Problem #I. The section shown below is subjected to bending about an axis parallel to the $40-mm$ dimension of the aluminum plate. Assuming the brass and aluminum plates are securely bonded at their interfaces, determine:

I. The transformed section moment of inertia if the section is transformed to aluminum. Illustrate $($with dimensions$)$ the transformed section.

$2.$ The transformed section moment of inertia if the section is transformed to brass. Illustrate $($with dimensions$)$ the transformed section.

$3.$ Illustrate the normal strain $()$ and normal stress $()$ distributions for the section.

$E_{\text{a}\text{l}\text{u}\text{m}\text{i}\text{n}\text{u}\text{m}}=70$GPa

$E_{\text{b}\text{r}\text{a}\text{s}\text{s}}=105$GPa
