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 disast ... [...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, the b ...

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 th ...

Share (finance)
In finance, financial markets, a share is a unit of Equity (finance), 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 principle ... [...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).
