Meramec bridge

Abstract

"Bridge-building, as a science, is comparatively of recent date, for relating to now, of what may be called ancient bridges, do we read of them having been mathematical calculations, determining the strains upon the constituent parts of the bridge structure. This very necessary operation seems to have been entirely omitted. This was, probably, because to that time, there had been no thoroughly scientific investigation, of the new and beautiful subject of scientific bridge-building. At the present time, we determine with a minuteness the strain thrown upon any part of a bridge. We are thus enabled to give the proper dimensions to every component part of a bridge, a desideratum, since any superfluous strength, may by the weight due to it, tend to weaken the entire structure. This is particularly so, when the superfluous strength is represented by wooden timbers. In wrought iron, more strength must be given than is actually required, since a strain that will not break, will lengthen the parts, especially, when they are subjected to strains for any considerable length of time. This is the reason that those parts bearing tensile strains, when represented by wrought iron, are much longer, than it would seem to require. In the bridge under consideration, this is a very noticeable feature"--pages 4-5.
