Lever structures fascinate due to the lightness of their seemingly interwoven elements. The diverse shapes and patterns of the constructions arise from the interplay of mutually supporting rods—a technique that builders have utilized for centuries. The history of this now little-known load-bearing principle is the subject of the first part of the book; it spans from Renaissance builders like Leonardo da Vinci to contemporary architecture. In the second part, the publication provides insight into the internal order of the principle and demonstrates how digital tools can expand the current applications of lever structures.
