·         1.23 recall and use the relationship between the moment of a force and its distance from the pivot: 

moment = force × perpendicular distance from the pivot

·        A moment is a turning force

·        It depends on the size of the force and the perpendicular distance from the pivot

M = F x d

 

M = moment (Nm)

F = force (N)

d = perpendicular distance from the pivot (m)

Worked example

Image001

M = F x d

M = 1 x 5

M = 5Nm
