What is the moment of a force defined as?
Which conditions are needed for a beam to be in equilibrium?
The pivot must always be at the centre of the beam.
Complete the equation for a moment.
Moment = Force ×
Type the missing quantity (e.g. a distance).
Complete the paragraph.
The turning effect of a force is called a drop here. It is the product of the force and the drop here distance from the pivot.
