Hooke's Law Spring Set

Set of five springs, each with a different spring constant, for in-depth investigations of Hooke’s law experiments. Springs range from 8 to 10 mm diameter and 58 to 66 mm length (including end loops).
The five spring constants and corresponding weight limits are:
10g/cm & 100g
20g/cm & 225g
50g/cm & 550g
100g/cm & 1100g
200g/cm & 2200g
