F$\_(1)=7\mathrm{.}30$lb on the server's hand. If l$\_(1)=1\mathrm{.}35$ft

$,$ l$\_(2)=1\mathrm{.}10$ft$,$l$\_(3)=0\mathrm{.}200$ft$,\backslash$alpha $\_(1)=165\backslash$deg $,$ and $\backslash$alpha $\_(2)=120\backslash$deg $,$ what is the moment of force about the

shoulder joint at point A $?$ Assume that moments acting in the counterclockwise direction about

point A are positive whereas moments acting in the clockwise direction are negative.

Express your answer numerically in pound$-$feet to three significant figures.
