註釋
A series of tests was made in which the column strength of 17S-T tubing was increased as much as 50 percent by prestressing the tubing to 40,000 pounds per square inch in cmpression under conditions of support that prevented column failure at this stress. This prestressing achieves its beneficial effects entirely by improving the compressive properties of the material, principally the proportional limit.
