6) [20 pts) Bending Stress in a Gear A steel spur pinion has a pitch of 6 teeth/in, 22 full-depth teeth with a cut profile, and a 20° pressure angle. The pinion runs at a speed of 1280 rev/min and transmits 15 hp to a 60-tooth gear. If the face width is 2 in., estimate the bending stress. Take the value of Lewis form factor, Y, from the table 14-2. The bending stress is kpsi.
