  • Interesting fact: The pineapple was symbol of welcome in the 1700-1800's. That is why in New England you will see so many pineapples on door knockers. An arch in Providence RI leading into the Federal Hill neighborhood has a pineapple on it for that very reason. Pineapples were brought home by seafarers as gifts.
    • n arch In geometry, any part of the circumference of a circle or other curve; an arc. See arc
    • n arch In architecture, a structure built of separate and inelastic blocks, assembled on a curved line in such a way as to retain their position when the structure is supported extraneously only at its two extremities. The separate blocks which compose the arch are called voussoirs or arch-stones. The extreme or lowest voussoirs are termed springers, and the uppermost or central one, when a single stone occupies this position, is called the keystone. The under or concave face of the assembled voussoirs is called the intrados, and the upper or convex face the extrados, of the arch. When the curves of the intrados and extrados are concentric or parallel, the arch is said to be extradosed. The supports which afford resting and resisting points to the arch are piers or pillars, which receive the vertical pressure of the arch, and abutments, which resist its lateral thrust, and which are properly portions of the wall or other structure above the springing and abreast of the shoulder of the arch. The upper part of the pier upon which the arch rests (technically, the point from which it springs) is the impost. The span of an arch is the distance between its opposite imposts. The rise of an arch is the height of the highest point of its intrados above the line of the imposts; this point is sometimes called the under side of the crown, the highest point of the extrados being the crown. The thrust of an arch is the pressure which it exerts outward. This pressure is practically collected, so far as it is manifested as an active force, at a point which cannot be exactly determined theoretically, but is at about one third of the height of the rise of the arch. The thrust must be counteracted by abutments or buttresses. Arches are designated in two ways: First, in a general manner, according to their properties, their uses, their position in a building, or their exclusive employment in a particular style of architecture. Thus, there are arches of equilibration, equipollent arches, arches of discharge, skew and reversed arches, Roman, Pointed, and Saracenic arches. Second, they are named specifically, according to the curve the intrados assumes, when that curve is the section of any of the geometrical solids, as segmental, semicircular, cycloidal, elliptical, parabolical, hyperbolical, or catenarian arches; or from the resemblance of the whole contour of the curve to some familiar object, as lancet arch and horseshoe arch; or from the method used in describing the curve, as equilateral, three-centered, four-centered, ogee, etc. When an arch has one of its imposts higher than the other, it is said to be rampant. Foil arches are arches whose intrados outlines form a series of subordinate arcs called foils, the points of which are termed cusps. A numeral is usually employed to designate the number of foils, as a trefoil arch, a cinquefoil arch, etc.
