Turning Forces and Centre of Mass

A moment is the turning effect of a force

Moment (Nm) = Force (N) x Perpendicular Distance (m)

  • The force on the spanner causes a turning effect or moment on the nut
  • A larger force would mean a larger moment
  • Using a longer spanner the same force can exert a larger moment because the distance from the pivot is greater
  • To get the maximum moment you need to push at right angles (perpendicular) to the spanner
  • Pushing at any other…
