Tay Bridge Disaster
The Tay Bridge disaster occurred during a violent storm on Sunday 28 December 1879, when the first Tay Rail Bridge collapsed as a North British Railway (NBR) passenger train on the Edinburgh to Aberdeen Line from Burntisland bound for its final destination of Dundee passed over it, killing all aboard. The bridge—designed by Sir Thomas Bouch—used lattice girders supported by iron piers, with cast iron columns and wrought iron cross-bracing. The piers were narrower and their cross-bracing was less extensive and robust than on previous similar designs by Bouch. Bouch had sought expert advice on wind loading when designing a proposed rail bridge over the Firth of Forth; as a result of that advice he had made no explicit allowance for wind loading in the design of the Tay Bridge. There were other flaws in detailed design, in maintenance, and in quality control of castings, all of which were, at least in part, Bouch's responsibility. Bouch died less than a year after the disa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tay Rail Bridge
The Tay Bridge ( gd, Drochaid-rèile na Tatha) carries the railway 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. On 28 December 1879, the bridge suddenly collapsed in high winds. The incident is one of the greatest bridge-related engineering disasters to have occurred. 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, 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 testing by the Board of Trade, which resulted in a favourable report. In 2003, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deck Truss
A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units. The connected elements (typically straight) may be stressed from tension, compression, or sometimes both in response to dynamic loads. The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by 19th and early 20th-century engineers. A truss bridge is economical to construct because it uses materials efficiently. Design The nature of a truss allows the analysis of its structure using a few assumptions and the application of Newton's laws of motion according to the branch of physics known as statics. For purposes of analysis, trusses are assumed to be pin jointed where the straight components meet, meaning that taken alone, every joint on the structure is functionally considered to be a flexible joint as opposed to a rigid joint with strength to maintain its own shape, and t ...

Share (finance)
In financial markets, a share is a unit of equity ownership in the capital stock of a corporation, and can refer to units of mutual funds, limited partnerships, and real estate investment trusts. Share capital refers to all of the shares of an enterprise. The owner of shares in a company is a shareholder (or stockholder) of the corporation. A share is an indivisible unit of capital, expressing the ownership relationship between the company and the shareholder. The denominated value of a share is its face value, and the total of the face value of issued shares represent the capital of a company, which may not reflect the market value of those shares. The income received from the ownership of shares is a dividend. There are different types of shares such as equity shares, preference shares, deferred shares, redeemable shares, bonus shares, right shares, and employee stock option plan shares. Valuation Shares are valued according to the various principles in different market ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stockton And Darlington
The Stockton and Darlington Railway (S&DR) was a railway company that operated in north-east England from 1825 to 1863. The world's first public railway to use steam locomotives, its first line connected coal mining, collieries near Shildon with Darlington and Stockton-on-Tees in County Durham, and was officially opened on 27 September 1825. The movement of coal to ships rapidly became a lucrative business, and the line was soon extended to a new port at Middlesbrough. While coal waggons were hauled by steam locomotives from the start, passengers were carried in coaches drawn by horses until carriages hauled by steam locomotives were introduced in 1833. The S&DR was involved in the building of the East Coast Main Line between York and Darlington, but its main expansion was at Middlesbrough Docks and west into Weardale and east to Redcar. It suffered severe financial difficulties at the end of the 1840s and was nearly taken over by the York, Newcastle and Berwick Railway, be ...

Liquidation
Liquidation is the process in accounting by which a company is brought to an end in Canada, United Kingdom, United States, Ireland, Australia, New Zealand, Italy, and many other countries. The assets and property of the company are redistributed. Liquidation is also sometimes referred to as winding-up or dissolution, although dissolution technically refers to the last stage of liquidation. The process of liquidation also arises when customs, an authority or agency in a country responsible for collecting and safeguarding customs duties, determines the final computation or ascertainment of the duties or drawback accruing on an entry. Liquidation may either be compulsory (sometimes referred to as a ''creditors' liquidation'' or ''receivership'' following bankruptcy, which may result in the court creating a "liquidation trust") or voluntary (sometimes referred to as a ''shareholders' liquidation'', although some voluntary liquidations are controlled by the creditors).

Wormit
Wormit is a village on the south shore of the Firth of Tay in north-east Fife, Scotland. Its location at the southern end of the Tay Rail Bridge has led to it becoming a commuter suburb of Dundee. Together with Woodhaven and Newport-on-Tay, Wormit is a part of The Burgh of Newport-on-Tay. The name of the village is thought to be derived from the plant wormwood. Wormit Station Wormit Railway Station, opened on 1 May 1889 and closed on 5 May 1969, was operated on a closed branch line, The Newport Railway, which left the main line (Edinburgh/Dundee) railway immediately at the south end of the Bridge to serve Wormit/Newport. After closure, Wormit Station was later dismantled and rebuilt at the heritage Bo'ness & Kinneil Railway to the west of Edinburgh. In 1955, there was a serious train crash in Wormit Station in which three people were killed and forty-one were injured. Power Wormit claims to be the first Scottish village to have installed electricity. A windmill located o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Foundry
A foundry is a factory that produces metal castings. Metals are cast into shapes by melting them into a liquid, pouring the metal into a mold, and removing the mold material after the metal has solidified as it cools. The most common metals processed are aluminum and cast iron. However, other metals, such as bronze, brass, steel, magnesium, and zinc, are also used to produce castings in foundries. In this process, parts of desired shapes and sizes can be formed. Foundries are one of the largest contributors to the manufacturing recycling movement, melting and recasting millions of tons of scrap metal every year to create new durable goods. Moreover, many foundries use sand in their molding process. These foundries often use, recondition, and reuse sand, which is another form of recycling. Process In metalworking, casting involves pouring liquid metal into a mold, which contains a hollow cavity of the desired shape, and then allowing it to cool and solidify. The sol ...

