A moment is...
a force measured in Newtons
a turning force measured in newton metres
a distance measured in metres
a time intervals measured in clicks
To calculate a turning effect of a spanner the force is multiplied by the length of the spanner
always - if the length of the spanner is equal to the distance from the fulcrum to the applied force
never - the length must be equal to the distance from the pivot to the fulcrum
if the length of the spanner is equal to the parallel distance from the pivot to the applied force
if the length of the spanner is equal to the perpendicular distance from the pivot to the applied force
Moment (Nm) =
Force (N) x distance (m)
Angular Force (N°) x distance (m)
Work done (J)
Force (N) x distance (s)
