An I-shape SHORT column is subjected to an eccentric compressive load P of 50 kN as shown in Figure Q3a. Find the maximum compressive and tensile stresses in the section. (12 marks) Another steel LONG column with circular hollow section and uniform thickness is subjected to a concentric axial load P. The column has a fixed support at A and free end at B as shown in Figure Q3b. The height of column is 4 m. The outer diameter (D) is 200 mm and the inner diameter (d) is 170 mm. The elastic modulus (E) of steel is 205 kN/mm² and the yield stress (o,) is 355 N/mm²¹. Given the effective length factor K is 2.0. Determine the allowable load that the column can support if the factor of safety (n) is taken to be 2.5 under compression.
