Moments

Cards (4)

  • A moment is the measure of the turning effect on a body and is defined as: Moment (Nm) =Moment\ \left(Nm\right)\ = Force (N) x Perpendicular distance from Pivot (m)\ Force\ \left(N\right)\ x\ Perpendicular\ dis\tan ce\ from\ Pivot\ \left(m\right)
  • Due to the moment, increasing force or distance from the pivot increases the moment of a force
  • Levers are force magnifiers because increasing force or distance from the pivot increases the moment of a force
  • In equilibrium, clockwise moment = anticlockwise moment there is no resultant force acting on the body.
