$4\mathrm{.}108$ A $12-$m pole supports a horizontal cable $CD$ and is held by a ball

and socket at A and two cables $BE$ and $BF.$ Knowing that the ten$-$

sion in cable $CD$ is $14kN$ and assuming that $CD$ is parallel to the

$x$ axis $(=0),$ determine the tension in cables $BE$ and $BF$ and the

reaction at $A.$

$4\mathrm{.}109$ Solve Prob. $4\mathrm{.}108,$ assuming that cable CD forms an angle $=25$

with the vertical $xy$ plane.
