The T$-$beam cross$-$section shown has an effective depth of

$26\mathrm{.}46$ in$.,$ a distance from the extreme compression fiber to

the extreme tension layer of $27\mathrm{.}36$ in$.,$ and a neutral axis

depth of $6\mathrm{.}76$ in $.$ Material properties are $f_c^{\text{'}}=3000,$ and

$f_y=60,000$ psi. Reinforcement consists of #$4$ stirrups and $5-$

#$10$ bars as tension reinforcement. The nominal moment

capacity is approximately

a$)650$kips$-ft$

c$)750$kips$-ft$

b$)680$ kips$-$ft

d$)710$kips$-ft$

$b_w=14$ in
