4.11 Consider a thin-walled square section with the cross-section shown in Figure 4.37a. The wall thickness is t = 0.3 cm and the average side length is 15 cm. Find the torsion constant. If the section is now cut open (4.28b), determine the new torsion constant. Find the shear stress distributions if 4 = 2°/m. (a) (b) 0.3 cm V 个 15 cm
