivot about which the sculpture can oscillate. The sculpture\'s moment of inertia with respect to the pivot is 16.7 kg·m2, and when it is swung at small amplitudes, it is found to oscillate at a frequency of 0.734 Hz. How far is the pivot from the sculpture\'s center of mass?
