QUESTION 4 A horizontal cantilever beam \( \mathrm{ABC}, 4 \mathrm{~m} \) long, fix at C , has the section shown in Figure 3. The beam carries a concentrated load of 2 kN at its free end (A) and a uniformly distributed load of \( 1 \mathrm{kN} / \mathrm{m} \) between B and \( \mathrm{C} ; \mathrm{AB}=1 \mathrm{~m} \) and \( \mathrm{BC}=3 \mathrm{~m} \). (40 Marks) a) Determine the maximum stresses in tension and compression. b) Determine the shear stresses at the top of the cross-section; in the intersection point between the flange and the web and in the neutral axis.
