Q-3 The tooth numbers for the gear train illustrated are N₂ = 20-T, N3 = 16-T, N4 = 30-T, N6 = 36-T, and N7 = 46-T. Gear 7 is fixed. If shaft-a has an angular speed of a = 18 rad/s (c.w.), a) Determine the magnitude and direction of rotational velocities of shaft-b, gear-3 and gear-4 in revolutions per minute [rpm]. [20 pts.] b) If the input power is Hin = 12 kW, determine the torque transmitted by shaft-a (Ta) and shaft-b (Tb) in [N-m].
