A steel pipe column (E 5 190 GPa, ? 5 14 3 1026/°C, d2 5 82 mm, and d1 = 70 mm) of length L 5 4.25 m is subjected to a temperature increase DT. The column is pinned at the top and fixed at the bottom. The tem- perature increase at which the column will buckle is approximately:
(A) 36 8C
(B) 42 8C
(C) 54 8C
(D) 58 8C
(D) 58 8C
