Suppose that the gears in Figure 15.28 (page 669 of textbook) are identical, each having an 8-in diameter, 80 teeth and 20° pressure angle. Assume that their finish and accuracy correspond to about the best that is commercially obtainable with a shaping cutter. (a). Which of the gears is the most vulnerable to tooth-bending fatigue failure? Why? (b). If the motor rotates 1200 rpm, determine the proper values for V, P, p, Kv, and J.
