Equivalent Force couple system

4–111. The belt passing over the pulley is subjected to
forces F1 and F2, each having a magnitude of 40 N. F1 acts in
the -k direction. Replace these forces by an equivalent force
and couple moment at point A. Express the result in Cartesian
vector form. Set u = 0 so that F2 acts in the -j direction.

WARNING to all my Statics class peeps!!!! The final answer for the moment couple is incorrect. It should be {-12j + 12k} He wrote all the signs correctly in the cross product multiplication, but he multiplied (-1)(-.3)(-40) and got +12, which, of course, should have been -12
