Anything to do with moments?

  1. Apr 29, 2010 #1
    Can anybody tell me what a couple is. From what i gather it is when two forces are equal, opposite and parallel.

    But but if 1 force is bigger than the other say a 2 and a 3N force could it be said that there is a couple of 2N forces ?

    Does it have anything to do with moments?

    Re: couple

    Draw yourself a force diagram showing what you have just described, with unequal forces.

    Now resolve horizontally and vertically.

    Does your diagram describe equilibrium?

    Does that answer your question?

    so i suppose it depends on the angle? but dont they have to be strictly parallel?
