Notes on the design of latticed columns subject to lateral loads
A 1922 technical report issued by NASA's Technical Reports Server, a structural engineering note on designing latticed columns under lateral loads, written for engineers and drafters. Its two pictures are a plain black-and-white graph of Euler-pin end load against slenderness ratio, with a curve falling steeply from about 260,000 to near 40,000 pounds per square inch, and a cross-section and elevation drawing of a diagonal lattice bracing between two steel channel members. A designer could take from them the look of dense engineering line drawings, with fine gridlines, dimension callouts and diagonal web patterns.
