Figure shows a shaft carrying three gears that rotates at 1150 rpm. Gear A delivers 20 kW to a mating gear that drives a mixer. Gear C delivers 12 kW to a different mating gear that drives a circular saw. All power comes into the shaft through gear B. Considering only torsion, compute the shearing stress in each part of the shaft. Consider stress concentrations.
