Answer 1

Answer:

Please mark me as brainest answer.

Explanation:

Because the longer the spanner is , the more is the perpendicular distance between the axis of spanner through which it rotates and the distance of your hand. And when perpendicular distance is more, less force is required. Try using the spanner by holding it with ur hand kept near the nut.
