5 teeth/in with an 18-tooth 20° pinion driving a 45-tooth gear. The power input is
32-hp at 1800 rev/min. Find the direction and magnitude of the forces acting on
bearings A, B, C, and D.
13-41 The figure shows the electric-motor frame dimensions for a 30-hp 900 rev/min motor.
The frame is bolted to its support using four -in bolts spaced 11 in apart in the view
shown and 14 in apart when viewed from the end of the motor. A 4 diametral pitch
20° spur pinion having 20 teeth and a face width of 2 in is keved to and fluch with
