...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,... | |
