Strength Tests on Paper Cylinder in Compression, Bending and Shear
A 1931 NACA technical note from the National Advisory Committee for Aeronautics, issued as a government engineering report on strength tests of paper cylinders under compression, bending and shear, written for aeronautical engineers. Its photographs show rows of plain cylindrical paper models of graduated sizes, labelled with letters, after bending, shear and torsion loading, with one page showing the test rig. A designer could take from them the stark cylinder silhouettes, the crumpled and buckled paper textures, and the orderly numbered plate layouts typical of mid-century technical documentation.
