Riveting in metal airplane construction. Part II : riveting methods and equipment (concluded)
A 1930 NACA technical memorandum on riveting in metal airplane construction, part II, issued by the United States National Advisory Committee for Aeronautics for aircraft engineers and manufacturers. Its pictures are engineering charts of rivet strength against plate thickness and rivet diameter, plus photographs of a telescope for inspecting rivet heads inside tubular spars and an annealing plant. A designer might take from them the plain line-graph style and the close-up documentary photography of mechanical fastening.
