Edward Woods (engineer)
Edward Woods FRSA (28 April 1814 – 14 June 1903) was a British civil engineer. Early life and career Woods was born in London on 28 April 1814, the son of Samuel Woods, a merchant. His younger brother, Joseph Woods was also an engineer and in 1844 became a founding partner of Dewrance & Co. Ltd. After education at private schools, and some training at Bristol, he became in 1834 an assistant to John Dixon, recently appointed chief engineer of the Liverpool and Manchester Railway. Woods was placed in charge of the section, 15 miles in length, between Liverpool and Newton-le-Willows, including Wapping Tunnel between the Cavendish cutting and Park Lane goods stations; and in 1836 he succeeded Dixon as chief engineer, taking also charge of the mechanical department. The Liverpool and Manchester railway was amalgamated with the Grand Junction Railway in 1845. Woods remained until the end of 1852 in charge of the works appertaining to the Liverpool and Manchester section, inclu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Civil Engineering
Civil engineering is a professional engineering discipline that deals with the design, construction, and maintenance of the physical and naturally built environment, including public works such as roads, bridges, canals, dams, airports, sewage systems, pipelines, structural components of buildings, and railways. Civil engineering is traditionally broken into a number of sub-disciplines. It is considered the second-oldest engineering discipline after military engineering, and it is defined to distinguish non-military engineering from military engineering. Civil engineering can take place in the public sector from municipal public works departments through to federal government agencies, and in the private sector from locally based firms to global Fortune 500 companies. History Civil engineering as a discipline Civil engineering is the application of physical and scientific principles for solving the problems of society, and its history is intricately linked to advances in t ...

Liverpool Docks
The Port of Liverpool is the enclosed dock system that runs from Brunswick Dock in Liverpool to Seaforth Dock, Seaforth, on the east side of the River Mersey and the Birkenhead Docks between Birkenhead and Wallasey on the west side of the river. The port was extended in 2016 by the building of an in-river container terminal at Seaforth Dock, named Liverpool2. The terminal can berth two 14,000 container Post-Panamax ships. Garston Docks, which are in the city of Liverpool, are not a part of the Port of Liverpool. The working docks are operated by Mersey Docks and Harbour Company, the docks to the south of the Pier Head are operated by the Canal & River Trust, the successor to former operator British Waterways. History Liverpool's first dock was the world's first enclosed commercial dock, the Old Dock, built in 1715. The Lyver Pool, a tidal inlet in the narrows of the estuary, which is now largely under the Liverpool One shopping centre, was converted into the e ...

Coke (fuel)
Coke is a grey, hard, and porous coal-based fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern. The unqualified term "coke" usually refers to the product derived from low-ash and low-sulphur bituminous coal by a process called coking. A similar product called petroleum coke, or pet coke, is obtained from crude oil in oil refineries. Coke may also be formed naturally by geologic processes.B. Kwiecińska and H. I. Petersen (2004): "Graphite, semi-graphite, natural coke, and natural char classification — ICCP system". ''International Journal of Coal Geology'', volume 57, issue 2, pages 99-116. History China Historical sources dating to the 4th century describe the production of coke in ancient China. The Chinese first used coke for heating ...

Rugby, Warwickshire
Rugby is a market town in eastern Warwickshire, England, close to the River Avon. In the 2021 census its population was 78,125, making it the second-largest town in Warwickshire. It is the main settlement within the larger Borough of Rugby which has a population of 114,400 (2021). Rugby is situated on the eastern edge of Warwickshire, near to the borders with Leicestershire and Northamptonshire. Rugby is the most easterly town within the West Midlands region, with the nearby county borders also marking the regional boundary with the East Midlands. It is north of London, east-southeast of Birmingham, east of Coventry, north-west of Northampton, and south-southwest of Leicester. Rugby became a market town in 1255, but remained a small and fairly unimportant town until the 19th century. In 1567 Rugby School was founded as a grammar school for local boys, but by the 18th century it had gained a national reputation as a public school. The school is the birthplace of Rugby foo ...

London And North Western Railway
The London and North Western Railway (LNWR, L&NWR) was a British railway company between 1846 and 1922. In the late 19th century, the L&NWR was the largest joint stock company in the United Kingdom. In 1923, it became a constituent of the London, Midland and Scottish (LMS) railway, and, in 1948, the London Midland Region of British Railways: the LNWR is effectively an ancestor of today's West Coast Main Line. History The company was formed on 16 July 1846 by the amalgamation of the Grand Junction Railway, London and Birmingham Railway and the Manchester and Birmingham Railway. This move was prompted, in part, by the Great Western Railway's plans for a railway north from Oxford to Birmingham. The company initially had a network of approximately , connecting London with Birmingham, Crewe, Chester, Liverpool and Manchester. The headquarters were at Euston railway station. As traffic increased, it was greatly expanded with the opening in 1849 of the Great Hall, designed by P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomas Tredgold
Thomas Tredgold (1788–1829) was an English engineer and author, known for his early work on railroad construction. His definition of civil engineering formed the basis of the charter of the Institution of Civil Engineers. Biography He was born at Brandon, County Durham, on 22 August 1788. After some elementary education at the village school, he was apprenticed at 14 to a cabinet-maker in Durham. He remained with him six years, studying also mathematics, architecture, and perspective. In 1808, after his apprenticeship had expired, he went to Scotland, where he worked for five years as a joiner and journeyman carpenter. Later Tredgold went to London, where he entered the office of his uncle William Atkinson the architect, with whom he lived for six years, and whom he served for longer. He read on architecture and engineering; and taught himself French. In 1823, the demands of his writing led Tredgold to resign his position in Atkinson's office. He died on 28 January 1829, ...

