Question 40
Easy

Figure 1 shows a force of 120 N being applied to a spanner to turn a nut about pivot point O.

Diagram showing a horizontal spanner attached to a nut at pivot point O. A distance of 0.15 m is shown between pivot O and the end of the spanner where a downward vertical force of 120 N is applied.

Calculate the moment of the 120 N force about point O.

State the unit.

Use the equation:

moment=force×distance \text{moment} = \text{force} \times \text{distance} moment=force×distance
