Question $(4)-(20\%$ :

A ${25}^{\text{'}}$ rectangular reinforced concrete beam with $b={12}^{\text{'}\text{'}},d={17}^{\text{'}\text{'}}$ and stirrups spacing $S=7^{\text{'}\text{'}}.$ If $f_c^{\text{'}}=4$ksi,$f_y=60$ksi, service $W_{D.L}=1\frac{k}{f}t$ and service $W_{LL}=2\frac{k}{f}t,$ solve questions $(11-15)?$
