Problem $2($Resistance of cross$-$section class $4$ members$)$

a$)$ Determine the cross$-$sectional compression resistance of the compression member $($Isection$)$ shown in Figure $2$a $($assume it is a very short column, i$.$e$.,$ there is no

reduction for Euler$-$type of buckling$).$ Assume that the flanges of the section are

connected to the web by fillet welds, with weld root measure a$=8$ mm$.$
