The turbine develops 300 kw of power, which is transmitted to the gears such that both b and c receive an equal amount. if the rotation of the 100-mm-diameter a992 steel shaft is v = 600 rev> min., determine the absolute maximum shear stress in the shaft and the rotation of end d of the shaft relative to a. the journal bearing at d allows the shaft to turn freely about its axis.

Asolid cylinder is concentric with a straight pipe. the cylinder is 0.5 m long and has an outside diameter of 8 cm. the pipe has an inside diameter of 8.5 cm. the annulus between the cylinder ad the pipe contains stationary oil. the oil has a specific gravity of 0.92 and a kinematic viscosity of 5.57 x 10-4 m2/s. most nearly, what is the force needed to move the cylinder along the pipe at a constant velocity of 1 m/s?
