Prob 3. The composite beam shown below is made out of a wood beam $(E=2,000\mathrm{ksi})$ reinforced with a two shorter steel plates ( $E=29,000\mathrm{ksi}$ ) on the sides, as shown below. The dimensions of the beam are shown below (all in in). (A) Draw the V \& $M$ diagrams and determine the maximum moment, $M_{\max }$. (B) Determine the stress at top/bottom of wood and top/bottom of steel. (C) Sketch the bending stress and strain distribution over the height of the beam (over the wood and over the steel), at the point of maximum moment.
