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. 170 N 310 N 690 mm 690 mm 270 N 690 mm Answers: Force-couple system at A. The force is positive if to the right, and the couple is positive if counterclockwise. R = i M = i Single resultant force. d = i N N-m mm
