I understand that to find moment of force, we look at direction of force and perpendicular distance. In the diagram, O is the centre and pivot of the circular disc.
Would the anticlockwise moment at A be (30N x 4m)? I'm not sure if this is true, cos the distance 4m is only AB. It does not include O which is the pivot.
Should we resort to resolving the 30N force to 2 components at 5m (OA)?
(Clockwise moment is straightforward here, isn't it?)
