Both it and the arch are built of Istrian stone.

At the entrance to the latter the senate erected, in his honour, a triumphal arch which is still extant - a fine simple monument with a single opening.

Generally the line of pressure lies within the middle half of the depth of the arch ring.

For an elastic arch of metal there is a more complete theory, but it is difficult of application, and there remains some uncertainty unless (as is now commonly done) hinges are introduced at the crown and springings.

So far as superstructure is concerned, more material must be used than for an arch or chain, for the girder is in a sense a combination of arch and chain.

On the other hand, a girder imposes only a vertical load on its piers and abutments, and not a horizontal thrust, as in the case of an arch or suspension chain.

A granite arch built in 1377 over the Adda at Trezzo had a span at low water of 251 ft.

The centre arch has a span of 152 ft., and rises 29 ft.

The voussoirs of the centre arch (all of granite) are 4 ft.

The bridge is not continuous in width, there are arch rings on each face, each 16.4 ft.

One centering was used for the two arch rings, supported on dwarf walls which formed a slipway, along which it was moved after the first arch was built.

The stability of such structures depends on the position of the line of pressure relatively to the intrados and extrados of the arch ring.

But if hinges are introduced at crown and springings, the calculation of the stresses in the arch ring becomes simple, as the line of pressures must pass through the hinges.

The arch is 15 in.

After various repairs and strengthenings, including the replacement of the timber girder by an iron one in 1880, this bridge in 1896-1897 was taken down and a steel arch built _ _ __ _ I ?

By curving the top boom of a girder to form an arch and the bottom boom to form a suspension chain, the need of web except for non-uniform loading is obviated.

Baker stated that it had required patching for ninety years, because the arch and the high side arches would not work together.

Expansion and contraction broke the high arch and the connexions between the arches.

The difficulty of casting heavy arch ribs led to the construction of cast iron arches of cast voussoirs, somewhat like the voussoirs of masonry chambers and air locks, a feat unprecedented in the annals of engineering.

The rise of the centre arch is 471 ft., and that of the side arches 46 ft.

The arch rests on rollers and is narrowest at the crown.

The Victoria Falls bridge over the Zambezi, designed by Sir Douglas Fox, and completed in 1905, is a combination of girder and arch having a total length of 650 ft.

Each half arch was supported by cables till joined at the centre.

The deepest part of the valley is crossed by an arch of 541 ft.

It is formed by a crescent-shaped arch, continued on one side by four, on the other side by two lattice girder spans, on iron piers.

The arch is formed by two lattice ribs hinged at the abutments.

The two arch ribs are 652 ft.

The lattice girders of the side spans were first rolled into place, so as to project some distance beyond the piers, and then the arch ribs were built out, being partly supported by wire-rope cables from (3) Draw or Bascule Bridges.

Since the erection of the Forth bridge, cantilever bridges have been extensively used, and some remarkable steel arch and suspension bridges have also been constructed.

The intermediate piers should also have considerable stability, so as to counterbalance the thrust arising when one arch is loaded while the other is free from load.

The girders of the side spans were rolled out so as to overhang the great span by 105 ft., and formed a platform from which parts of the arch could be suspended.

A frame used to support a weight is often called a truss; the stresses on the various members of a truss can be computed for any given load with greater accuracy than the intensity of stress on the various parts of a continuous structure such as a tubular girder, or the rib of an arch.

Produced by long-continued subaerial decay and erosion, in later Cretaceous times this lowland extended from the Atlantic Ocean well toward the interior of North America; since then the whole continent has been generally elevated, and by successive steps the Appalachian belt has been raised to form a wide but relatively low arch.

The master streams of the present have inherited their channels from the drainage systems of the Cretaceous lowland, and though raised athwart the courses of the lowland trunk streams the great arch was developed so slowly that these channels could be maintained through pari passu deepening.

The river is here crossed by three bridges; the (upper) steel arch bridge, built (1895) on the site of the former suspension bridge (built in 1869; blown down in 1889; rebuilt as a suspension bridge) near the Falls, is crossed by double carriageways and footpaths and by an electric railway, and is probably the longest bridge of the kind in the world, being 1240 ft.

A stone arch bridge, with nine arches, built of granite at a cost of $1,700,000 and dedicated in 1908, spans the Connecticut (replacing the old Connecticut river bridge built in 1818 and burned in 1895), and connects Hartford with the village of East Hartford in the township of East Hartford (pop. 1900, 6406), which has important paper-manufacturing and tobacco-growing interests.

Near the Capitol, at the approach of the memorial bridge across the Park river, is the Soldiers' and Sailors' memorial arch, designed by George Keller and erected by the city in 1885 in memory of the Hartford soldiers and sailors who served in the American Civil War.

Amongst the Arabs, lands were either held in common by a whole tribe, under a tenure known as the arch or sabegha, or sometimes, especially in the towns, under a modified form of freehold (melk) by the family.

Both as regards structure and habits, the leopard may be reckoned as one of the more typical representatives of the genus Felis, belonging to that section in which the hyoid bone is loosely connected with the skull, owing to imperfect ossification of its anterior arch, and the pupil of the eye when contracted under the influence of light is circular, not linear as in the smaller cats.

Caelus is sometimes associated with Terra, represented in plastic art as an old, bearded man holding a robe stretched out over his head in the form of an arch.

A broad, low crustal arch extends southward at the junction of the Atlantic and Gulf coastal plains; the emerged half of the arch, constitutes the visible lowland peninsula of Florida; the submerged half extends westward under the shallow Florida.

Flanking strata are even better exhibited in the Bighorn Mountains, the front range of northern Wyoming, crescentic in outline and convex to the northeast, like the Laramie Range, but much higher; here heavy sheets of limestone arch far up towards the range crest, and are deeply notched where consequent streams have cut down their gorges.

Below the town to the north is a single arched bridge of the road, the arch having the span of 381 ft.

The socalled Arco di Riccardo is a half-buried Roman arch with Corinthian pilasters, possibly a triumphal arch, possibly connected with an aqueduct.

A triumphal arch at Vesontio (Besancon), which in return for this service was made a colony, possibly commemorates this victory.

Of the Dominican monastery (1224) there still exists the stately Magdalen tower; while of the Augustinian abbey of St Mary d'Urso (1206) there are the tower and a fine pointed arch.

The zygomatic arch is variously developed, and the position of the jugal is a character for grouping the families.

The front root of the zygomatic arch is nearly vertical, and placed so far back that it is above the second molar, while the orbit - a unique feature among rodents - is almost completely surrounded by bone.

In the skull the zygomatic arch is slender and the jugal bone small and not extending far forwards, being supported by the long zygomatic process of the maxilla, while the infra-orbital foramen is mostly large, and there are no post-orbital processes.
