design shear stirrups at the critical section using $2-$Leg #$4$ bar stirrups for a simply supported beam with a clearr span of $17$ feet. The loads consists of a uniformly distributed live load of $6\frac{k}{f}t$ and a concentratec live load of $10k$ at the midspan. Thickness of the beam $=25$ in$,$ depth $=23$ in$,$ width $=15$ in $.$ Flexural reinforement consists of $4-$#$9$ bars. Use the accurate$($long$)$ formula for calculating the shear capacity of concrete, $f^{\text{'}}c=4500,fy=60000ps*$Draw the shear diagram
