D2-11 Dievskiy

A constant torque of the frictional forces in the bearings M1 = 80 N m and the moment of the resistance forces caused by the electromagnetic clutch M2 = 60 (1 - e -1,2t) act on the braking shaft. The initial angular velocity of the shaft is ω0 = 15 rad / s. The moment of inertia of the body relative to the axis of rotation is J = 50 kg m2. Determine the angular velocity of the shaft at time t = 3 s.
