A rectangular beam has width of $12$ in and effective depth of $22\mathrm{.}5$ in to the centroid of tension ateel hars. Tension reinforcement consists of fitle bars in two rows; compression rein forcement consists of $2$ ill bars with a cover of $2\mathrm{.}5$ in$.$ Compute the design moment strength of the beam soction, if $f^{\text{'}\text{'}}=4ks,$ and $f_y=60$ksi. Ese ISD method.

A $20$ fl lone simply supported beam has fo carry a factored moment of $132k-1t$ at mid$-$span. Demonstrate the flexural design of the beam if$,f^{**}=4$ksi, and $f_y=60$ksi. Use USD method.
