Buckling tests of light-metal tubes
This is an official aeronautical technical memorandum from the National Advisory Committee for Aeronautics, published in 1929 as a report on buckling tests of light-metal tubes for aircraft structures. Its three plates are engineering graphs and photographs made for engineers and researchers. Plate one plots tensile force against elongation for four legs, plate two plots stress curves, and plate three shows test rigs with compression set-ups and forms of rupture, giving designers a sober record of industrial test apparatus and graph layouts.
