3. A 5.0 meter tall steel column with a rectangular cross section of 100mm by 80mm has fixed ends and is subjected to a vertical load P = 500kN. Using a safety factor of n = 2.5, let oyp = 280 MPa, E = 200 GPa, determine (a) the critical load and critical Euler stress, and (b) based on part (a) will the column fail by yielding or buckling? How do you know?
