In Figure 13-34 an electric motor transmits 1-hp at 1800 rev/min in the clockwise direction, as viewed from the positive x-axis. Keyed to the motor shaft is an 18-tooth helical pinion having a normal pressure angle of 20°, a helix angle of 30°, and a normal diametral pitch of 12 teeth/in. The hand of the helix is shown in the figure. Calculate the forces acting on the pinion and the bearing reactions at A and B. The thrust should be taken out at A. 10 in- 36T B Fig. 13-34 3 in 18T
