Winding Hole
A winding hole () is a widened area of a canal (usually in the United Kingdom), used for turning a canal boat such as a narrowboat. In sea ports an area for turning ships is usually called a turning basin. Etymology The word is commonly believed to derive from the practice of using the wind to assist with the turn. Another etymology, however, is the Old English word for turn - "windan", (pronounced with a short I (as in windlass, a handle for winding (long I) gears)). Much UK canal terminology comes from spoken rather than written tradition and from bargees who did not read or write. It is also possible that the word has a similar derivation to that of the windlass, which derives from the Old Norse Old Norse, also referred to as Old Nordic or Old Scandinavian, was a stage of development of North Germanic languages, North Germanic dialects before their final divergence into separate Nordic languages.

Winding Hole On The Worcester And Birmingham Canal
An electromagnetic coil is an electrical conductor such as a wire in the shape of a coil (spiral or helix). Electromagnetic coils are used in electrical engineering, in applications where electric currents interact with magnetic fields, in devices such as electric motors, generators, inductors, electromagnets, transformers, sensor coils such as in medical MRI imaging machines. Either an electric current is passed through the wire of the coil to generate a magnetic field, or conversely, an external ''time-varying'' magnetic field through the interior of the coil generates an EMF (voltage) in the conductor. A current through any conductor creates a circular magnetic field around the conductor due to Ampere's law. The advantage of using the coil shape is that it increases the strength of the magnetic field produced by a given current. The magnetic fields generated by the separate turns of wire all pass through the center of the coil and add ( superpose) to produce a strong ...

Canal
Canals or artificial waterways are waterways or engineered channels built for drainage management (e.g. flood control and irrigation) or for conveyancing water transport vehicles (e.g. water taxi). They carry free, calm surface flow under atmospheric pressure, and can be thought of as artificial rivers. In most cases, a canal has a series of dams and locks that create reservoirs of low speed current flow. These reservoirs are referred to as ''slack water levels'', often just called ''levels''. A canal can be called a navigation canal when it parallels a natural river and shares part of the latter's discharges and drainage basin, and leverages its resources by building dams and locks to increase and lengthen its stretches of slack water levels while staying in its valley. A canal can cut across a drainage divide atop a ridge, generally requiring an external water source above the highest elevation. The best-known example of such a canal is the Panama Can ...

Narrowboat
A narrowboat is a particular type of Barge, canal boat, built to fit the narrow History of the British canal system, locks of the United Kingdom. The UK's canal system provided a nationwide transport network during the Industrial Revolution, but with the advent of the railways, commercial canal traffic gradually diminished and the last regular long-distance transportation of goods by canal had virtually disappeared by 1970. However, some commercial traffic continued. From the 1970s onward narrowboats were gradually being converted into permanent residences or as holiday lettings. Currently, about 8,580 narrowboats are registered as 'permanent homes' on Britain's waterway system and represent a growing alternative community living on semi-permanent moorings or continuously cruising. For any boat to enter a narrow lock, it must be under wide, so most narrowboats are nominally wide. A narrowboat's maximum length is generally , as anything longer will be unable to navigate much ...

Turning Basin
A turning basin, winding basin or swinging basin is a wider body of water, either located at the end of a ship canal or in a port to allow cargo ships to turn and reverse their direction of travel, or to enable long narrow barges in a canal to turn a sharp corner. For a complete 180-degree turnaround, the width of the basin must be more than the length of the longest vessel normally traversing the waterway. Onboard bow thrusters or tugboats may assist in manoeuvering the ship. In seaports the turning basin is often not a real physical basin, but a designated area in the harbour basin where turning is possible and mooring is prohibited. In the example from Gdynia the plan is to enlarge the existing turning basin by removing a part of an existing quay (shown in red in the image). Dimensions PIANC guideline 141 recommends a turning basin diameter for channels of 1.2 times the ship's length; in China, twice the ship's length is used.

