Same question is answered on chegg and that answer is wrong..So please don't copy the same answer else I will devote your answer.. Kindly read the question properly and give correct answer explaining all the steps (good handwritten).. I will upvote surely!!!

Extracted text: The steel pinion of Problem 14-4 is to mesh with a steel gear with a gear ratio of 4:1. T he Brinell hardness of the teeth is 200, and the tangential load transmitted by the gear s is 6 KN. If the contact fatigue strength of the steel can be estimated from the AGMA f ormula of S. = 2.22 H3 + 200 MPa, estimate the factor of safety of the drive based on a surface fatigue failure Problem 14-4 A steel spur pinion has 16 teeth cut on the 20° full-depth system with a module of 8 m m and a face width of 90 mm. The pinion rotates at 150 rev/min and transmits 6 kW to the mating steel gear. What is the bending stress?
