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!
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 …
(and I'm not following where you got -24Nm or 7.5Nm from
)

what do you get?
