Determine an appropriate combination of materials, hardnesses, and manufacturing precision for the gears in Problem 16.21. (State any necessary decisions and assumptions.)

Problem 16.21

A pair of straight-tooth bevel gears mounted on perpendicular shafts transmits 35 hp at 1000 rpm of the 36-tooth pinion-see Figure P16.21. The gear turns 400 rpm. Face width is 2 in., P = 6, and f = 20°. Make a sketch of the pinion showing

(a) an assumed direction of rotation,

(b) the direction and magnitude of torque applied to the pinion by its shaft, and

(c) the direction and magnitude of the three components of force applied to a pinion tooth by a gear tooth. Make a corresponding drawing of the gear and the loads applied to it.
