- Determine the moment of the force F about point A in terms of F and d. Use (a) the scalar method; and (b) the vector method.arrow_forwardThe two forces of magnitude F=30kN form a couple. Determine the corresponding couple-vector.arrow_forwardWhen the three forces are replaced by an equivalent force-couple system with the force at point O, the couple vector CR is directed parallel to the x-axis. Determine F and the resultant force-couple system.arrow_forward
