    I can seem to get the answer of 60N and 125mm from C

    Thank you for the help

    I actually do not really know how to solve the question.

    I now that there is two forces one clockwise and another anticlockwise and they both suppose to cancel each other out when I calculate the moment but for one I am getting -24Nm and the other 7.5Nm. After that I am not very sure what to do?

    Thank you

    hi zack7! :smile:
    no, there are three forces, you have to find a single force with the same total value (obviously, it's going to be 60N directly down the page), and you have to find the point on CD where that new 60 N has the same moment (about anywhere) as the total moment of all three original forces …

    what do you get? :smile:

    (and i'm not following where you got -24Nm or 7.5Nm from :confused:)
