(PP3) principle of moments

• verify the Principle of Moments using a suspended metre rule and attached weights
• the principle of moments states that when a body is balanced, the total clockwise moment about a point equals the total anticlockwise moment about the same point.
• Moment =force F x perpendicular distance from the pivot d.

  Moment = Fd
• Each time the ruler balances horizontally we can see from our results that, the anticlockwise moment about the pivot = the clockwise moment about the pivot.

  This verifies the Principal of Moments.
