A structural steel member of yield stress equal 350 MPa is used as a compression member (strut). The buckling stress according to Rankine & Gordon equation for the member (oc) was calculated and found to be 290 MPa. 1.1 Calculate the slenderness ratio if the Young's Modulus of the material (E) is 200 GPa. Take Rankine constant as [9] T²E 1.2 Calculate the radius of gyration (r) if the effective length (le) is 6000 mm. [3] 1.3 Calculate the second moment of area (I) of the section of the member if the cross- sectional area is 9.741x10-³ mm². [2] 1.4 If Euler equation is used to determine the buckling stress of this member, what would be the stress and the load to produce the stress?
