A column of rectangular cross-section is made of steel with Sy = 380 MPa and E207 GPa and subjected to an axial compressive force P. Both ends of the column are pin-pin (rounded) in Plane A, and fixed-fixed in Plane B. A) Determine the ratio of (b/e) for equal buckling load in either plane. B) If P= 15 kN and n-3, determine the dimensions of the cross-section. ai: 24 0.8 m Plane-A en Plane-B
