A. Using Euler formula, determine if the column fails by elastic or inelastic buckling if a W10x22 (A= 6.49 in2, Ix= 118in4, rx= 4.27 in, Iy=11.4in4 and ry= 1.33in) is used as a 15ft long pin-connected column, assuming the steel has a proportional limit of 36 ksi. B. Repeat part (a) if the length of the column is changed to 8 ft.

Question
A. Using Euler formula, determine if the column fails by elastic or inelastic
buckling if a W10x22 (A= 6.49 in2, Ix= 118in4, rx= 4.27 in, Iy=l1.4in4 and
ry= 1.33in) is used as a 15ft long pin-connected column, assuming the steel
has a proportional limit of 36 ksi.
B. Repeat part (a) if the length of the column is changed to 8 ft.
