Determine ${}_t,,$ and $M_n$ for the section shown below. Also determine the minimum area of steel for

this section and check if the steel area provided in the section meets the limit$.$ Note that there is an

opening $6$ wide by $8"$ deep which is symmetrically located within the section as shown in the figure.

Also determine the maximum area of steel based on $c_{\text{m}\text{a}\text{x}}=3\frac{d_t}{7}$

$f_y=60,000F$

$f_c^{\text{'}}=3,500F$