Old English
Old English ( or , or ), or Anglo-Saxon, is the earliest recorded form of the English language, spoken in England and southern and eastern Scotland in the Early Middle Ages. It developed from the languages brought to Great Britain by Anglo-Saxon settlers in the mid-5th century, and the first Old English literature dates from the mid-7th century. After the Norman Conquest of 1066, English was replaced for several centuries by Anglo-Norman language, Anglo-Norman (a langues d'oïl, type of French) as the language of the upper classes. This is regarded as marking the end of the Old English era, since during the subsequent period the English language was heavily influenced by Anglo-Norman, developing into what is now known as Middle English in England and Early Scots in Scotland. Old English developed from a set of Anglo-Frisian or Ingvaeonic dialects originally spoken by Germanic tribes traditionally known as the Angles (tribe), Angles, Saxons and Jutes. As the Germanic settlers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windlass
The windlass is an apparatus for moving heavy weights. Typically, a windlass consists of a horizontal cylinder (barrel), which is rotated by the turn of a crank or belt. A winch is affixed to one or both ends, and a cable or rope is wound around the winch, pulling a weight attached to the opposite end. The Greek scientist Archimedes was the inventor of the windlass. A surviving medieval windlass, dated to –1400, is in the Church of St Mary and All Saints, Chesterfield. The oldest depiction of a windlass for raising water can be found in the Book of Agriculture published in 1313 by the Chinese official Wang Zhen (inventor), Wang Zhen of the Yuan Dynasty ( 1290–1333). Uses * Vitruvius, a military engineer writing about 28 BC, defined a machine as "a combination of timber fastened together, chiefly efficacious in moving great weights". About a century later, Hero of Alexandria summarized the practice of his day by naming the "five simple machines" for "moving a given ...

Old Norse
Old Norse, also referred to as Old Nordic or Old Scandinavian, was a stage of development of North Germanic languages, North Germanic dialects before their final divergence into separate Nordic languages. Old Norse was spoken by inhabitants of Scandinavia and their Viking expansion, overseas settlements and chronologically coincides with the Viking Age, the Christianization of Scandinavia, and the consolidation of Scandinavian kingdoms from about the 8th to the 15th centuries. The Proto-Norse language developed into Old Norse by the 8th century, and Old Norse began to develop into the modern North Germanic languages in the mid- to late 14th century, ending the language phase known as Old Norse. These dates, however, are not precise, since written Old Norse is found well into the 15th century. Old Norse was divided into three dialects: Old West Norse (Old West Nordic, often referred to as ''Old Norse''), Old East Norse (Old East Nordic), and Old Gutnish. Old West Norse and O ...

Towpath
A towpath is a road or trail on the bank of a river, canal, or other inland waterway. The purpose of a towpath is to allow a land vehicle, Working animal, beasts of burden, or a team of human pullers to tow a boat, often a barge. This mode of transport was common where sailing was impractical because of tunnels and bridges, unfavorable winds, or the narrowness of the channel. After the Industrial Revolution, towing became obsolete when engines were fitted on boats and when railway transportation superseded the slow towing method. Since then, many of these towpaths have been converted to Multi-use trail#Multi-use trails, multi-use trails and footpaths. They are still named towpaths — although they are now only occasionally used for the purpose of towing boats. History Early inland waterway transport used the rivers, and while barges could use sails to assist their passage when winds were favourable or the river was wide enough to allow tacking, in many cases this was not ...

History Of The British Canal System
The canal network of the United Kingdom of Great Britain and Ireland, United Kingdom played a vital role in the Industrial Revolution. The UK was the first country to develop a nationwide canal network which, at its peak, expanded to nearly in length. The canals allowed raw materials to be transported to a place of manufacture, and finished goods to be transported to consumers, more quickly and cheaply than by a land based route. The canal network was extensive and included feats of civil engineering such as the Anderton Boat Lift, the Manchester Ship Canal, the Worsley Navigable Levels and the Pontcysyllte Aqueduct. In the post-medieval period, some rivers were canalised for boat traffic. The Exeter Ship Canal was completed in 1567. The Sankey Canal was the first British canal of the Industrial Revolution, opening in 1757. The Bridgewater Canal followed in 1761 and proved to be highly profitable. The majority of the network was built in the "Golden Age" of canals, between the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
