    The Secret of the Arch: Practical Designs

    As seen in this post, the theory of the arch can be used to advantage to build stronger bridges. In keeping with the practical side of things, also included in this post is an empirical formula for arch thickness.

    The Secret of the Arch: The Principles

    The arch relies on compression to create a line of thrust that holds the arch stones in place. In this post, we investigate some of the theory of the arch and its line of thrust.
