Problem #$4$: Link $BD$ is made of brass $)$ and has a cross$-$sectional area of

$200m{m}^2.$ Link $CE$ is made of aluminum $)$ and has a cross$-$sectional area of

$300m{m}^2.$ Knowing that they support rigid member ABC, sketch the deflected shape

of the member ABC and based on the geometry if the deflected shape, relate the

displacements at A and $B$ to the displacement at $C.$
