2. the gearset for a precision enclosed gear drive mates a 20° normal pressure angle helical 16-tooth pinion and 48-tooth gear set, each with a helix angle of 30° a normal diametral pitch of 6 teeth/inch, and face width is 2 in. for both full thickness (k8 = 1) gears. the geometry factors for bending strength are jp = 0.423 and jg = 0.529. the pinion transmits 5 hp at 300 rpm from a uniform source to a uniform load. the gears are grade 1 steel, through-hardened at 200 brinell, made to no. 6 quality standards. they are uncrowned and to be accurately and rigidly center mounted. assume a pinion life of 108 cycles and a reliability of 0.90. determine the agma bending and contact stresses and the corresponding factors of safety.
