# Does spring constant change with length

A spring is suspended from a rod and a mass is then attached. The length of the spring is measured at two positions: its original unstretched, equilibrium position (A) and its final stretched position (B). After calculating how far the spring was displaced from equilibrium at position B, a graph was plotted showing these two positions. Original.Assuming the Europa owner desires to cut two coils from the springs, the spring constant will be 1/9.5/11.5, or 1.21 times higher than the stock spring.