Teesside
Teesside () is a built-up area around the River Tees in the north of England, split between County Durham and North Yorkshire. The name was initially used as a county borough in the North Riding of Yorkshire. Historically a hub for heavy manufacturing, the number of people employed in this type of work declined from the 1960s onwards, with steel-making and chemical manufacturing (particularly through Imperial Chemical Industries) replaced to some extent by new science businesses and service sector roles. History 1968–1974: County borough Before the county of Cleveland was created, the area (including Stockton-on-Tees) existed as a part of the North Riding of Yorkshire, due to most land being south of the Tees. Teesside was created due to Stockton-on-Tees being linked heavily with Thornaby (which had amalgamated with South Stockton/Mandale to form the Borough of Thornaby), Middlesbrough and Redcar by industry. Compared to the modern Teesside conurbation, the area was sma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Viaduct
A viaduct is a specific type of bridge that consists of a series of arches, piers or columns supporting a long elevated railway or road. Typically a viaduct connects two points of roughly equal elevation, allowing direct overpass across a wide valley, road, river, or other low-lying terrain features and obstacles. The term ''viaduct'' is derived from the Latin ''via'' meaning "road", and ''ducere'' meaning "to lead". It is a 19th-century derivation from an analogy with ancient Roman aqueducts. Like the Roman aqueducts, many early viaducts comprised a series of arches of roughly equal length. Over land The longest in antiquity may have been the Pont Serme which crossed wide marshes in southern France. At its longest point, it measured 2,679 meters with a width of 22 meters. Viaducts are commonly used in many cities that are railroad hubs, such as Chicago, Birmingham, London and Manchester. These viaducts cross the large railroad yards that are needed for freight trains there, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Middlesbrough
Middlesbrough ( ) is a town on the southern bank of the River Tees in North Yorkshire, England. It is near the North York Moors national park. It is the namesake and main town of its local borough council area. Until the early 1800s, the area was rural farming land. By 1830, a new industrial town and port started to be developed, driven by the coal and later ironworks. Steel production and ship building began in the late 1800s, remaining associated with the town until post-industrial decline occurred in the late twentieth century. Trade (notably through ports) and digital enterprise sectors contemporarily contribute to the local economy, Teesside University and Middlesbrough College to local education. In 1853, it became a town. The motto ("We shall be" in Latin) was adopted, it reflects ("We have been") of the Bruce clan which were Cleveland's mediaeval lords. The town's coat of arms is three ships representing shipbuilding and maritime trade and an azure (blue) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gilkes Wilson And Company
Gilkes Wilson and Company was a British locomotive manufacturer at Teesside Engine Works in Middlesbrough which opened in 1843. Initially repairing locomotives, the company built its first engines in 1847. History Gilkes and Wilson was formed as a partnership between Quakers Isaac Wilson and Edgar Gilkes. In 1865 the company merged with Hopkins and Company (establishers of the Tees Side Iron Works, 1857) to become Hopkins Gilkes and Company. The firm undertook design, construction and manufacture of the ironwork for the Deepdale viaduct (b.1857-1860) on the Stainmore Railway Company to a design of Thomas Bouch and Robert Henry Bow. In 1875, the name changed again to the Tees-side Iron and Engine Works Company Limited, having built 351 locomotives in total. Subsequently the firm worked with Bouch on the Tay Bridge, and had their reputation very badly damaged as a result of the Tay Bridge Disaster. The 1870s Long Depression forced several Cleveland iron firms out of busines ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tie (engineering)
A tie, strap, tie rod, eyebar, guy-wire, suspension cables, or wire ropes, are examples of linear structural components designed to resist tension. It is the opposite of a strut or column, which is designed to resist compression. Ties may be made of any tension resisting material. Application in wood construction In wood-frame construction ties are generally made of galvanized steel. Wood framing ties generally have holes allowing them to be fastened to the wood structure by nails or screws. The number and type of nails are specific to the tie and its use. The manufacturer generally specifies information as to the connection method for each of their products. Among the most common wood framing ties used is the hurricane tie or seismic tie used in the framing of wooden structures where wind uplift or seismic overturning is a concern. Hurricane tie A hurricane tie is used to help make a structure (specifically wooden structures) more resistant to high winds (such as in ...
