Part A

If $d=7\mathrm{.}2ft,$ determine the resultant couple moment either by summing the moments of the two couples or resolving each force into $x$ and $y$ components and then summing the moments about $B$ of all the force components.

Express your answer in pound$-$feet to three significant figures. Assume the positive direction is counterclockwise.
