Imagine you started a new job as a design engineer and your first job is to regenerate the work of your predecessor who left in a lurch without properly documenting his latest task. This task is about a pair of steel gears with 200 full-depth, involute teeth. The pinion and the gear have 23 and 63 teeth, respectively. Your predecessor found the contact stress number for the pinion to be 980 MPa. He did not docuiment his intermediate computation steps and you have no other information. Assuming your predecessor correctly computed the contact stress number, what would be your best estimate for the correct bending stress number? The answer is expected to be in MPa.
