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 100 mm² ly = 23 x 100 mm Proportional limit, fs = 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. Determine the critical buckling load for the boom. E = 200 GPa Select the correct response: 189.50 KN

Question
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, fs = 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. Determine the critical buckling load for the boom. Select the correct response: 189.50 KN 53.91 kN E = 200 GPa 88.83 kN 158.31 kN
