Problem $1$

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

$10\frac{m}{s^2}).$ If the beam has a composite section made of two brass strips $(\{$:$E_b=105$GPa$)$ securely bonded to

an aluminum core $(\{$:$E_a=70$GPa$),$ determine and draw the normal stress distribution of the composite

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

maximum normal stresses in brass and aluminum.
