Coil springs are used in numerous practical applications. Detailed methods for analyzing and designing such mechanical components have been developed over the years (e.g., Spotts, 1953; Wahl, 1963; Shigley, Mischke, and Budynas, 2004; Haug and Arora, 1979).The purpose of this project is to design a minimum-mass spring (shown in Figure 2.8) to carry a given axial load …
