Spring Stand S-IW　C15-4408

This stand measures the extension of the spring when the number of weights is changed.
The attached spring extension indicator weight has a line that makes it easy to measure the extension and reduces the effect of the initial spring tension.

NARIKA

Spring Elongation Experiment Set B-IW　C15-4409

You can experiment with the extension of the spring when the weight is applied and the difference in the extension of the two types of springs.
The attached spring extension indicator weight has a line that makes it easy to measure the extension and reduces the effect of the initial spring tension.

NARIKA

Spring pendulum experiment set　C15-4422

It is used to verify Hooke's law and to verify the period of the spring pendulum.
The spring excludes the initial tension, so the load and elongation are correctly proportional in the hook experiment.
