A helical compression spring is wound using QQ&T A229 wire. The spring is needed to support a 25-lbf load after being compressed 1.5 in. Because of assembly considerations, the solid height cannot exceed 1.5 in and the free length cannot be more than 3.5 in. Design the spring with both ends squared and ground. You may assume that the static factor of safety ns? 1.2, the fractional overrun to closure? = 0.15, and G = 11.5 Mpsi. The spring maker has the following wire sizes in stock: 0.063, 0.068, 0.072, 0.079, 0.084, 0.087, and 0.090 in. Use the cost of the wire from which the spring is wound as the figure of merit for your selection.
