Ahelical compression spring is to be made of oil-tempered wire, d, of diameter 1–mm with a spring index of c = 10. the spring is to operate inside a hole, so buckling is not a problem and the ends can be left plain. the free length of the spring, lo, should be 86 mm. a force of 50 n should deflect the spring 15 mm.
