Figure $1($a$)$ and $($b$)$ shows $2$ non$-$standard sections, a Z$-$section and an I$-$section respectively.

$($i$)$ Given that the sections shown in Figure $1$ are for beams that bend about the major axis,

determine the shape factor of each section.

$($ii$)$ If the I$-$section shown in Figure $1($b$)$ is oriented so that it bends about the minor axis,

determine the corresponding shape factor.
