An article in the Journal of Structural Engineering describes an experiment to test the yield strength of circular tubes with caps welded to the ends. The first yield (in kN) are 96, 97, 102, 106, 105, 104, 112, 108, 126, 126, 127,128, 140, 156, 160, 163, 164, and 175.Output from a software package follows:
