Question:

Select a steel wide-flange column of nominal depth 250 mm. (W 250 shape) to support an axial load P = 800 kN (see figure). The column has pinned ends and length L = 4.25 m. Assume E = 200 GPa and (Y = 250 MPa. (The selection of columns is limited to those listed in Table E-1(b), Appendix E.)
