Compression springs are the most common spring configuration that product manufacturer's turn to when enhanced product functionality is required. You are required to design a compression spring that is made of oil-tempered wire of 4-mm diameter with a spring index of C=10. The spring will operate inside a pipe, so buckling is not a problem and select the ends to be plain. The free length of the spring should be 80 mm. A force of 50 N should deflect the spring 15 mm. a) Calculate the spring rate and the solid length. b) Calculate the total number of coils needed. c) Calculate the minimum pipe diameter for the spring to operate in. d) Calculate a static factor of safety based on the yielding of the spring if it is compressed to its solid length.
