A 11-lb wheel is mounted on a 2-lb plate whose center is attached to a 1.6 in diameter, 30 in long (G = 11606.22 kips/in^2) steel bar, which is fixed at its other end_ The centroidal polar moment of inertia of the plate is 220 slugs-in^2. The period of torsional oscillation of this assembly is 0.15 s. What is the polar moment of inertia of the wheel?
