Tay Rail Bridge
The Tay Bridge carries rail traffic across the Firth of Tay in Scotland between Dundee and the suburb of Wormit in Fife. Its span is . It is the second bridge to occupy the site. Plans for a bridge over the Tay to replace the train ferry service emerged in 1854, but the first Tay Bridge did not open until 1878. It was a lightweight lattice design of relatively low cost with a Single-track railway, single track. On 28 December 1879, the Tay Bridge disaster, bridge suddenly collapsed in high winds while a train was crossing, killing everybody on board. The incident is one of the worst bridge-related engineering disasters in history. An enquiry determined that the bridge was insufficiently engineered to cope with high winds. It was replaced by a second bridge constructed of iron and steel, with a double-track railway, double track, parallel to the remains of the first bridge. Work commenced on 6 July 1883 and the bridge opened in 1887. The new bridge was subject to extensive testin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dundee Law
Dundee Law is a hill in the centre of Dundee, Scotland, and is the highest point in the city. The Law is what remains of a volcanic sill, which is the result of volcanic activity around 400 million years ago. With a large war memorial at its summit, it is the most prominent feature on the local skyline. Geology Dundee Law, which takes its name from a Scots word for a prominent hill, is an example of a volcanic sill. A volcanic area miles to the west forced lava through fissures in Old Red Sandstone. The subsequent action of rain, wind and ice eroded the sandstone, revealing the volcanic rock. Glaciers during the ice ages deposited more debris around the base, creating a crag and tail. The shallow gradient of the northern and eastern slopes of the law suggest a north-easterly movement of ice flows. The summit of the hill is over above sea level. Despite the derivation of "law" making it tautological to do so, the Law is commonly referred to as the "Law Hill". History Archa ...

Wrought Iron
Wrought iron is an iron alloy with a very low carbon content (less than 0.05%) in contrast to that of cast iron (2.1% to 4.5%), or 0.25 for low carbon "mild" steel. Wrought iron is manufactured by heating and melting high carbon cast iron in an open charcoal or coke hearth or furnace in a process known as puddling. The high temperatures cause the excess carbon to oxidise, the iron being stirred or puddled during the process in order to achieve this. As the carbon content reduces, the melting point of the iron increases, ultimately to a level which is higher than can be achieved by the hearth, hence the wrought iron is never fully molten and many impurities remain. The primary advantage of wrought iron over cast iron is its malleability - where cast iron is too brittle to bend or shape without breaking, wrought iron is highly malleable, and much easier to bend. Wrought iron is a semi-fused mass of iron with fibrous slag inclusions (up to 2% by weight), which give it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Tay Rail Bridge As Seen Across The Tay Estuary From Newport-on-Tay
''The'' is a grammatical article in English, denoting nouns that are already or about to be 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 nouns 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 the archaic pronoun ''thee' ...

Stainmore
Stainmore is a remote geographic area in the Pennines on the border of Cumbria, County Durham and North Yorkshire. The name is used for a civil parish in the Westmorland and Furness of Cumbria, England, including the villages of North Stainmore and South Stainmore. The parish had a population of 253 in the 2001 census, increasing to 264 at the Census 2011. Stainmore Forest stretches further east into County Durham, towards Bowes. Geography Stainmore is drained by the River Belah to the west and, to the east, the River Balder, Deepdale Beck, and the River Greta. It is crossed by the Roman road from Bowes to Brough, now part of the A66, and formerly by the Stainmore Railway. Each of these lines of communication has made use of the relatively low broad saddle between the higher hills to north and south which is commonly referred to as the Stainmore Gap. The summit of the former railway is around above sea level, though the roads climb to slightly higher elevations. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Durham & Lancashire Union Railway
The South Durham and Lancashire Union Railway (SD&LUR) built a railway line linking the Stockton and Darlington Railway near Bishop Auckland with the Lancaster and Carlisle Railway (the West Coast Main Line) at Tebay, via Barnard Castle, Stainmore Summit and Kirkby Stephen. The line opened in 1861 and became known as the Stainmore Line. The Stockton and Darlington absorbed the SD&LUR, and the Stockton and Darlington became a constituent of the North Eastern Railway. The line closed in stages between 1952 and 1962. A short section of the line at Kirkby Stephen East station has been restored by the Stainmore Railway Company. Origins When the Lancaster and Carlisle Railway (L&CR) was approved in June 1844 there were a number of schemes for a railway over the Pennines. The York & Carlisle Railway proposed a route from the East Coast Main Line (ECML) at Northallerton via Richmond, Barnard Castle, the Tees Valley, Stainmore and the Eden Valley to the L&CR at Clifton.

