Key Features
- Set of interchangeable steel springs with different spring constants.
- Rigid metal support rod on a heavy cast-iron base.
- Vertical scale in mm and cm with an adjustable zero index.
- Stainless steel mass hanger with slotted weights.
- Anti-parallax pointer for steady equilibrium readings.
Technical Specifications
| Specification | Value |
|---|---|
| Support | Rigid metal rod, heavy cast-iron base |
| Scale | Vertical, mm/cm, adjustable zero index |
| Springs | Interchangeable steel springs, varying k |
| Loading | Stainless steel mass hanger with slotted weights |
| Pointer | Anti-parallax |
How It Is Used
For the static method, weights are added and the extension read on the scale to find k from force over extension. For the dynamic method, the loaded spring is set oscillating vertically and its period timed; plotting the square of the period against mass gives k from T = 2π√(m/k). Swapping springs lets results be compared.
Frequently Asked Questions
Can the K Constant Spring Apparatus be used for oscillation experiments?
Yes. Besides the static extension method, the loaded spring can be set into vertical oscillation and its period timed to find k.
Does the K Constant Spring Apparatus include more than one spring?
Yes. It has a set of interchangeable steel springs with different spring constants.
