Problem 3
The gear system shown below has a motor supplying 38 kW at 340 rpm to gear
A. Assume the following information:
• Shaft (1) is a solid 45-mm-diameter aluminum [G= 22 GPa] shaft with a length of L₁ = 1230 mm.
• Shaft (2) is a solid steel [G = 75 GPa] shaft with a length of L₂ = 700 mm.
• Shafts (1) and (2) are connected at flange C, and the bearings shown permit free rotation of the
shaft.
• Assume NÃ=29 teeth and NB=71 teeth.
