At the moment of starting the electric motor, its rotor is informed of the angular acceleration ε = 30 rad / s2. Determine at this moment the angular acceleration of the body, if the moment of inertia of the rotor relative to its axis of rotation I1 = 24 kg · m2, and the moment of inertia of the body relative to the same axis I2 = 20 kg · m2. (Answer 36)
