Q$2.$ Design a rectangular single reinforced concrete beam section $($i$.$e$.,$ select $b,d,$ h $,$ and the required tension reinforcement$)$ at midspan for the bridge simply supported rectangular beam that supports a service dead load $W_D$ of $(7\mathrm{.}5k\frac{N}{m})$ excluding the self$-$weight, and a concentrated service live load from the truck $P_L$ of $(35kN).$ The beam is exposed to weather, have $10$ stirrups for shear reinforcement and the maximum aggregate size is $25$ mm $.$ Do the final drafting and check the spacing. $fy=350$MPa and $f^{\text{'}}c=30$MPa,$L=7\mathrm{.}5m$
