Currie Lighthouse
Currie Lighthouse was built following agitation by Archibald Currie and others for a lighthouse at Currie Harbour, Currie, King Island, Australia in 1879. Planned and fabricated by Chance Brothers in Smethwick, England, it was devised as a -tall square pyramidal truss iron tower with an iron cylinder centred inside, and then shipped to Tasmania to be erected. After an inactive period from 1989 to 1995, the light is now active again. The light characteristic is "Fl. 6 s", i.e. one flash every six seconds. The lightsource's focal plane is situated above sea level. The adjacent keeper's house was turned into a museum in 1980.

Currie, Tasmania
Currie is a rural residential locality in the local government area (LGA) of King Island in the North-west and west LGA region of Tasmania. The 2016 census recorded a population of 768 for the state suburb of Currie. It is the largest township on, and is the administrative centre of, King Island, at the western entrance to Bass Strait. History Currie was gazetted as a locality in 1971. Geography The waters of the Southern Ocean form the western and south-western boundaries. The town is situated just inland from a partly sheltered natural harbour on the west coast of the island, which was originally named Howie's Boat Harbour after David Howie, an early visitor and unofficial resident of the island in the 1840s. It was renamed after Archibald Currie (1830–1914), a Melbourne shipowner who purchased the remains of the full-rigged ship '' Netherby'' wrecked near there in 1866, and used the harbour as a base for salvage operations. The harbour was used for similar operations o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smethwick
Smethwick () is an industrial town in Sandwell, West Midlands, England. It lies west of Birmingham city centre. Historically it was in Staffordshire. In 2019, the ward of Smethwick had an estimated population of 15,246, while the wider built-up area subdivision has a population of 53,653. History It was suggested that the name Smethwick meant "smiths' place of work", but a more recent interpretation has suggested the name means "the settlement on the smooth land". Smethwick was recorded in the Domesday Book as ''Smedeuuich'', the ''d'' in this spelling being the Anglo-Saxon letter eth. Until the end of the 18th century it was an outlying hamlet of the south Staffordshire village of Harborne. Harborne became part of the county borough of Birmingham and thus transferred from Staffordshire to Warwickshire in 1891, leaving Smethwick in the County of Staffordshire. The world's oldest working engine, the Smethwick Engine, made by Boulton & Watt, originally stood near Br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lighthouses Completed In 1879
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lenses and to serve as a beacon for navigational aid, for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, reefs, rocks, and safe entries to harbors; they also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and has become uneconomical since the advent of much cheaper, more sophisticated and effective electronic navigational systems. History Ancient lighthouses Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since elevating the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signal for reefs a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Lighthouses In Australia
This is a list of lighthouses and lightvessels in Australia. Australia has a coastline of , with over 350 lighthouses and navigational aids around the Australian coastline, and a single inland lighthouse, the Point Malcolm lighthouse. The first lighthouse was Macquarie Lighthouse, which was lit in 1793 as a tripod mounted wood and coal fired beacon. The last staffed lighthouse was Maatsuyker Island Lighthouse, off the south coast of Tasmania, which was automated in 1996. Listing The lighthouses and lightvessels of Australia are listed in the National Geospatial-Intelligence Agency ''List of Lights'' publication 111. They are listed by the United Kingdom Hydrographic Office on volume K of the ''Admiralty List of Lights & Fog Signals''. The ''ARLHS World List of Lights'' lists them with the prefix "AUS". On ''The Lighthouse Directory'', the lighthouses of Australia are listed according to their location: * Coral Sea Islands Territory * New South Wales, including Cape St George ...

History Of Tasmania
The history of Tasmania begins at the end of the most recent ice age (approximately 10,000 years ago) when it is believed that the island was joined to the Australian mainland. Little is known of the human history of the island until the British colonisation in the 19th century. Indigenous people Tasmania was inhabited by an Indigenous population, the Aboriginal Tasmanians, and evidence indicates their presence in the territory, later to become an island, at least 35,000 years ago. At the time of the British occupation and colonisation in 1803 the Indigenous population was estimated at between 3000 and 10,000. Historian Lyndall Ryan's analysis of population studies led her to conclude that there were about 7000 spread throughout the island's nine nations; Nicholas Clements, citing research by N.J.B. Plomley and Rhys Jones, settled on a figure of 3000 to 4000. The combination of the so-called Black War, internecine conflict and, from the late 1820s, the spread of infectious ...

