The design characteristics of a gear-reduction unit are under review. Gear B is rotating clockwise with a speed of 300 rev/min when a torque is applied to gear A at time t = 2 s to give gear A a counterclockwise angular acceleration α which varies with time for a duration of 4 seconds as shown. Determine the speed N_B of gear B when t = 6 s.
