Abstract: This paper presents the relationship between parent and daughter spring constants measure and analyzed for three helical springs. The study employed one group pretest-post test experimental design with neither randomization nor control group. The three helical springs A, B and C used as experimental group were subjected to a pretest determination of their spring constant before they were each cut into a section equal to half of its original length (daughter spring). A post test determination of the spring constant in each of the daughter springs was done.
The study found out that the spring constant of parent springs A, B and C were; 43.8338 N/m, 10.0988 N/m and 12.2840 N/m respectively while as the daughter spring constants for A, B and C were 73.8149 N/m, 19.6200 N/m and 23.9443 N/m respectively.
The results of this study show that the spring constant of any spring when cut into half of its original length, is never constant but is in agreement with Thomas young`s theory.
