Last updated: 18 October 2026
Key Features
- Metal support pillar on a stable base.
- Graduated scale in millimetres and centimetres with an adjustable zero point.
- Steel tension springs of consistent wire diameter.
- Stainless steel mass hanger with a slotted weight set.
- Anti-parallax pointer for reading the extension.
Technical Specifications
| Specification | Value |
|---|---|
| Support | Metal pillar on a stable base |
| Scale | Graduated in mm and cm, adjustable zero |
| Springs | Steel tension springs, consistent wire diameter |
| Loading | Stainless steel mass hanger with slotted weights |
| Pointer | Anti-parallax |
How It Is Used
A spring is hung from the pillar, the pointer is set to zero, and slotted weights are added to the hanger one at a time. Students read the extension for each load, plot force against extension and find the spring constant k from the straight-line part of the graph, noting where the limit of proportionality is reached.
Frequently Asked Questions
What comes with the Hooke’s Law Apparatus?
A metal support pillar with a mm/cm scale, steel tension springs, a stainless steel mass hanger with slotted weights and an anti-parallax pointer.
How is the spring constant found with the Hooke’s Law Apparatus?
Load the hanger in steps, record the extension on the scale each time and plot force against extension; the gradient of the straight section gives k.
