Q-10 (10 points) A There is a combined object of rod (mass mi-3.5kg and length L=1.6m) and Rod a disk (mass m2-1.8kg and radius r=22cm) which oscillates on xy plane with one end of the rod is fixed. Combined object oscillates in simple harmonic oscillations, SHM) with small angle oscillations. When 8 - 120 , is small, sine ~ 0. DISK a Find the total moment of inertia of the combined object which oscillates at fixed axis on A? (3 points) Find the net torque acts on the object at point A? (4 points) c) Find the period of the oscillation of the combined object? (3 points)
