A compression spring is needed to fit within a 1-in diameter hole. For clearance, the outside diameter of the spring can be no larger than 0.9 in. To ensure a reasonable coil, use a spring index of 8. The spring is to be used in a machine by compressing it from a free length of 3-in to a solid length of 1-in. The spring is to have squared ends and is to be made of unpeened music wire. a) Determine a suitable wire diameter. b) Determine a suitable total number of coils. c) Determine the spring constant. d) Determine the static factor of safety when the spring is compressed to solid length. e) Determine the fatigue factor of safety when the spring repeatedly cycled from free length to solid length.

A compression spring needed for a machine operation has to fit within a 1-in. diameter hole. To allow for some clearance, the outside diameter of the spring should not be larger than 0.9 in. To ensure a reasonable coil, use a spring index of 9. The spring will be repeatedly cycled from its free length of 3 in. to a length of 2 in. The solid length of the spring is 1 in. The spring should have squared ends and is to be made of music wire. (a) Determine a suitable wire diameter. (b) Determine a suitable number of coils. (c) Determine the spring rate. (d) Calculate the maximum shear stress the spring will experience during fatigue cycling. (e) Show on a stress vs. time plot how the fatigue cycling on the spring will occur. (f) If the spring is unpeened, what will be the shear endurance limit of the spring material in completely reversed cycling? (g) Can the spring survive a million fatigue cycles? Show by calculation.
