A W$14$x$132$ section has been rolled from a new experimental steel, and data has been

obtained from a stub column compression test, where the initial length of the columnwas $12$ inches. A$.)$ Use the results from graph to develop a column strength curve $($for weak$-$axis buckling$)$ in terms of critical buckling stress $($Fcr$)$ vs$.$ normalized unbraced length $($Lc$/$ry$).$ Use the concept of tangent modulus $($Et$)$ and neglect imperfection effects. Plot for Lc$/$ry b$.)$ Use the results from problem A$.$ to develop a column strength curve $($for weak$-$axis buckling$)$ in terms of nominal strength $($Pn$)$ vs$.$ unbraced length $($Lc$).$ Plot for Lc ft$.$STRESS STRAIN CURVE
