The Effect of Longitudinal Moment of Inertia upon Dynamic Stability
A 1922 technical report from the NASA Technical Reports Server on how longitudinal moment of inertia affects dynamic stability, likely aimed at aeronautical engineers. The single picture is a photographic record of an oscillation trace, a wavy white curve on a dark ground with a vertical graticule of fine ruling and a handwritten label, which a designer could use as a texture of measurement or instrument readout.
