Abstract

Using continuum elasticity theory, we describe the elastic behavior of helical coils with an asymmetric double-helix structure and identify conditions, under which they become very rigid. Theoretical insight gained for macro-structures including a stretched telephone cord and an unsupported helical staircase is universal and of interest for the elastic behavior of helical structures on the micro- and nanometer scale.

    • Thought HN folks would enjoy this engineering marvel, a helix staircase built in the 1800s with no nails or central support column, under mysterious circumstances. * A short piece on the engineering: https://nanoten.com/travel/Santa-Fe/ * An academic paper on the underlying…
