An aluminum column with a length of L and a rectangular cross-section has a fixed end B and supports a centric load at A. Two smooth and rounded fixed plates restrain end a from moving in one of the vertical planes of symmetry of the column but allow it to move in the other plane. (a) Determine the ratio a/b of the two sides of the cross section corresponding to the most efficient design against buckling. (b) Design the most efficient cross section for the column, knowing that L = 20in., E=10.1 x 10^6 psi, P = 5kips, and a factor of safety of 2.5 is required. Now, replace the pinned boundary condition on top with a fixed boundary condition. You otherwise leave all other aspects of the problem unchanged.
