A mechanic uses a spanner to tighten a nut on a car engine.

The force, FFF, applied by the mechanic is 12.0 N.
The moment of this force about the pivot is 3.6 N m.
Calculate the perpendicular distance, ddd, from the pivot to the line of action of the force. Use the equation:
moment of a force=force×distance \text{moment of a force} = \text{force} \times \text{distance} moment of a force=force×distance
