3. Arches and Chains

Lecture 3, Arches and Chains, from the Engineering Models series. It explains how a hanging chain traces the ideal shape of an arch and how that principle, used in Gaudi's hanging chain models, is turned into structural form.

HN people recommend it as a good overview of the hanging chain technique, and link it whenever Gaudi's Sagrada Familia comes up.
