A column has the cross section shown in Fig. P.14.25 and carries a compressive load P parallel to its longitudinal axis. If the failure stresses of the material of the column are 4 and 22 N/mm² in simple tension and compression, respectively, determine the maximum allowable value of P using the maximum normal stress theory. Ans. 634.9 kN.
