. A helical compression spring is to be made of oil-tempered wire of 4 mm diameter 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 should be 80 mm. A force of 50 N should deflect the spring 15 mm. (Take: G= 77 GPa) 1- Determine the minimum hole diameter for the spring to operate in. 2-Determine the solid length. 3-Determine a static factor of safety based on the yielding of the spring if it is compressed to its solid length.
