2. Shear stress distribution along thin walled structures (4pts). The transversal shear force on each cross section is V. The coordinate system is indicated at the right of the following figure. For each of the following two cross-sections in orange color, a) Sketch the shear stress distribution along the thin-wall directions (stress is also in wall direction). b) Indicate which stress component you have sketched for each segment of the wall, Txor ? c) Indicate if the distribution is linear or quadratic. Use the rough size of the arrows to indicate the magnitude. xy yz I Z Two types, of cross-sections p (positive x- direction pointing toward you)
