- A thin-walled rectangular tube has uniform thickness t and dimensions a x b to the median line of the cross section (see figure). How does the shear stress in the tube vary with the ratio = a/b if the total length Lmof the median line of the cross section and the torque T remain constant? From your results, show that the shear stress is smallest when the tube is square (ß = 1).The compound shaft is attached to a rigid wall at each end. For the bronze segment AB, the diameter is 68 mm and G = 34.84 GPa. For the steel segment BC, the diameter is 40 mm and G = 83.59 GPa.
