Figure shows a shaft carrying three pulleys that rotates at 1750 rpm. Pulley A delivers 15 kW to a mating pulley that drives a fan. Pulley C delivers 20 kW to a different mating pulley that drives a conveyor. All power comes into the shaft through pulley B. Considering only torsion, compute the shearing stress in each part of the shaft. Consider stress concentrations.
