50 kN 5kN/m В C D A I 70 kN - 3 m 5m +2m W200 x 19.3 Draw the shear-bending moment diagram of the beam shown. Calculate the maximum normal stress due to bending. If the beam is made of aluminum alloy 6061-T6, state the beam is safe or not.

Please by using this formula   Thanks..

how did you know k=2.3? where did th evalue of 2.3 come from?
