A spur gearset has a pinion speed is 1120 rev/min. There are 17 teeth on the pinion and 51 teeth on the gear. The pressure angle is 20° and the overload factor Ko = 1. The diametral pitch is 6 teeth/in and the face width is 2 in. The pinion cycle life is to be 10^8 revolutions at a reliability R = 0.99. The quality number is 5. The material is a through-hardened steel, grade 1, with Brinell hardnesses of 232 core and case of both gears. For a design factor of 3, what is the capacity in HP of the pinion considering only bending. Use Ks=1.
