An aluminum alloy (E = 72.0 GPa) column has the cross section shown in Figure P12.19. It has a length of 9.00 m and is clamped at each end. A support at midlength of the column prevents deflection in the x direction but does not prevent rotation of the section nor deflection in the y direction.

a. Determine the buckling load.
b. What is the minimum proportional limit for the column to buckle elastically?
