Tests on built-up airplane struts having initial tension in outside fibers

T. A. Schwamb, C. S. Smith
August, 1923

The conventional airplane strut fails by buckling. The first signs of failure usually are compression cracks on the concave side of bending. It would therefore appear that if an initial tension could be introduced in the outside fibers, this tension would have to be relieved before the compression load could make itself felt.
