Compressive Strength of Tapered Airplane Struts
A 1923 NASA technical report on the compressive strength of tapered airplane struts, presented as an engineering paper for aeronautical engineers and designers of early aircraft structures. The single picture is a numbered graph of curves plotting a ratio against a dimensionless variable, with dense families of labelled lines fanning from the upper left toward the lower right and axis ticks from 0 to 1.0 and 0 to 0.5. A designer might take from it the look of technical plotting: fine black hairline curves, small curve labels, and a clean axis grid with a single figure caption.
