The initial compressive force of a steel column can be determined by Euler's buckling formula. The column has the following properties. A = 9484 mm² Fy=345 MPa x = 164 x 106 mm² ly = 23 x 106 mm4 Proportional limit, f = 290 MPa The x-axis has an unbraced length of 10 m which is pinned at the top and fixed at the bottom with an k = 0.70. The y-axis has unbraced length of 5 m due to the bracing at the mid-height. Which of the following most nearly gives the axial force in the boom? Select the correct response: 104.62 kN 43.33 kN E = 200 GPa 94.75 KN 38.14 KN 2 Poln
