Agear drive consists of a 20o spur pinion with 16 teeth driving a 48-tooth gear. the pinion speed is 300 rev/min, the face width 2 in, and the diametral pitch 6 teeth/in. the gears are grade 1 steel, through-hardened at 200 brinell, made to no. 6 quality standards, a reliability of 0.90. determine the agma bending and contact stresses and the corresponding factors of safety if 5 hp is to be transmitted. use equivalent modulus of e=16.6 mpsi and cma=0.093.
