Question 2 21 Marks A Strut With A Length Of 10 M And An I Cross Section With Cross Sectional Values Of 610 X 229 X 11 1 (26.6 KiB) Viewed 19 times

Question 2 [21 Marks] A strut with a length of 10 m and an I cross-section with cross-sectional values of 610 x 229 x 113 (mm x mm x kg/mm), is treated as being fixed on both ends when it buckles about its weaker axis and pinned on both ends when it buckles about its stronger axis. If it's elastic modulus is equal to 210 GPa, its yield stress 260 MPa and the Rankine constant for a strut with both ends fixed as 1/6400, calculate using the Euler and Rankine formulae, the least buckling load for the strut and state which of these two formulae is best for this case.
