Test of specimen of wood of longerons of the S.E.5 airplane after seven years' service
A 1922 NASA technical report, issued by the NASA Technical Reports Server, that records a strength test of a wood specimen taken from the longerons of an S.E.5 airplane after seven years of service. Its single picture is a load-deflection graph for designers and engineers studying aircraft material performance. The chart's rising curves, plotted points, and labelled test lines offer a clean, technical diagram for layouts needing measured data styling.