Focal Plane
In Gaussian optics, the cardinal points consist of three pairs of points located on the optical axis of a rotationally symmetric, focal, optical system. These are the '' focal points'', the principal points, and the nodal points. For ''ideal'' systems, the basic imaging properties such as image size, location, and orientation are completely determined by the locations of the cardinal points; in fact only four points are necessary: the focal points and either the principal or nodal points. The only ideal system that has been achieved in practice is the plane mirror, however the cardinal points are widely used to ''approximate'' the behavior of real optical systems. Cardinal points provide a way to analytically simplify a system with many components, allowing the imaging characteristics of the system to be approximately determined with simple calculations. Explanation The cardinal points lie on the optical axis of the optical system. Each point is defined by the effect the opti ...

Light Characteristic
A light characteristic is all of the properties that make a particular navigational light identifiable. Graphical and textual descriptions of navigational light sequences and colours are displayed on nautical charts and in Light Lists with the chart symbol for a lighthouse, lightvessel, buoy or sea mark with a light on it. Different lights use different colours, frequencies and light patterns, so mariners can identify which light they are seeing. Abbreviations While light characteristics can be described in prose, e.g. "Flashing white every three seconds", lists of lights and navigation chart annotations use abbreviations. The abbreviation notation is slightly different from one light list to another, with dots added or removed, but it usually follows a pattern similar to the following (see the chart to the right for examples). * An abbreviation of the type of light, e.g. "Fl." for flashing, "F." for fixed. * The color of the light, e.g. "W" for white, "G" for green, "R" for red, ...

Truss
A truss is an assembly of ''members'' such as beams, connected by ''nodes'', that creates a rigid structure. In engineering, a truss is a structure that "consists of two-force members only, where the members are organized so that the assemblage as a whole behaves as a single object". A "two-force member" is a structural component where force is applied to only two points. Although this rigorous definition allows the members to have any shape connected in any stable configuration, trusses typically comprise five or more triangular units constructed with straight members whose ends are connected at joints referred to as ''nodes''. In this typical context, external forces and reactions to those forces are considered to act only at the nodes and result in forces in the members that are either tensile or compressive. For straight members, moments (torques) are explicitly excluded because, and only because, all the joints in a truss are treated as revolutes, as is necessary for ...

Chance Brothers
Chance Brothers and Company was a glassworks originally based in Spon Lane, Smethwick, West Midlands (formerly in Staffordshire), in England. It was a leading glass manufacturer and a pioneer of British glassmaking technology. The Chance family originated in Bromsgrove in Worcestershire as farmers and craftsmen, before setting up business in Smethwick in 1822. Situated between Birmingham and the Black Country in the agglomeration of the Midlands industrial heartland, they took advantage of the skilled workers, canals and many advances that were taking place in the industrial West Midlands at the time. Throughout its almost two centuries of history many changes affected the company which, now privatised, continues to function as Chance Glass Limited, a specialised industrial glass manufacturer in Malvern, Worcestershire at one of its small subsidiary factories. The social and economic impact of the company on the region is the subject of a project sponsored by the Heritage Lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
King Island (Tasmania)
King Island is an island in the Bass Strait, belonging to the Australian state of Tasmania. It is the largest of three islands known as the New Year Group, and the second-largest island in Bass Strait (after Flinders Island). The island's population at the was 1,585 people, up from 1,566 in 2011. The local government area of the island is the King Island Council. The island forms part of the official land divide between the Great Australian Bight and Bass Strait, off the north-western tip of Tasmania and about halfway to the mainland state of Victoria. The southernmost point is Stokes Point and the northernmost point is Cape Wickham. There are three small islands immediately offshore: New Year Island and Christmas Island situated to the northwest, and a smaller island Councillor Island to the east, opposite Sea Elephant Beach. King Island was first visited by Europeans in the late 18th century. It was named after Philip Gidley King, Colonial Governor of New South Wales, who ...

Currie Harbour-King Island-Australia
Currie ( gd, Currach, IPA: kʰuːᵲəx is a village and suburb on the outskirts of Edinburgh, Scotland, situated south west of the city centre. Formerly within the County of Midlothian, it now falls within the jurisdiction of the City of Edinburgh Council. It is situated between Juniper Green to the northeast and Balerno to the southwest. It gives its name to a civil parish. In 2001, the population of Currie was 8,550 and it contained 3,454 houses. Etymology The name is recorded from 1210 onwards under various spellings such as ''Curey'', ''Cory'', ''Curri'' with ''Currie'' in 1402. There is no accepted derivation of the name Currie but it is possibly from the Scottish Gaelic word ''curagh/curragh'', a wet or boggy plain, or from the Brythonic word ''curi'', a dell or dirt hole. The neighbouring suburb of Balerno derives its name from Scottish Gaelic, whilst the nearby Pentland Hills derive their name from Brythonic, so either is possible. History The earliest ...
