The second beam shown below $($top in compression, bottom in tension$).$ Assume normal weight concrete with strength $\backslash ($ f$\_\{$c$\}^\{\backslash$prime$\}=6,000\backslash$mathrm$\{$psi$\}\backslash )$ and max aggregate size of $\backslash (3/4\backslash )".$ Assume epoxy$-$coated Grade $60$ steel. The beam is exposed to weather. The beam design requires you to place $\backslash$#$3$ stirrups and six $\backslash$#$7$ bars in the section. You must satisfy all ACI $318-19$ rebar detail and spacing requirements. $[2$ points total$]$

a$.$ Place the designated bars in the cross section to maximize the depth $\backslash ($ d $\backslash )$ to the centroid of the tension steel. Then draw $($to$-$scale$)$ and dimension the cross section showing at least the following information $[1\mathrm{.}5$ points$]$:

i$.$ Depth $\backslash ($ d $\backslash ),$ width $\backslash ($ b $\backslash ),$ and total section height $\backslash ($ h $\backslash )$

ii$.$ Distance from bottom of section up to the center of each steel layer

iii. Smallest horizontal clear spacing between two longitudinal bars

b$.$ Compute the development length of the epoxy$-$coated $\backslash$#$7$ bars. $[0\mathrm{.}5$ points$]$

Hint: Note that the epoxy$-$coating development length factor depends on the clear cover and clear spacing of the bars. It's either $1\mathrm{.}2$ or $1\mathrm{.}5$; make sure you use the correct factor.
