James Meadows Rendel (engineer)
James Meadows Rendel FRS (December 1799 – 21 November 1856) was a British civil engineer. Early life and career Rendel was the son of the surveyor James Rendel or Rendle and his wife Jane, daughter of the architect John Meadows (died 1791); he was born near Okehampton, Devon, in 1799. He was initiated into the operations of a millwright under an uncle at Teignmouth, while from his father he learnt some civil engineering. At an early age he went to London as a surveyor under Thomas Telford, by whom he was employed on the surveys for the proposed suspension bridge across the Mersey at Runcorn. About 1822 he settled at Plymouth, and commenced the construction of roads in the north of Devon. One of his smaller projects, still surviving, was an 1826 bridge over Bowcombe Creek on the Kingsbridge Estuary. In August 1824 he was employed by the Earl of Morley in making a bridge across the Catwater, an estuary of the Plym within the harbour of Plymouth at Laira. To guard against the u ...

William Boxall
Sir William Boxall (29 June 1800 – 6 December 1879) was an English painter and museum director. Early life and education He was born at Oxford on 29 June 1800, and baptised 29 July at St Michael's Church, Oxford, to Thomas Boxall (d. 1847) and his wife Diana (nee Perrett, d.1841). He had an older sister Anne (1794–1846) and a younger sister Emma (1807–1850). He was educated at John Roysse's Free School in Abingdon-on-Thames (now Abingdon School), before entering the Royal Academy Schools in 1819. Career Between 1827 and 1845 he made a number of trips to Italy to study the old masters. Initially hoping to make his name as a history painter, Boxall later had to turn to the more lucrative genre of portraiture. Among his friends were William Wordsworth, whose portrait he painted, the sculptor John Gibson and the painter Sir Edwin Landseer. He was the executor of the will of Sir Charles Lock Eastlake, his predecessor as Director of the National Gallery. Following his app ...

River Plym
The River Plym is a river in Devon, England. It runs from Dartmoor in the centre of the county southwest to meet the River Meavy, then south towards Plymouth Sound. The river is popular with canoeists, and the Plym Valley Railway runs alongside a section of the river. Course The river's source is around above sea level on Dartmoor, in an upland marshy area called Plym Head. From the upper reaches, which contain antiquities and mining remains, the river flows roughly southwest past clay workings at Shaugh Prior to The Dewerstone, where it meets the River Meavy. The course then changes to run southwards, between Plymouth and Plympton passing through the National Trust owned Plymbridge Woods and under the ancient Plym Bridge. Its upper tidal estuary is known as the Laira and the lower part is called Cattewater, which is navigable and leads towards Plymouth Sound. It is approximately long. Nomenclature The name Plym is thought to have its origins in Old English and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Tamar
The Tamar (; kw, Dowr Tamar) is a river in south west England, that forms most of the border between Devon (to the east) and Cornwall (to the west). A part of the Tamar Valley is a World Heritage Site due to its historic mining activities. The Tamar's source is less than from the north Cornish coast, but it flows southward and its course runs across the peninsula to the south coast. The total length of the river is . At its mouth, the Tamar flows into the Hamoaze before entering Plymouth Sound, a bay of the English Channel. Tributaries of the river include the rivers Inny, Ottery, Kensey and Lynher (or ''St Germans River'') on the Cornish side, and the Deer and Tavy on the Devon side. The name Tamar (or Tamare) was mentioned by Ptolemy in the second century in his ''Geography''. The name is said to mean "great water."Furneaux, Robert. The Tamar: A Great Little River.

Torpoint
Torpoint ( kw, Penntorr) is a civil parish and town on the Rame Peninsula in southeast Cornwall, England, United Kingdom. It is situated opposite the city of Plymouth across the Hamoaze which is the tidal estuary of the River Tamar. Torpoint had a population of 8,457 at the 2001 census, decreasing to 8,364 at the 2011 census. Two electoral wards also exist ( Torpoint East and Torpoint West). Their combined populations at the same census were 7,717. Torpoint is linked to Plymouth (and Devonport) by the Torpoint Ferry. The three vessels that operate the service are chain ferries – that is, they are propelled across the river by pulling themselves on fixed chains which lie across the bed of the river. The journey takes about seven minutes. Origin of name It is said that Torpoint's name is derived from Tar Point, a name given because of the initial industry on the west bank of the Hamoaze. However this is actually a nickname given by workers, Torpoint meaning "rocky headl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dartmouth, Devon
Dartmouth () is a town and civil parish in the English county of Devon. It is a tourist destination set on the western bank of the estuary of the River Dart, which is a long narrow tidal ria that runs inland as far as Totnes. It lies within the South Devon Area of Outstanding Natural Beauty and South Hams district, and had a population of 5,512 in 2001, reducing to 5,064 at the 2011 census. There are two electoral wards in the ''Dartmouth'' area (Townstal & Kingswear). Their combined population at the above census was 6,822. History In 1086, the Domesday Book listed ''Dunestal'' as the only settlement in the area which now makes up the parish of Dartmouth. It was held by Walter of Douai. It paid tax on half a hide, and had two plough teams, two slaves, five villagers and four smallholders. There were six cattle, 40 sheep and 15 goats. At this time Townstal (as the name became) was apparently a purely agricultural settlement, centred around the church. Walter of Douai rebel ...

