Couple moment problems - Calculate the distance?

    Couple moment problems -- Calculate the distance?

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

    2. Relevant equations

    M = F x d

    3. The attempt at a solution

    M = Fxd
    20Nm = 35N*x
    x = 0.57m

    cos 30 deg = x/d
    d = x/cos 30 deg = 0.57m/cos 30 deg = 0.66m

    is this correct?

    Yes, I think that is correct. (I might have used a different variable besides 'x', so as not to confuse it with the x-axis direction specified in the diagram, but the final answer works out the same).
