D2-08 Dievskiy

The platform, which was at rest, is driven into rotation by a constant moment M1 = 1800 N m. In this case, the moment of the resistance forces M2 = 120ω arises. The radius of inertia of the platform relative to the axis of rotation is ρ = 1.5 m, its mass m = 500 kg. Determine the angular velocity of the platform after 5 seconds after the start of the movement.