River Dart
The River Dart is a river in Devon, England, that rises high on Dartmoor and flows for to the sea at Dartmouth. Name Most hydronyms in England derive from the Brythonic language (from which the river's subsequent names ultimately derive from an original Celtic etymology. As the lower stretches of the river are still covered in ancient oak woodlands, it is accepted that the first element derives from *Dar-, meaning oak (derow'', Welsh ''derw''). However the second element (evident in the hard consonantal termination of ''Dar-t'') is less certain, with postulated etymologies from ''Darwent'' / ''Derventio'' (Sacred place of Oak) or ''Darnant'' / ''Darant'' (Oak stream). The Ravenna Cosmography records a number of Latinised names for the area, ''Devionisso Statio'' and ''Deventiasteno'' may represent corrupted doublets of a ''Statio'' (Station) on a river named ''Derventio''. Although the name ''Derventio'' is otherwise unattested for the river, it is an established etymolo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pontoon Bridge
A pontoon bridge (or ponton bridge), also known as a floating bridge, uses floats or shallow-draft boats to support a continuous deck for pedestrian and vehicle travel. The buoyancy of the supports limits the maximum load that they can carry. Most pontoon bridges are temporary and used in wartime and civil emergencies. There are permanent pontoon bridges in civilian use that can carry highway traffic. Permanent floating bridges are useful for sheltered water crossings if it is not considered economically feasible to suspend a bridge from anchored piers. Such bridges can require a section that is elevated or can be raised or removed to allow waterborne traffic to pass. Pontoon bridges have been in use since ancient times and have been used to great advantage in many battles throughout history, such as the Battle of Garigliano, the Battle of Oudenarde, the crossing of the Rhine during World War II, the Iran–Iraq War's Operation Dawn 8, and most recently, in the 2022 Russian ...

Cable Ferry
A cable ferry (including the terms chain ferry, swing ferry, floating bridge, or punt) is a ferry that is guided (and in many cases propelled) across a river or large body of water by cables connected to both shores. Early cable ferries often used either rope or steel chains, with the latter resulting in the alternative name of chain ferry. Both of these were largely replaced by wire cable by the late 19th century. Types There are three types of cable ferry: the reaction ferry, which uses the power of the river to tack across the current; the powered cable ferry, which uses engines or electric motors (e.g., the Canby Ferry in the U.S. State of Oregon) to wind itself across; and the hand-operated type, such as the Stratford-upon-Avon chain ferry in the UK and the Saugatuck Chain Ferry in Saugatuck, Michigan, United States. Powered cable ferries use powered wheels or drums on board the vessel to pull itself along by the cables. The chains or wire ropes can be used with a su ...

Swing Bridge
A swing bridge (or swing span bridge) is a movable bridge that has as its primary structural support a vertical locating pin and support ring, usually at or near to its center of gravity, about which the swing span (turning span) can then pivot horizontally as shown in the animated illustration to the right. Small swing bridges as found over canals may be pivoted only at one end, opening as would a gate, but require substantial underground structure to support the pivot. In its closed position, a swing bridge carrying a road or railway over a river or canal, for example, allows traffic to cross. When a water vessel needs to pass the bridge, road traffic is stopped (usually by traffic signals and barriers), and then motors rotate the bridge horizontally about its pivot point. The typical swing bridge will rotate approximately 90 degrees, or one-quarter turn; however, a bridge which intersects the navigation channel at an oblique angle may be built to rotate only 45 degrees, or ...

Fluid Power
Fluid power is the use of fluids under pressure to generate, control, and transmit power. Fluid power is subdivided into hydraulics using a liquid such as mineral oil or water, and pneumatics using a gas such as air or other gases. Compressed-air and water-pressure systems were once used to transmit power from a central source to industrial users over extended geographic areas; fluid power systems today are usually within a single building or mobile machine. Fluid power systems perform work by a pressurized fluid bearing directly on a piston in a cylinder or in a fluid motor. A fluid cylinder produces a force resulting in linear motion, whereas a fluid motor produces torque resulting in rotary motion. Within a fluid power system, cylinders and motors (also called actuators) do the desired work. Control components such as valves regulate the system. Elements A fluid power system has a pump driven by a prime mover (such as an electric motor or internal combustion engine) th ...

Kingsbridge
Kingsbridge is a market town and tourist hub in the South Hams district of Devon, England, with a population of 6,116 at the 2011 census. Two electoral wards bear the name of ''Kingsbridge'' (East & North). Their combined population at the above census was 4,381. It is situated at the northern end of the Kingsbridge Estuary, a ria that extends to the sea six miles south of the town. It is the third largest settlement in the South Hams and is 17 miles (27 km) southwest of Torquay and 17 miles (27 km) southeast of Plymouth. History The town formed around a bridge which was built in or before the 10th century between the royal estates of Alvington, to the west, and Chillington, to the east, hence giving it the name of Kyngysbrygge ("King's bridge"). In 1219W. G. Hoskins, ''Devon'', 1954 the Abbot of Buckfast was granted the right to hold a market there, and by 1238 the settlement had become a borough. The manor remained in possession of the abbot until the Diss ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
