Replace the three forces shown by an equivalent force-couple system at point A. If the forces are replaced by a single resultant force, determine the distance d below point A to its line of action. 130 N 410 mm 410 mm 110 N 410 mm 250 N Answers: Force-couple system at A. The force is positive if to the right, and the couple is positive if counterclockwise. R = i N M = i N•m Single resultant force. d = i mm
