A cantilever beam with $b=12$ in$.$ contains three #$7$ bars that are anchored in the column with standard $90$ hooks. $f_c=4,500($normal weight$)$ and $f_y=60,000.$ If the steel is stressed to $f_y$ at the face of the column check the following:

$($a$)$ Can the bars be anchored by hooks into the column? The clear cover to the side of the hook is $\frac{23}{4}$ in$.$ The clear cover to the bar extension beyond the bend is $2$ in$.$ The joint is enclosed by #$4$ ties at $6$ in$.$ o$.$c$.$

$($b$)$ Can the bars be developed in the beam? The bar ends $2$ in from the end of the beam. The beam has #$3$ double leg stirrups at $7\mathrm{.}5$ in$.$
