Computation of cantilever airplane wings
A 1925 NASA technical report on computing stresses in cantilever airplane wings, presented as a set of engineering diagrams for analysts working on wing structures. Its pictures are line drawings of a wing modelled as a grid of panels fixed at one root edge, with arrows for loads and shaded areas for bending-moment diagrams, offering a designer clear schematic motifs of hatched supports, dashed panel lines and stepped load arrows.
