The catenary suspension bridge of Real Ferdinando or the Ferdinandeo Bridge over the River Garigliano was the first iron catenary suspension bridge built in Italy, and one of the earliest in continental Europe. This bridge, which was technologically advanced for its age, was built in 1832 by the Bourbon Kingdom of Two Sicilies [1] [2] The engineer who designed the bridge was Luigi Giura.
In physics and geometry, a catenary is the curve that an idealized hanging chain or cable assumes under its own weight when supported only at its ends in a uniform gravitational field.
A suspension bridge is a type of bridge in which the deck is hung below suspension cables on vertical suspenders. The first modern examples of this type of bridge were built in the early 1800s. Simple suspension bridges, which lack vertical suspenders, have a long history in many mountainous parts of the world.
A cable-stayed bridge has one or more towers, from which cables support the bridge deck. A distinctive feature are the cables or stays, which run directly from the tower to the deck, normally forming a fan-like pattern or a series of parallel lines. This is in contrast to the modern suspension bridge, where the cables supporting the deck are suspended vertically from the main cable, anchored at both ends of the bridge and running between the towers. The cable-stayed bridge is optimal for spans longer than cantilever bridges and shorter than suspension bridges. This is the range within which cantilever bridges would rapidly grow heavier, and suspension bridge cabling would be more costly.
An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, electric multiple units, trolleybuses or trams. The generic term used by the International Union of Railways for the technology is overhead line. It is known variously as overhead catenary, overhead contact line (OCL), overhead contact system (OCS), overhead equipment (OHE), overhead line equipment, overhead lines (OHL), overhead wiring (OHW), traction wire, and trolley wire.
The province of Treviso is a province in the Veneto region of Italy. Its capital is the city of Treviso. The province is surrounded by Belluno in the north, Vicenza in the west, Padua in southwest, Venice in the south-east and Friuli-Venezia Giulia in the east. The current President of Treviso is Stefano Marcon, elected in September 2016. He is also the current mayor of Castelfranco Veneto.
A simple suspension bridge is a primitive type of bridge in which the deck of the bridge lies on two parallel load-bearing cables that are anchored at either end. They have no towers or piers. The cables follow a shallow downward catenary arc which moves in response to dynamic loads on the bridge deck.
Minturno is a city and comune in southern Lazio, Italy, situated on the north west bank of the Garigliano.
Sessa Aurunca is a town and comune in the province of Caserta, Campania, southern Italy. It is located on the south west slope of the extinct volcano of Roccamonfina, 40 kilometres (25 mi) by rail west north west of Caserta and 30 kilometres (19 mi) east of Formia.
The New Canaan Branch is an 8.2-mile (13 km) long branch line of the Metro-North Railroad New Haven Line that begins from a junction east of downtown Stamford, Connecticut, north to New Canaan. It opened in 1868 as the New Canaan Railroad.
The Roberto Clemente Bridge, also known as the Sixth Street Bridge, spans the Allegheny River in downtown Pittsburgh, Pennsylvania, United States.
The Waldo–Hancock Bridge was the first long-span suspension bridge erected in Maine, as well as the first permanent bridge across the Penobscot River downstream from Bangor. The name comes from connecting Waldo and Hancock counties. The bridge was built in 1931 and retired in 2006, when the new Penobscot Narrows Bridge was opened just a few yards away, and it was demolished in 2013.
A stressed ribbon bridge is a tension structure similar in many ways to a simple suspension bridge. The suspension cables are embedded in the deck, which follows a catenary arc between supports. As with a simple suspension bridge, the weight is taken by the suspension cables, but unlike the simple span, the deck or ribbon is stressed in compression, which adds to the stiffness of the structure. The supports in turn sustain upward-thrusting arcs that allow the grade to be changed between spans. Such bridges are typically made from concrete reinforced by steel tensioning cables. Where such bridges carry vehicle traffic, a certain degree of stiffness is required to prevent excessive flexure of the structure, obtained by stressing the concrete in compression.
Fall River Township is located in LaSalle County, Illinois. As of the 2010 census, its population was 763 and it contained 339 housing units. Fall River Township was formed from Grand Rapids Township on an unknown date.
A parabolic arch is an arch in the shape of a parabola. In structures, their curve represents an efficient method of load, and so can be found in bridges and in architecture in a variety of forms.
A catenary arch is a type of architectural arch that follows an inverted catenary curve. The catenary curve has been employed in buildings since ancient times. It forms an underlying principle to the overall system of vaults and buttresses in stone vaulted Gothic cathedrals and in Renaissance domes. It is not a parabolic arch.
Novo Selo is a village in the municipality of Surdulica, Serbia. According to the 2002 census the village has a population of 211 people.The etymology of the village comes from Slavic languages meaning new village, Novo Selo.
The New York, New Haven and Hartford Railroad pioneered electrification of main line railroads using high-voltage, alternating current, single-phase overhead catenary. It electrified its mainline between Stamford, Connecticut, and Woodlawn, New York, in 1907 and extended the electrification to New Haven, Connecticut, in 1914. While single-phase AC railroad electrification has become commonplace, the New Haven's system was unprecedented at the time of construction. The significance of this electrification was recognized in 1982 by its designation as a Historic Mechanical Engineering Landmark by the American Society of Mechanical Engineers (ASME).
The Black Suspension Bridge spans the Colorado River in the inner canyon of Grand Canyon National Park. The span length is 440 feet (130 m). The bridge is part of the South Kaibab Trail and is the river crossing used by mules going to Phantom Ranch. The Black Bridge and Silver Bridge, located about 700 metres (2,300 ft) downstream, are the only spans in hundreds of river miles.
Akron is an unincorporated community in Boone County, Nebraska, United States.
A weighted catenary is a catenary curve, but of a special form. A "regular" catenary has the equation
