### Step-by-Step Solution: 1. **Understanding the Spring Balance**: A spring balance is a device used to measure weight or force. It operates based on Hooke's Law, which states that the force exerted by a spring is directly proportional to the amount it is stretched or compressed. 2. **Continuous Usage**: When a spring balance is used repeatedly over time, the spring within the device undergoes continuous stretching and compressing. This repeated mechanical stress can affect the spring's properties. 3. **Loss of Elasticity**: With continuous use, the material of the spring can lose its elasticity. Elasticity is the ability of a material to return to its original shape after being deformed. If the spring loses its elasticity, it will not return to its original length after being stretched. ...
