10-50. The turbine develops 150 kW of power, which is
transmitted to the gears such that both C and D receive an
equal amount. If the rotation of the 100-mm-diameter A-36
steel shaft is w = 500 rev/min., determine the absolute
maximum shear stress in the shaft and the rotation of end B
of the shaft relative to E. The journal bearing at E allows
the shaft to turn freely about its axis.
