The beam cross$-$section shown below spans $24ft.$ from simple supports. Compute the

maximum compression stress in the concrete and tension stress in the steel reinforcement

under the action of the beam self$-$weight plus a superimposed uniform load of $425lb\frac{s}{f}t$ along

the entire span. Material strengths are $f_c^{\text{'}}=6,000$ psi and $f_y=60,000$ psi. All dimensions are

inches.
