Experiment -Testing the principle of moments

• What did you notice about the anticlockwise
  moment and the clockwise moment?

• When forces act in a different direction, yet
  still balance, the total turning effect in each
  direction will be the same sum of
  clockwise sum of anticlockwise
• moments moments
