A spring is placed under load with weights. After the weights are taken away, the spring returns to its starting length. The spring is then placed under a larger load with heavier weights. When those weights are removed, the spring remains longer than its starting length. Which types of deformation are demonstrated by this experiment?
- Aboth elastic and plastic deformation
- Belastic deformation only
- Cneither elastic nor plastic deformation
- Dplastic deformation only
