A method of calculating the ultimate strength of continuous beams
A 1931 NASA technical report, issued through the NASA Technical Reports Server, presenting a method for calculating the ultimate strength of continuous beams for engineers. The single picture is a mechanical line drawing of a loading apparatus for testing beams, with vertical uprights, a movable head testing machine, and a long wing beam with horizontal arms. A designer might take its precise, labelled engineering diagram style, with thin black linework on a white field, as a model for technical schematics.
