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

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

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

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

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

6 One more! The beam has a weight of 30N, find force F. F d 1 =80cm d 2 =120cm

7 One more! F d 1 =80cm d 2 =120cm 30 N d 3 =60cm

1. Balance the ruler carefully at its midpoint. If necessary, you can add a blob of plasticine to one side until the ruler balances. 2. Then add weights.
