PROBLEM 5. Segments AB and BC of the shaft have circular and square cross sections, respectively. If end A is subjected to a torque of T = 2 kN-m, determine the absolute maximum shear stress developed in the shaft and the angle of twist of end A. The shaft is made from A-36 steel (G = 75 GPa) and is fixed at C. Answer: 47.2 MPa, 0.820°

Step 1
The shaft is made of A-36 steel, which has a shear modulus (G) of 75 GPa. A torque (T) of 2 kN-m is applied at end A, and the shaft is fixed at end C. We need to find the absolute maximum shear stress developed in the shaft and the angle of twist at end A. Show moreā¦

The steel shaft is made from two segments: 12 mm AC has a diameter of 12 mm, and CB has a diameter of 25 mm (Figure 1). If it is fixed 125 mm at its ends A and B and subjected to a torque of 300 N.m at D, determine the maximum shear stress in the shaft. Use Gst = 75 GPa.
