Determine $\frac{?}{\text{b}\text{a}\text{r}}(y)$ which locates the centroid $C$ of the cross$-$sectional area of the wing channel.

Consider the wing channel in $($Figure $1)$ with $h=4\mathrm{.}6in.$ Neglect the effect of rounded corners. The material has a uniform thickness of $0\mathrm{.}5$ in $.$
