Torsion of a circular shaft with diametrically opposite flat sides

Abstract

The research reported here was done at the U.S. Naval Postgraduate School, Monterey, California during the period February through April, 1954. The work was undertaken to determine experimentally the maximvm stress and the torsional rigidity of a round shaft with diametrically opposite parallel flat sides. This information was obtained for several configurations by direct experiment and for one configuration by an electrical analogy.
