The double-reduction helical gearset shown in the figure is driven through shaft a at a speed of 780 rev/min. Gears 2 and 3 have a normal diametral pitch of 12 teeth/in, a 30° helix angle, and a normal pressure angle of 20°. The second pair of gears in the train, gears 4 and 5, have a normal diametral pitch of 8 teeth/in, a 25° helix angle, and a normal pressure angle of 20°. The tooth numbers are as follows: N2 = 14, N3 = 48, N4 = 16, N5 = 34. If the gear set transmits 17 horsepower, calculate the output torque on gear 5, in inch-lbf. 5 E SIXE F HEN B

Question
![The double-reduction helical gearset shown in the figure is driven through
shaft a at a speed of 780 rev/min. Gears 2 and 3 have a normal diametral pitch of
12 teeth/in, a 30° helix angle, and a normal pressure angle of 20°. The second pair
of gears in the train, gears 4 and 5, have a normal diametral pitch of 8 teeth/in, a
25° helix angle, and a normal pressure angle of 20°. The tooth numbers are as
follows: N2 = 14, N3 = 48, N4 = 16, N5 = 34.
If the gear set transmits 17 horsepower, calculate the output torque on gear 5, in
inch-lbf.
