...this theory consists in making the height of the wall incumbent on any point of the intrados, directly as the cube of the secant of the curve's inclination to the horizon at that point, or inversely as the radius of curvature there. It must be added, that this theory expects... | |

...method of finding the extrados of an arch from a given intrados. From what has been observed at page 25, it may be inferred, that the strength of one part...also in the same proportion ; but, since if one part of an arch fails, the whole will fall to ruin, and as the crown is the weakest part in all arches,... | |

... the practical architect to adopt his visions, raised another system, which is said to secure a perfectly equilibrated structure, by making an equality at every point of the curve. The deduction from this theory consists in making the height of the...
