- Description
Description
The PSSC helical steel spring kit is a simple, hands-on set for exploring Hooke’s law using known masses and a coil spring. It includes a plated steel 1 kg mass and 0.5 kg mass, plus a suitable spring with an eye at each end for easy suspension. By hanging the spring from a retort stand and applying the masses singly or together, students can observe extension under load and test proportionality between force and extension.
Measurements are taken using a rule or tape measure, supporting straightforward force–extension recording and graphing in classroom mechanics practicals. For higher accuracy in calculated forces, the masses can be weighed to confirm their true mass before running the experiment.
FAQs
Q: What is included in the kit?
