A set of spur gears is employed to convey motion from an AC motor generating 80 horsepower at 3,000 revolutions per minute (rpm) to a milling machine operating at 1,600 rpm. Your tasks is to: a. Determine gear design parameters such as dimensions and materials used for pinion and gear. b. Develop a 3D model of the gears, incorporating the dimensions determined in part (a), along with the AC motor and milling machine, using Computer-Aided Design (CAD) software. c. Perform an analysis of the potential failure modes in the gear teeth.
