A technician tests a spring used in a loading-bay buffer. The spring has a length of 0.120 m when no force is applied.
The spring remains within its limit of proportionality throughout the test.
| Force in N\text{N}N | Length of spring in m\text{m}m |
|---|---|
| 0 | 0.120 |
| 2.0 | 0.112 |
| 4.0 | 0.104 |
| 6.0 | 0.091 |
| 8.0 | 0.088 |
| 10.0 | 0.080 |
Explain which measurement the technician should repeat. Calculate the expected length of the spring when this measurement is repeated.
