Part of CCE has a steel column with AB on the first floor and BC on the second floor. The third floor load (P1) is 250 kN and the second

floor load (P2) is 500 kN. You may neglect the self-weight of the steel column. Find the internal axial forces in both columns by making cuts between A and B, and then Band C and applying static equilibrium.а. b. Plot the axial force diagram.
