A Short Method of Calculating Torsional Stresses in an Airplane Fuselage
A 1924 NACA technical note, issued by the National Advisory Committee for Aeronautics and preserved through NASA's Technical Reports Server, presenting a method for calculating torsional stresses in aircraft fuselages for engineers. The photographs show test rigs and structural frames with cables and load gauges, and the final page carries a line diagram and a plotted torsion curve. A designer might take from them the spare, graph-paper look of early engineering documentation, with its black-and-white photographs and technical line drawings.
