Answer d and e only
Transcribed Image Text:AWT205 x 30 structural steel section (see Appendix B for cross-sectional properties) is used for a 6.8 m column. Assume pinned
connections at each end of the column. Determine:
(a) the slenderness ratio.
(b) the Euler buckling load. Use E- 200 GPa for the steel.
(c) the axial stress in the column when the Euler load is applied.
Part 1
Use Appendix B to look up the cross-sectional area, the area moment of inertia, and the radius of gyration for a WT205 x 30
structural steel section.
