Moments

• A moment is the measure of the turning effect on a body and is defined as: $Moment\ \left(Nm\right)\ =$$\ 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.
