Question
A helical compression spring is wound using 0.12-in-diameter phosphor-bronze B159 wire. The spring index
C = 10 and the total number of coils is N = 14. You may assume that the spring has both ends squared and
ground and is supported between fixed ends. Also, Sgy = 0.45 · Sut-
a. Estimate the spring rate.
b. Estimate the static load corresponding to the yield strength.
c. What should the free length of the spring be to ensure that when it is compressed solid the torsional
stress does not exceed the yield strength?
d. Calculate the critical value of the free length of the spring to avoid buckling.
