Quick Answer: The K Constant Spring Apparatus is a mechanics apparatus for determining the spring constant k, verifying Hooke’s law and studying how a spring’s extension relates to the applied force.
Last updated: October 2026
Key Features
Determines the spring constant, commonly written as k.
Supports Hooke’s law experiments with load and extension readings.
Helps students plot force-extension graphs from their data.
Covers elasticity, restoring force, proportional limit and deformation.
About This Product
The initial pointer or scale reading is taken with no load. Known loads are then added, and the spring is allowed to come to rest before each extension is recorded. Repeating this with increasing masses gives a set of readings from which the spring constant is calculated using the gradient of the force-extension graph. Weights are added and removed slowly to prevent sudden release or permanent deformation. Besides buyers across India, the K Constant Spring Apparatus can be exported to institutions in São Tomé and Príncipe, Costa Rica, Uganda, Bolivia and South Africa.
Frequently Asked Questions
Q1. How is the spring constant calculated? Force is plotted against extension from the recorded readings, and the spring constant is taken from the gradient of that graph.
