A simply supported, rectangular, reinforced concrete beam with d $=24$ in$.,$ b $=15$ in$.$ and L $=28$ ft supports a uniformly distributed design load wu $=7\mathrm{.}5$ kips$/$ft $($which also includes the self$-$weight$).$ Design the entire beam against shear, per ACI $318.$ In your design, identify the portions of the beam requiring no stirrups and only the minimum reinforcement. As a final step of your design, draw the design shear force demand diagram and the design shear force capacity diagram on the same graph, and ensure that the capacity exceeds the demand.

Clearly show your stirrups over the length of the beam in a drawing$/$sketch$.$ Assume normal weight

concrete of compressive strength of $4$ ksi, and steel conforming to ASTM A$615$ Gr$.60.$
