$9\mathrm{.}5-7$ The cantilever beam ACB shown in the figure has

flexural rigidity $EI=6\mathrm{.}1{10}^{6}N*m^2.$ Calculate the

downward deflections ${}_C$ and ${}_B$ at points $C$ and $B,$ respec$-$

tively, due to the simultaneous action of the moment of

$4kN*m$ applied at point $C$ and the concentrated load of

$16kN$ applied at the free end $B.$
