Solution of the D2 B12. The shaft is rotated with an angular velocity w0 = 9 rad / s, the resistance forces begins to decelerate, which moments M1 and M2. The braking torque is proportional to the angular velocity of M1 M1 = 15w. Moment M2 from the friction in the bearings is constant and equal M2 = 100 Nm. Val considered uniform cylinder weighing 200 kg and a radius of 60 cm. Determine the angular velocity of the shaft by 1.5 seconds after the start of braking.
