Question
Why do spring balances show wrong readings after they have been used for a long time?
Solution
When spring balances have been used for a long time, elastic fatigue is developed. So, the spring balances will no longer show the right readings.
Note: Elastic fatigue is the property of a body to lose it's elastic property by repeated action of restoring and deforming force.
