Oscillators – The mass and spring oscillator
Force Constant of a Helical Spring Apparatus
Experiment
To determine the force constant (spring constant) of a helical spring by plotting a graph
between load and extension.
Principle
The experiment is based on Hooke's Law, which states that within the elastic limit of a spring,
the extension produced is directly proportional to the applied load.
Technical Specifications
1. Support stand with mounted millimeter scale.
2. Scale length: 25 cm.
3. Scale engraved on a plane mirror for parallax-free readings through reflected
illumination.
4. Scale mounted with elevation adjustment on a support rod.
5. Helical steel spring suspended from a hook above the scale.
6. Spring dimensions:
? Diameter: 1 cm
? Length (unstretched): 3 cm
7. Weight hanger provided for loading the spring.
8. Set of weights included.
9. Total weight: 1.3 kg.
10. Apparatus size: 54 × 14 × 7 cm.
