Torsional stresses in box beams with cross sections partially restrained against warping
This is a 1934 NASA technical report, issued through the NASA Technical Reports Server, on the torsional stresses in box beams whose cross sections are partly restrained against warping; it is written for aircraft structural engineers. The pictures are engineering line drawings of rectangular box beams with bulkheads, showing shear and stress distributions as shaded diagrams, wedge-shaped cell sections, and graphs of redundancy values plotted against bulkhead spacing. A designer might take from them the clean isometric drawing style, the dense black-and-white stress-flow shading, and the stepped graph layouts.
