MOMENTS
O
F
dMoment of F about O = Fd
Anticlockwise moments are taken as positive
Units = Nm
If a rigid body is in equilibrium the resultant force is 0 and the total moment about any point is 0.
When a rod resting on two supports is about a pivot about one of the supports, the reaction at the other support is 0.
