Q5 The figure shows a shaft carrying three gears that rotates at 1150 rpm. Gear A delivers power to a mating gear that drives a mixer. Gear C delivers power 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, Material 1144 OQT 1300 GearA=10kw,Gear C=15kw.

Q5 The figure shows a shaft carrying three gears that rotates at 1150
rpm. Gear A delivers power to a mating gear that drives a mixer. Gear
C delivers power 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.
