$(6$ points$)$ Cables AB and CD$,$ both with a diameter d$=1*$cm$,$ are composed of $18-8$ cold$-$rolled stainless steel and suspend a structural steel T$\_($beam $)="$WT$102\backslash$times $13"$ from rigid supports in the ceiling. Considering self$-$weight only for the T$-$beam, the overall downward deflection of point G $($at the center of the beam$)$ including the deformation of cables AB and CD is closest to$...$

Note$($s$)/($H$)$ints:

neglect the self$-$weight of the cables

self$-$weight of the beam is in k$($g$)/($m$)$

assume cables AB and CD remain vertically aligned

and simply support the beam

consider vertical deformation for cables and beam
