A course on the stresses in bridge and roof trusses, arched ribs and suspension bridges
A structural engineering textbook by William H. Burr, published by Wiley in New York in 1904 for students and practising bridge and roof designers. The plates are line diagrams: truss outlines with lettered joints, force polygons, stress and reciprocal diagrams, and dimension arrows, offering designers clean geometric linework, labelled skeletal frameworks, and technical annotation as pattern or ornament.
