Analysis of a Strut with a Single Elastic Support in the Span, with Applications to the Design of Airplane Jury-strut Systems
A 1935 NACA technical note on the structural analysis of aircraft jury struts, issued by the National Advisory Committee for Aeronautics for engineers and aircraft designers. The page shows three photographs of a test rig with a vertical strut, elastic support, and a dial gauge, captioned Figures 13 to 15. A designer might take from it the plain, utilitarian look of early laboratory apparatus, with its uniform grey tones, lightly lit metal frames, and typewritten captions set below each photograph.
