A technician is testing a spring before it is fitted to a self-closing cupboard door. The spring hangs vertically from a clamp stand. A pointer fixed to the bottom of the spring rests against the scale of a vertical metre ruler. The technician applies known forces to the spring.
Describe two actions the technician should take when reading the position of the pointer.
Give one way the technician could prevent the clamp stand from tipping.
The technician records these readings.
| Force applied / N | Pointer reading / m |
|---|---|
| 0.0 | 0.160 |
| 5.0 | 0.210 |
Calculate the extension of the spring when the applied force is 5.0 N.
