1 A steel helical spring carries a compressive load of 32.4 pounds at a deflection of 0.25 inches. Maximum stress is 73240psi. The spring has 1.5 end turns. Calculate the value of c for the spring of minimum volume material. Calculate the value of d and choose the nearest standard wire diameter for the actual spring. Calculate the corresponding R and the number of active coils Nc. Also, calculate the material in the spring.
