The Discovery of General Methods for the Calculation of Elastic Systems more generally, including any sort of structure used in civil engineering. If we replace “elastic system” with “frame,” the applications become obvious—and we can make this substitution. Or we can define “frame” in a more abstract way; as J. Clerk Maxwell put it, “a frame is a system of lines connecting a number of points.”.

Alphabet der Schriftstellerinnen, can call the first one “the problem of the egg”: how can an apparently fragile curve support heavy loads? What curve is the strongest? What is the best curve for a given practical application? The second, we can call “the problem of the wall”: what are the best dimensions for a pair of abutments?

The old models were graceful, harmonic, based on proportions which combined beauty and strength. Everyone firmly believed that the arch was the most stable of architectural figures; what needed refinement were the technical methods—sc
