Figure $1($a$)$ and $($b$)$ show $2$ 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 majr 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.
