Document Summary
Resultants of a force and couple system. Further reduction of a force and couple system. Resultants of a force and couple system (section 4. 8) In a particular case where several forces and couple moments act on a body, you can move each force and its associated couple moment to a common point o . Now you can add all the forces and couple moments together and find one resultant force-couple moment pair. If the force system happens to lie in a 2-d plane (x-y), then the reduced equivalent system can be obtained using the following scalar equations: Further reduction of a force and couple system (section 4. 9) If the f r and m ro are perpendicular to each other, then the system can be further reduced to a single force, f r , by simply moving f r from o to p.
