1.Select the lightest available W14 section for column tosupport the axial compression loads Pd=150k and Pl=200 k if KL =14ft and A572 grade 50 steel is used. Column is assumed to be inframe that is braced against side-sway. Use trial and error methodin which a KL/r value is estimated. Solution should have required areas calculated, trial section selected checked revised ifnecessary.

2.A W 12 x 50 is used as acolumn to support an axial load of 145 kips. The length is 20 feet,and the ends are pinned, without regard to load resistance factors.Investigate the member’s stability.
