Two couples act on the frame shown in $($Figure $1).$

If $\backslash ($ d$=4\mathrm{.}8\backslash$mathrm$\{$ft$\}\backslash ),$ determine the resultant couple moment either by summing the moments of the two couples or resolving each force into $\backslash ($ x $\backslash )$ and $\backslash ($ y $\backslash )$ components and then summing the moments about $\backslash ($ A $\backslash )$ of all the force components.

Express your answer in pound$-$feet to three significant figures. Enter positive value if the moment is counterclockwise and negative value if the moment is clockwise.
