Question

If you want to loosen a tight nut with a spanner, which action would be most effective?

Options

• Using a longer spanner with the same force

• Applying the same force closer to the nut

• Using a shorter spanner with the same force

• Pulling the spanner directly away from the nut

Answer 1

Using a longer spanner with the same force

Explanation:

A longer spanner increases the distance 'r' from the axis of rotation, which increases the torque and makes loosening the nut easier.
