We have seen that more than one moment can act in one direction. We may sometimes wish to work out how these could be balanced.
At what distance must the 6 N force act to balance the other forces?
When balanced: sum of clockwise moments = sum of anticlockwise moments
It is easily shown that the clockwise moment = 3.0 Nm. To balance this, the anticlockwise moment must also be 3·0 Nm. So:
6 × d = 3·0
