QUESTION:

The turbine develops 150 kW of power, which is transmitted to the gears such that C receives 70% and D receives 30%. If the rotation of the 100-mm-diameter A-36 steel shaft is \(\omega=800 \mathrm{rev} / \mathrm{min}\), determine the absolute maximum shear stress in the shaft and the angle of twist of end E of the shaft relative to B. The journal bearing at E allows the shaft to turn freely about its axis.

ANSWER:

Step 1 of 6

The expression for the torque transmitted by the shaft is given by,

                                                             

Here, P is the power,  is the rotational speed of shaft in rpm.
