A control dial turns about a central pivot. Its straight handle extends horizontally to the right. Two forces act at right angles to the handle.
| Force | Direction | Distance from pivot |
|---|---|---|
| 18 N | Downwards | 0.20 m |
| 10 N | Upwards | 0.50 m |
Calculate the resultant moment about the pivot and state its direction.
