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 ¾ -in bolts spaced 11 ¼ 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 keyed to the motor shaft. This pinion drives another gear whose axis is in the same xz plane. Determine the maximum shear and tensile forces on the mounting bolts based on 200 percent overload torque.

Does the direction of rotationmatter?