Belah Viaduct
The Belah Viaduct was a railway viaduct on the South Durham and Lancashire Union Railway, crossing the River Belah, in Cumbria, England, about south of the village of Barras, Cumbria, Barras and east north east of Kirkby Stephen. It was completed in 1860 and was demolished in 1963. The viaduct was designed by Thomas Bouch and the ironwork was supplied and erected by Gilkes Wilson; both Bouch and Gilkes Wilson were also responsible for the later Tay Rail Bridge, Tay Bridge. It had Warren truss, 'double' Warren truss girders on cast iron columns, and was constructed at a cost of £31,630. The foundation stone was laid in November 1857. The first locomotive crossed the viaduct in November 1860, and the line opened on 7 August 1861. It was long, wide, with 16 spans, and at it was the highest bridge in England when it was built (but lower than the Crumlin Viaduct in Wales). Post-WWII, weight limitations on the aging viaduct and its limited maintenance led to a ban on do ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thermal Expansion
Thermal expansion is the tendency of matter to increase in length, area, or volume, changing its size and density, in response to an increase in temperature (usually excluding phase transitions). Substances usually contract with decreasing temperature (thermal contraction), with rare exceptions within limited temperature ranges ('' negative thermal expansion''). Temperature is a monotonic function of the average molecular kinetic energy of a substance. As energy in particles increases, they start moving faster and faster, weakening the intermolecular forces between them and therefore expanding the substance. When a substance is heated, molecules begin to vibrate and move more, usually creating more distance between themselves. The relative expansion (also called strain) divided by the change in temperature is called the material's coefficient of linear thermal expansion and generally varies with temperature. Prediction If an equation of state is available, it can be used t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dusk On A Sunny Summers Day Across Dundee, Scotland, July 17, 2007
Dusk occurs at the darkest stage of twilight, or at the very end of astronomical twilight after sunset and just before nightfall.''The Random House College Dictionary'', "dusk". At predusk, during early to intermediate stages of twilight, enough light in the sky under clear conditions may occur to read outdoors without artificial illumination; however, at the end of civil twilight (when Earth rotates to a point at which the center of the Sun's disk is 6° below the local horizon), such lighting is required to read outside. The term ''dusk'' usually refers to astronomical dusk, or the darkest part of twilight before night begins. Technical definitions The time of dusk is the moment at the very end of astronomical twilight, just before the minimum brightness of the night sky sets in, or may be thought of as ''the darkest part of evening twilight''. However, technically, the three stages of dusk are as follows: *At civil dusk, the center of the Sun's disc goes 6° below the ...

Gustave Eiffel
Alexandre Gustave Eiffel ( , ; Bonickhausen dit Eiffel; 15 December 1832 – 27 December 1923) was a French civil engineer. A graduate of École Centrale des Arts et Manufactures, he made his name with various bridges for the French railway network, most famously the Garabit Viaduct. He is best known for the world-famous Eiffel Tower, designed by his company and built for the Exposition Universelle (1889), 1889 Universal Exposition in Paris, and his contribution to building the Statue of Liberty in New York. After his retirement from engineering, Eiffel focused on research into meteorology and aerodynamics, making significant contributions in both fields. Early life Alexandre Gustave Eiffel was born in France, in the Côte-d'Or, the first child of Catherine-Mélanie (née Moneuse) and Alexandre Bonickhausen dit Eiffel. He was a descendant of Marguerite Frédérique (née Lideriz) and Jean-René Bönickhausen, who had emigrated from the Germany, German town of Marmagen and set ...
