Problem $2(25$ points$)$

For an $M_u=6,600k-$in$,$ design a rectangular cross$-$section having $b=14in.$ and $h=26$ in$.$ such that

the strain in the tensile steel reinforcement is $0\mathrm{.}0065in./$in$.$ Select the bars and show that they fit in

the cross$-$section $($bar spacing, using #$4$ stirrups if needed$).$ Use $f_y=60$ksi and $f_c^{\text{'}}=4$ksi.
