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. 280 N 395 N 210 N 670 mm 670 mm 670 mm.

2/86 If the resultant of the loads shown passes through point B, determine the equivalent force-couple system at O. 45 kN 54 kN 1.2 m 0.9 m 0.9 m x- OB 18 kN
