Garabit Viaduct
The Garabit viaduct (french: viaduc de Garabit) is a railway arch bridge spanning the Truyère, near Ruynes-en-Margeride, Cantal, France, in the mountainous Massif Central region. The bridge was constructed between 1882 and 1884 by Gustave Eiffel, with structural engineering by Maurice Koechlin, and was opened in 1885. It is in length and has a principal arch of span. Background By the late 1870s, Eiffel & Cie, the company founded by Eiffel in partnership with Théophile Seyrig, had established a place among the leading French engineering companies. Between 1875 and 1877, the company had built the Maria Pia Bridge over the Douro at Porto, and when the construction of a railway between Marvejols and Neussargues, both in Cantal, was proposed, the work of constructing a viaduct to cross the Truyère was given to Eiffel without the usual process of competitive tendering. That was at the recommendation of the state engineers since the technical problems involved were similar to t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles ( rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer faci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Cassandra Crossing
''The Cassandra Crossing'' is a 1976 disaster thriller film directed by George Pan Cosmatos and starring Sophia Loren, Richard Harris, Ava Gardner, Martin Sheen, Burt Lancaster, Lee Strasberg and O. J. Simpson about a disease-infected Swedish terrorist who infects a train's passengers as they head to a derelict arch bridge. With the backing of the media tycoon Sir Lew Grade (the head of the British broadcast network Associated Television) and the Italian film producer Carlo Ponti, the international all-star cast was expected to attract a widespread audience, with rights sold prior to filming, to both British and American distributors. Ponti also saw the production as a showcase for his wife, Sophia Loren. Plot When the existence of a strain of plague (vaguely identified as pneumonic) is revealed at the US mission at the International Health Organization, three terrorists seek to blow up the US mission. Two of them are shot, one mortally, by security personnel, but one es ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parabolic Arch
A parabolic arch is an arch in the shape of a parabola.Article about parabolic arch by The Free DictionaryParabolic arch , Article about parabolic arch by The Free Dictionary accessdate: March 2, 2017 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. Description The mathematics While a parabolic arch may resemble a catenary arch, a parabola is a quadratic function while a catenary is the hyperbolic cosine, , a sum of two exponential functions. One parabola is , and hyperbolic cosine is . The curves are unrelated. The line of thrust Unlike a catenary arch, the parabolic arch employs the principle that when weight is uniformly applied above, the internal compression (see line of thrust) resulting from that weight will follow a parabolic curve. Of all arch types, the parabolic arch produces the most thrust at the base. Also, it can span the widest area. It is commonly used in bridge design, ...

Béziers
Béziers (; oc, Besièrs) is a subprefecture of the Hérault department in the Occitanie region of Southern France. Every August Béziers hosts the famous ''Feria de Béziers'', which is centred on bullfighting. A million visitors are attracted to the five-day event. The town is located on a small bluff above the river Orb, about from the Mediterranean coast and southwest of Montpellier. At Béziers, the Canal du Midi passes over the river Orb by means of the '' Pont-canal de l'Orb'', an aqueduct claimed to be the first of its kind. History Béziers is one of the oldest cities in France. Research published in March 2013 shows that Béziers dates from 575 BC, making it older than Agde (Greek Agathe Tyche, founded in 525 BC) and a bit younger than Marseille (Greek Massalia, founded in 600 BC). The site has been occupied since Neolithic times, before the influx of Celts. Roman ''Betarra'' was on the road that linked Provence with Iberia. The Romans refoun ...

Corail (train)
Corail is the name given to a class of passenger rail cars of the SNCF that first entered commercial service in 1975. When introduced, the Corail carriages had improved passenger comfort, featured air-conditioning, and better levels of suspension and sound-proofing compared with previous InterCity carriages. History and design The acquisition of the Corail coaches was a huge investment for SNCF with nearly 4000 carriages ordered, and represented a major leap in quality of service for French rail passengers. The name Corail, which is also used as a designation of service for trains made up of these carriages, derives from combination of 'comfort' and 'rail'. Additionally, 'corail' means 'coral' in French, giving a play-on-words and making it memorable. The carriages were designed by the French industrial designer Roger Tallon and built by the Société Franco-Belge in Raismes, northern France, and by Alstom's La Rochelle factory in Aytré. When introduced, Corail carriage ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Franc
The franc is any of various units of currency. One franc is typically divided into 100 centimes. The name is said to derive from the Latin inscription ''francorum rex'' (King of the Franks) used on early French coins and until the 18th century, or from the French ''franc'', meaning "frank" (and "free" in certain contexts, such as ''coup franc'', "free kick"). The countries that use francs today include Switzerland, Liechtenstein, and most of Francophone Africa. The Swiss franc is a major world currency today due to the prominence of Swiss financial institutions. Before the introduction of the euro in 1999, francs were also used in France, Belgium and Luxembourg, while Andorra and Monaco accepted the French franc as legal tender (Monégasque franc). The franc was also used within the French Empire's colonies, including Algeria and Cambodia. The franc is sometimes Italianised or Hispanicised as the ''franco'', for instance in Luccan franco. Origins The franc was originally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deflection (engineering)
In structural engineering, deflection is the degree to which a part of a structural element is displaced under a load (because it deforms). It may refer to an angle or a distance. The deflection distance of a member under a load can be calculated by integrating the function that mathematically describes the slope of the deflected shape of the member under that load. Standard formulas exist for the deflection of common beam configurations and load cases at discrete locations. Otherwise methods such as virtual work, direct integration, Castigliano's method, Macaulay's method or the direct stiffness method are used. The deflection of beam elements is usually calculated on the basis of the Euler–Bernoulli beam equation while that of a plate or shell element is calculated using plate or shell theory. An example of the use of deflection in this context is in building construction. Architects and engineers select materials for various applications. [Baidu] |
The Garabit Viaduct, 2007, Cantal, Auvergne, France-1
''The'' () is a grammatical article in English, denoting persons or things already mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with pronouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of pronoun ''thee'') when followed by a ...
