14.6.4
Shaft 1, whose moment of inertia relative to the axis of rotation I1 = 1 kg • m2, rotates with
Angular velocity? 1 = 40 rad / s, shaft 2 is at rest. Find the angular velocity of the shafts
After their adhesion, if the moment of inertia of the shaft 2 relative to the axis of rotation is I2 = 4 kg • m2.
