Calculations show that $2\mathrm{.}24i{n}^2$ of top reinforcement is required at the supports of the beam shown. Three #$8$ bars have been selected in $($:${?}^2\}.$ Are the $4ft\mathrm{.}6$ in embedment lengths shown satisfactory if $f_c^{\text{'}}=4,000$ psi and $f_y=60,000$ psi.? Bars are spaced $3$ in$.$ o$.$c$.$ with $3-$in side and top cover measured from the center of the bars. Use the full equation $25\mathrm{.}4\mathrm{.}2\mathrm{.}4$a with $K_{tr}=0.$
