The Behavior of Thin-will Monocoque Cylinders Under Torsional Vibration
A 1937 NACA technical report issued by the National Advisory Committee for Aeronautics, written for aircraft engineers and researchers studying vibration in thin-walled monocoque cylinders. Its pages are plain engineering graphs of amplitude against forced frequency, with figure captions and one schematic test-rig drawing, so the material suits a designer wanting technical chart styling.
