Problems Involved in the Choice and Use of Materials in Airplane Construction
This is a 1932 technical report on aircraft materials, issued by the NASA Technical Reports Server and compiled for engineers choosing and using materials in airplane construction. The four pictures are engineering graphs: a loss-of-strength curve, a dynamic stress diagram with a shaded safe region, buckling stress against slenderness ratio, and tensile strength against grain angle for plywood. A designer could take their clean black linework, dashed and dotted curve styles, and grid layouts as a model for technical charts.
