Influence of elliptical distribution of lift on strength of airplane wings
A 1922 NASA technical report on how the elliptical spread of lift along an airplane wing affects its structural strength, drawn from the NASA Technical Reports Server collection. The single figure is a line diagram of a wing planform with the spanwise axis running horizontally from the root at O to the tip, marking the lift ordinate y, the elliptical outline, and a small strip dx at station A for calculation; a designer might borrow its clean technical labelling and the tapering elliptical silhouette as a plain engineering motif.
