An elastic rubber buffer is compressed in a testing machine. The table shows how the compression changes as the force is increased.
| Force in N | Compression in mm |
|---|---|
| 0 | 0 |
| 100 | 2 |
| 200 | 4 |
| 300 | 6 |
| 400 | 9 |
| 500 | 13 |
| 600 | 18 |
What does the pattern above 300 N show?
The buffer becomes stiffer because each 100 N increase produces a larger compression.
The buffer has become inelastically deformed once the force reaches 300 N.
Each 100 N increase produces the same increase in compression.
Each 100 N increase produces a larger increase in compression.
