Draw the Shear Force Diagram $($SFD$)$ and Bending Moment Diagram $($BMD$)$ for the beam ACB $($use g $=$

$10$ m$/$s$2).$ If the beam has a composite section made of two brass strips $($Eb $=105$ GPa$)$ securely bonded to

an aluminum core $($Ea $=70$ GPa$),$ determine and draw the normal stress distribution of the composite

cross section corresponding to the point G located at $0\mathrm{.}5$ m to the right of point C$.$ Then, indicate the

maximum normal stresses in brass and aluminum.
