Learning Goal: To replace force-couple systems with an equivalent force by specifying the magnitude and direction of the equivalent force and the location where the force needs to be applied. Certain force-couple systems can be replaced by a single force. The requirement is that the lines of action of the resultant force, FR, and the resultant couple moment, (MR)o, are perpendicular to each other. This is equivalent to saying the following types of force systems can be simplified to a single force: . Concurrent force system: This is a system where all the lines of action of the applied forces intersect at a common point. Because this means all the Figure d₂ F3 d < d 3 of 3
