Force, Turning Effect and Equilibrium
1 markDifficulty: Easy
A spanner is used to loosen a nut. The turning effect is greatest when the force is applied:
- aclose to the nut, along the spanner
- bat the far end of the spanner, at right angles to it
- cat the far end of the spanner, along its length
- danywhere, since only the size of the force matters

Answer
at the far end of the spanner, at right angles to it
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
The moment is the force multiplied by the perpendicular distance from the pivot, so both the greatest distance and a right-angled direction are needed. A force along the spanner has no perpendicular distance at all and produces no turning effect.
