Example: The solid steel shaft AC has a diameter of 25 mm and is supported by smooth bearings at D and E. It is coupled to a motor at C, which delivers 3 kW of power to the shaft while it is turning at 50 rev/s. If gears A and B remove 1 kW and 2 kW, respectively, determine the maximum shear stress developed in the shaft within regions AB and BC. The shaft is free to turn in its support bearings D and E.

Example: Compute the value of stress throughout the shaft
Example: The 150-mm-diameter shaft is supported by a smooth journal bearing at E and a smooth thrust bearing at F. Determine the maximum shear stress developed in each segment of the shaft.
J = r^4 /2 = d^4 /
A torque of magnitudeT = 8 kip.in is applied atD as shown. Knowing that the diameter of shaftAB is 2.25 mm and that the diameter of shaftCD is 1.75 mm, determine the maximum shearing stress in (a) shaftAB, (b) shaft CD. The radius of gear C and B are 1.6 in and 4 in. respectively.
