Effects of Bending Wire Rope

An ever-present susp1c10n appears in the discussion of wire rope to the effect that the popular formulas for the estimation of the loss of strength due to bending may not be consistent with experiment. This can be settled only by holding the problem up to engineering and analytical scrutiny. This paper is a start along this path. New and more comprehensive formulas are presented, which may serve a useful purpose in bringing to light data and analyses of the problem that have not been published by those who have given their attention to the subject. Wire rope is one of the most used, and most abused, commodities of industry. Therefore, all its properties should be known, to the end that the public and the wire rope manufacturer may agree upon the increase in its cost, if necessary to provide for more safeguards in the selection of materials and in the process of manufacture, so that its performance may be predicted for a properly supervised service.
