Sometimes more than one force acts on the same side of the pivot. Their overall turning effect is easy to work out.
The 2 N force has a moment of 2 × 0·2 m = 0·4 Nm clockwise.
Their combined moment = 0·4 Nm + 2·5 Nm = 2·9 Nm clockwise. Moments can just be added, but they must act in the same direction.
