Two foam packaging samples, P and Q, were compressed between two flat plates. The thickness of each sample was measured in the direction of compression before the force was applied and after the force was removed.
| Sample | Thickness before compression (mm) | Thickness after force is removed (mm) |
|---|---|---|
| P | 18.0 | 16.5 |
| Q | 18.0 | 18.0 |
What do the results show about how each sample was deformed?
Sample P was deformed inelastically and sample Q was deformed elastically.
Both sample P and sample Q were deformed inelastically by the compression.
Both sample P and sample Q were deformed elastically by the compression.
Sample P was deformed elastically and sample Q was deformed inelastically.
