Formulas for the Stress Analysis of Circular Rings in a Monocoque Fuselage
This is a 1933 NACA-era engineering report, issued by NASA's technical reports archive, giving stress formulas for circular ring frames in aircraft monocoque fuselages. Its pictures are line diagrams of ring cross-sections with angular dimensions, arrowed load vectors in pounds, and labelled points, which a designer might borrow as clean technical schematic style for mechanical or structural graphics.
