Work Step by Step
Springs were selected from Part 3 of Shigley's Mechanical Engineering Design 10th Edition. The Spring Manufacturers Institute (SMI) website was located (www.smihq.org), five manufacturers were searched in the member's directory, and then, the information was reported consulting the Thomas Register of American Manufacturers (www.thomasnet.com).
