C$.$ For questions $9$ through $12,$ consider the beam below, supported with a fixed end at $A.$ It is loaded with two concentrated loads, as shown., i$.$e$.EI=$ constant.

$9.$ Compute the magnitude of the reactive moment at $A.$

$($a$)PL$

$($b$)2PL$

$($c$)3PL$

$($d$)4PL$

$10.$ Calculate the internal moment at $C.$

$($a$)-PL$

$($b$)-P\frac{L}{6}$

$($c$)-P\frac{L}{4}$

$($d$)-P\frac{L}{3}$

$11.$ Calculate the downward deflection at $C.$

$($a$)7P\frac{L^3}{162}EI$

$($b$)5P\frac{L^3}{81}EI$

$(4)4P\frac{L^3}{27}EI$

$($d$)7P\frac{L^3}{9}EI$

$12.$ Calculate the deflection at $D$ in kilonewton$-$meters $\frac{{?}^3}{E}$I, if $P=1kN$ and $L=3m.$

$($a$)\frac{2\mathrm{.}5}{E}I$

$($b$)\frac{3}{E}I$

$($c$)\frac{3\mathrm{.}5}{E}I$

$($d$)\frac{4}{E}$I
