Thank you! I am glad to help :)

Thank you very clear.
One question, why are the forces not negative when you divide the -4 N*m by their respective distances?

[@LearningbyTeaching]

I canceled the negative from both sides of the equal sign.

@@LearningbyTeaching Ah because the clockwise moment and I brain farted! Thank you.

Glad to help!

I didn't understand one thing , if total moment is 4 so it should be equal to df+dP , why we equal them separately, 4 = df and 4 =dp ???
