A 173-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 15.6 kg·m2, and when it is swung at small amplitudes, it is found to oscillate at a frequency of 0.739 Hz. How far is the pivot from the sculpture's center of mass?
A mercury thermometer is free of all markings. The thermometer is placed in an ice bath. When the thermometer is in equilibrium with the ice bath the position of the mercury column is marked on the glass.
