Replace with equivalent force-couple system?? My book has one page on this and I do not understand what they want... Please see attached picture for problems.. First one, left side, says replace the 5KN force with an equivalent force-couple system at O. and The second one says to replace the 500N force with a equivalent force-couple system at B. Thanks a lot
Re: Replace with equivalent force-couple system?? I think what you want is C = rXF where r is the vector from the point in interest to the point where the force acts and F is the applied force vector. C = r_x*F_y - r_y*F_x See, "What is a couple?"
