Moments Of A Couple probably just something simple.

    1. The problem statement, all variables and given/known data

    If the couple has a magnitude of M, determine the magnitude F of the couple forces.
    Since this is an X-Y plane, I assumed the equation would simple just be M=Fd, where I know the moment, and just have to add the the the forces multiplied by their respective distances.

    3. The attempt at a solution

    My attempt was simple set it up like this.

    250 = F(3/5)(sqrt(17)) - F(4/5)(9)
    Mostly I just want some certification that this is either right or wrong and if it's wrong to be steered in the right direction with possibly a new answer.

    The moment between 2 || forces is going to be the ⊥ distance between their lines of action isn't it?

    I'm not certain that's what you found.
