What Is the Shape of a Cupola? López Camino, Rafael This article examines the shape of a surface obtained by a hanging flexible, inelastic material with prescribed area and boundary curve. The shape of this surface, after being turned upside down, is a model for cupolas (or domes) under the simple hypothesis of compression. Investigating the rotational examples, we provide and illustrate a novel design for a roof which has the extraordinary property that its shape, although natural, is modeled by a surface of revolution whose axis of rotation is horizontal. 2024-01-23T08:21:34Z 2024-01-23T08:21:34Z 2021-11-05 journal article Published version: https://doi.org/10.1080/00029890.2022.2154557 https://hdl.handle.net/10481/87122 10.1080/00029890.2022.2154557 eng http://creativecommons.org/licenses/by-nc-nd/3.0/ open access Creative Commons Attribution-NonCommercial-NoDerivs 3.0 License Taylor& Francis Online
