Problem 2 (5 points) For the simply supported beam shown and its cross-section, and considering the values L, and t assigned for each student as in the table provided. Answer the following questions. (a) Locate the most critical point on the beam (ie 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, t(mm)=5.8 2 KN L(mm)=164 1 kN/m A B 78mm 4mm 1 | 58mm I 0.1m L - 0.1m
