ECQ $1)$

a$)$ Determine the distance $\frac{?}{\text{b}\text{a}\text{r}}(y),$ which locates the centroidal axis $x^{\text{'}},$ for the cross$-$sectional area of the beam shown. Use the given $x,y$ coordinate system shown in the figure to calculate your answer.

b$)$ Determine the Moment of Inertia of the beam's crosssectional area about the centroidal $x^{\text{'}}$ axis shown in figure. Use previous question to locate the centroidal $x^{\text{'}}$ axis.
