Effect of stressed covering on strength of internal girders of a wing
A 1929 NASA technical report, issued through the NASA Technical Reports Server, on how a stressed skin covering affects the strength of internal girders in an aircraft wing, written for aeronautical engineers. Its pictures are engineering graphs and plots: stress-versus-position curves with measured and calculated points, ratio curves for buckling load against span, and a labelled stress-distribution diagram. A designer might take the clean line-chart vocabulary, with dashed and solid curves, circle and cross markers, and simple axis labels, as a model for technical infographics.
