A theory for primary failure of straight centrally loaded columns
This is a 1938 NASA technical report on the primary failure theory of straight, centrally loaded columns, issued for engineers and aeronautical designers through the NASA Technical Reports Server. Its pictures are dense engineering graphs of nondimensional curves plotted on grid paper, alongside a labelled cross-section diagram and schematic drawings of column buckling modes with dashed and solid outlines, offering a designer a clear model of structural line charts and technical diagram layout.
