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.
An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, trolleybuses or trams. It is known variously as:
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 the southern Lazio, Italy, situated on the north west bank of the Garigliano, with a suburb on the opposite bank about 18 kilometres (11 mi) from its mouth, at the point where the Via Appia crossed it by the bridge called Pons Tiretius.

Biga is a town and district of Çanakkale Province in the Marmara region of Turkey. It is located on the Biga River, 90 kilometres northeast from Çanakkale city centre. According to the 2000 census, population of the district is 80,982 of which 37,196 live in the town of Biga. The district covers an area of 1,354 km2 (523 sq mi), and the town lies at an elevation of 21 m (69 ft).
A stressed ribbon bridge is a tension structure. The suspension cables are embedded in the deck which follows a catenary arc between supports. Unlike the simple span, the ribbon is stressed in traction, which adds to the stiffness of the structure. The supports in turn support 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.

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 National Historic Engineering Landmark by the American Society of Mechanical Engineers (ASME).

A weighted catenary is a catenary curve, but of a special form. A "regular" catenary has the equation
A suspended structure is a structure which is supported by cables coming from beams or trusses which sit atop a concrete center column or core. The design allows the walls, roof and cantilevered floors to be supported entirely by cables and a center column.