Telford Medal
The Telford Medal is a prize awarded by the British Institution of Civil Engineers (ICE) for a paper or series of papers. It was introduced in 1835 following a bequest made by Thomas Telford, the ICE's first president. It can be awarded in gold, silver or bronze; the Telford Gold Medal is the highest award the institution can bestow. History In 1834 Scottish civil engineer and the Institution of Civil Engineers' first president (1820-1834), Thomas Telford died, leaving in his will his library of technical works to the Institution of Civil Engineers, as well as a bequest of £2000; the interest from which was to be used to for the purpose of "Annual Premiums". The council of the institute decided to expend the premiums on both honorary and monetary rewards, the honorary awards being named Telford Medals, which would be awarded in gold, silver and bronze forms. Suitable candidates for the awards were submitters of drawings, models, diagrams or essays relating to civil engineering ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Locomotive
A locomotive or engine is a rail transport vehicle that provides the Power (physics), motive power for a train. If a locomotive is capable of carrying a payload, it is usually rather referred to as a multiple unit, Motor coach (rail), motor coach, railcar or power car; the use of these self-propelled vehicles is increasingly common for passenger trains, but rare for freight (see CargoSprinter). Traditionally, locomotives pulled trains from the front. However, Push-pull train, push-pull operation has become common, where the train may have a locomotive (or locomotives) at the front, at the rear, or at each end. Most recently railroads have begun adopting DPU or distributed power. The front may have one or two locomotives followed by a mid-train locomotive that is controlled remotely from the lead unit. __TOC__ Etymology The word ''locomotive'' originates from the Latin language, Latin 'from a place', Ablative case, ablative of 'place', and the Medieval Latin 'causing mot ...

Friction
Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: *Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact. Dry friction is subdivided into ''static friction'' ("stiction") between non-moving surfaces, and ''kinetic friction'' between moving surfaces. With the exception of atomic or molecular friction, dry friction generally arises from the interaction of surface features, known as asperities (see Figure 1). *Fluid friction describes the friction between layers of a viscous fluid that are moving relative to each other. *Lubricated friction is a case of fluid friction where a lubricant fluid separates two solid surfaces. *Skin friction is a component of drag, the force resisting the motion of a fluid across the surface of a body. *Internal friction is the force resisting motion between the elements making up a so ...

Gradient
In vector calculus, the gradient of a scalar-valued differentiable function of several variables is the vector field (or vector-valued function) \nabla f whose value at a point p is the "direction and rate of fastest increase". If the gradient of a function is non-zero at a point , the direction of the gradient is the direction in which the function increases most quickly from , and the magnitude of the gradient is the rate of increase in that direction, the greatest absolute directional derivative. Further, a point where the gradient is the zero vector is known as a stationary point. The gradient thus plays a fundamental role in optimization theory, where it is used to maximize a function by gradient ascent. In coordinate-free terms, the gradient of a function f(\bf) may be defined by: :df=\nabla f \cdot d\bf where ''df'' is the total infinitesimal change in ''f'' for an infinitesimal displacement d\bf, and is seen to be maximal when d\bf is in the direction of the gradi ...

Winding Engine
A winding engine is a stationary engine used to control a cable, for example to power a mining hoist at a pit head. Electric hoist controllers have replaced proper winding engines in modern mining, but use electric motors that are also traditionally referred to as ''winding engines''. Early winding engines were hand, or more usually horse powered. The first powered winding engines were stationary steam engines. The demand for winding engines was one factor that drove James Watt to develop his rotative beam engine, with its ability continuously to turn a winding drum, rather than the early reciprocating beam engines that were only useful for working pumps. They differ from most other stationary steam engines in that, like a steam locomotive, they need to be able to stop frequently and also reverse. This requires more complex valve gear and other controls than are needed on engines used in mills or to drive pump A pump is a device that moves fluids (liquids or gases), or ...

Fuel Efficiency
Fuel efficiency is a form of thermal efficiency, meaning the ratio of effort to result of a process that converts chemical potential energy contained in a carrier (fuel) into kinetic energy or work. Overall fuel efficiency may vary per device, which in turn may vary per application, and this spectrum of variance is often illustrated as a continuous energy profile. Non-transportation applications, such as industry, benefit from increased fuel efficiency, especially fossil fuel power plants or industries dealing with combustion, such as ammonia production during the Haber process. In the context of transport, fuel economy is the energy efficiency of a particular vehicle, given as a ratio of distance traveled per unit of fuel consumed. It is dependent on several factors including engine efficiency, transmission design, and tire design. In most countries, using the metric system, fuel economy is stated as "fuel consumption" in liters per 100 kilometers (L/100 km) or kilometer ...
