Problem 2 For the simply supported beam shown and its cross-section, and considering the values L = 139 mm, and t = 7.05 mm. Answer the following questions. (a) Locate the most critical point on the beam (i.e what is the distance from point A, and where exactly on the cross section). (b) Draw shear moment diagrams and perform complete analysis for expected points to get the point with the maximum principal stresses and the maximum shear stress and draw the oriented elements for those stresses. 2 kN 1 kN/m B 78mm I 4mm -0.1m L 0.1m, 58mm -
