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.

Power Transmission Elements

It is defined as the energy transfer from one location to another location. The energy will start moving from the energy generation source to the energy applied position to obtain the work output. From this method, a large amount of electric energy moves from the power station to various electrical substations.
