In a physics lab experiment for the determination of moment of inertia, a team weighs an object and finds a mass of 4.98 kg. They then hang the object on a pivot located 0.172 m from the object's center of mass and set it swinging at a small amplitude. As two of the team members carefully count 107 cycles of oscillation, the third member measures a duration of 251 s. What is the moment of inertia of the object with respect to its center of mass about an axis parallel to the pivot axis
