Rotation
If clockwise moments are positive, and the rotation of force F with respect to point A is counterclockwise, then the sign of the moment must be negative. The same case with other moments.

Why is the A ?? Its should be negative not positive?
Re: Rotation
In reply to Rotation by QIndustries13
The standard sign for moment is positive for counterclockwise rotation and negative for clockwise rotation. The solution here uses these standard sign notations. You may reverse the signs if you wish as long as you are consistent. It will be fine specially if you indicate your preferred sign in your solution.
