Moment is defined as the product of the force (F) and the moment arm (d) The moment arm is perpendicular distance between line of action of force and center of moment. The direction of moment can be find with the help of right hand rule, that is put your hand towards the direction of force and fingers of your hands curls towards the direction of rotation of force exerted. I also calculate net moment at different points which makes you easy to understand.
