The segment AB of the steel torsion bar is a cylindrical tube of constant 2-mm wall thickness. Segment BC is a square tube with a constant wall thickness of 3 mm. The outer dimensions of the cross-sections are shown in the figure. The tubes are attached to a rigid bracket at B, which is loaded by a couple formed by the forces P = 17 kN. Determine the maximum shear stress in the shaft. Take G = 75 GPa. P 1.2m C 100 mm 100 mm t = 3 mm 1.2 m 80 mm B 300 mm A t = 2 mm Important reminder: The formulas derived for thin-walled tubes are just approximations. So, for the case of hollow circular tubes with constant thickness, you should still use Tc/J and TL/JG to solve for the shear stress and angle of twist, respectively.
