Moment of a Couple
Two couples , one consisting of the forces F1 and –F1, the other of F2 and –F2, will have equal moment if F1d1= F2d21

Reduction of System of Force
Any force ‘F’ acting on a rigid body can be moved to an arbitrary point ‘O’provided that a couple is added whose moment is equal to the moment of Fabout ‘O’

Resolution of Force into Force at ‘O’ and a Couple
Any force ‘F’ acting on a rigid body can be moved to an arbitrary point ‘O’provided that a couple is added whose moment is equal to the moment of Fabout ‘O’
