Moments

1. Moment of force (Nm) = F (N) x d (m)

1.1. The distance is the perpendicular distance from the force to the pivot.

2. The tendency of a force to rotate an object about a pivot.

2.1. The pivot can be any point on the object in the case where it is not specified, need not always be the geometrical centre of the object.

4. Principles

4.1. No resultant force - total upward force = total downward force

4.2. No resultant moment - sum of clockwise moments = sum of anticlockwise moments

4.2.1. To determine whether a force is clockwise or anticlockwise, draw an arrow extending the force's arrow that points to the pivot.
