  1. 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 What did you notice about the anticlockwise moment and the clockwise moment? Experiment -Testing the principle of moments

  2. Problem 1 - Find force F Mini white board activity with large moments apparatus 0.90m 0.30m F 60N

  3. Problem 2 - Find force F F 10cm 20cm 45N

  4. Problem 3 - Find distance d d 0.60m 20N 30N 44N 0.20m

  5. d 10N 20cm 40cm 20N 70N • Problem 4 - Find distance d

  6. F d1=80cm d2=120cm One more! The beam has a weight of 30N, find force F.

  7. F d1=80cm d2=120cm One more! 30 N d3=60cm
