Analysis of wing truss stresses including the effect of redundancies
This is a 1921 technical report from the NASA Technical Reports Server archive, a government aeronautical engineering study analysing stresses in aircraft wing trusses and the effect of redundant members. It was written for aircraft designers and structural engineers. The four pictures are line drawings: plan and side views of a biplane, and a wing truss diagram with numbered members and loads. A designer could take from them the clean, precise drafting style of early aviation schematics and the geometric lattice of braced structures.
