Design the beam below for shear. Sketch the shear for diagram and show the concrete shear strength, Vu at d, and the point where stirrups are no longer required. If stirrups are required, calculate the shear at one foot intervals to determine the spacing until stirrups are no longer required; determine the point they are no longer required, and sketch the stirrup locations. $(35\mathrm{pts})$ $\begin{array}{l}{f}_c=3,500\mathrm{psi}\\ f_y=60,000\mathrm{psi}\\ \text{ WoL }=1,400\text{ plf (not including self-wt.) }\\ \text{ Wu=4,200 plf }\\ 11/{\text{ s. }}^{?}\text{ cover }\\ \#3\text{ Stirrups, if needed }\\ \text{ Support width }=12^{?}\end{array}$
