A steel pipe column (E 5 210 GPa) with length L 5 4.25 m is constructed of circular tubing with outside diameter d2 5 90 mm and inner diameter d1 5 64 mm. The pipe column is fixed at the base and pinned at the top and may buckle in any direction. The Euler buckling load of the column is most nearly:
(A) 303 kN
(B) 560 kN
(C) 690 kN
(D) 720 kN
