An 9m long steel column is pinned at the top and fixed at the bottom. The column is provided with lateral support at every third point in the weak direction. The Euler critical load is Pc = (T^2 eI)(kL)^2 The properties of the column section: Ix = 178.1 x 10^6 mm^4 ly = 18.8 x 10^6 mm ^4 A = 8129 mm^2 a. What is the critical effective slenderness ratio b. Calculate the critical load Pc, in kN c. Determine the minimum length of the column for which the euler's formula is valid if the proportional limit of the steel used is 320 MPa.
