On drum 2, the moment of inertia of which with respect to the axis of rotation I = 0.05 kg • m2, the threads are wound, to which are attached weights 1 and 3 with a mass m1 = 2m3 = 2 kg. Determine the kinetic moment of a system of bodies relative to the axis of rotation, if the angular velocity? = 8 rad / s, radii R = 2r = 20 cm. (Response 1.12)
