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. 120 N 570 mm 570 mm 290 N 570 mm 265 N Answers: Force-couple system at A. The force is positive if to the right, and the couple is positive if counterclockwise. R = 95 N M = i 33.76 N.m Single resultant force. d = 355.3 mm
