Compression struts with nonprogressively variable moment of inertia
This 1938 NASA technical report, issued through the NASA Technical Reports Server, presents engineering design charts for compression struts whose moment of inertia changes in steps rather than gradually, aimed at structural engineers and aircraft designers. Its pictures are plain line graphs of dimensionless curves, with dashed and solid families plotted against length ratios and parameter values, offering a designer a clean, sparse grid-and-curve vocabulary for technical diagrams.
