Solving a problem in physics section 47 point 90 mechan

90. Speed n0 flywheel moment of inertia J is equal to 120 kg • m2 is 240 rev / min. Upon termination of a torque on the flywheel under the influence of frictional forces in the bearings I stopped in time t = π min. Assuming constant friction in bearings, determine the moment M friction forces.
