Lady Elliot Island Light
Lady Elliot Island Light is an active lighthouse located on Lady Elliot Island, the southernmost coral cay of the Great Barrier Reef, north-east of Bundaberg, Queensland, Australia. The lighthouse is located on the western side of the island. It was the third lighthouse erected in Queensland after its formation in 1859 and the first in Australia to be constructed of a timber frame clad with iron plates. The original lighthouse was deactivated in 1995 and the light was replaced by a modern skeletal tower standing close to the original lighthouse. History Establishment The Government of Queensland was formed in 1859. In 1862, the Queensland government appointed the first Portmaster, Commander George Poynter Heath. However, it was only in 1864 that two committees were appointed to deal with the issue of coastal lighthouses. Lady Elliot Island was one of the locations mentioned by the committees as a possible suitable site for the construction of a lighthouse. The first navigati ...

Lady Elliot Island
Lady Elliot Island is the southernmost coral cay of the Great Barrier Reef, Australia. The island lies north-east of Bundaberg and covers an area of approximately . It is part of the Capricorn and Bunker Group of islands and is owned by the Commonwealth of Australia. The island is home to a small eco resort and an airstrip, which is serviced daily by flights from Bundaberg, Hervey Bay, Brisbane and the Gold Coast. Lady Elliot Island is located within the 'Green Zone' of the Great Barrier Reef Marine Park, which is the highest possible classification designated by the Great Barrier Reef Marine Park Authority. Marine National Park Green Zones protect the biodiversity within the Great Barrier Reef Marine Park by protecting important breeding and nursery areas such as seagrass beds, mangrove communities, deepwater shoals and reefs. The island is particularly renowned for its scuba diving and snorkelling, as its location far offshore at the southern end of the Great Barrier Reef r ...

Cowan Cowan Point Light
Cowan Cowan Point Light, was also known as Cowan Cowan Light or Cowan Point Light, was located on Cowan Cowan Point, on the western shore of Moreton Island, Queensland, Australia. History The first settlement at the point was a pilot station, moved from Amity Point in August 1848. The pilot station was later moved to Bulwer. The first lighthouse was constructed in the early 1860s, a wooden tower. It carried a large kerosene burner with a reflector and showed a fixed white light. In 1867, together with the construction of the Comboyuro Point Light tower, the tower was extended to . In 1873 it was decided that the tower should be upgraded again. The new lighthouse was constructed in 1874 by the brothers John and Jacob Rooney of Maryborough, Queensland, Maryborough, who already constructed Sandy Cape Light in 1870. The Rooney brother also constructed Lady Elliot Island Light around the same time, and the same lantern plan was used for both lighthouses. They later constructed Ca ...

Candela
The candela ( or ; symbol: cd) is the unit of luminous intensity in the International System of Units (SI). It measures luminous power per unit solid angle emitted by a light source in a particular direction. Luminous intensity is analogous to radiant intensity, but instead of simply adding up the contributions of every wavelength of light in the source's spectrum, the contribution of each wavelength is weighted by the standard luminosity function (a model of the sensitivity of the human eye to different wavelengths). A common wax candle emits light with a luminous intensity of roughly one candela. If emission in some directions is blocked by an opaque barrier, the emission would still be approximately one candela in the directions that are not obscured. The word ''candela'' is Latin for ''candle''. The old name "candle" is still sometimes used, as in ''foot-candle'' and the modern definition of ''candlepower''.

Prefabrication
Prefabrication is the practice of assembling components of a structure in a factory or other manufacturing site, and transporting complete assemblies or sub-assemblies to the construction site where the structure is to be located. The term is used to distinguish this process from the more conventional construction practice of transporting the basic materials to the construction site where all assembly is carried out. The term ''prefabrication'' also applies to the manufacturing of things other than structures at a fixed site. It is frequently used when fabrication of a section of a machine or any movable structure is shifted from the main manufacturing site to another location, and the section is supplied assembled and ready to fit. It is not generally used to refer to electrical or electronic components of a machine, or mechanical parts such as pumps, gearboxes and compressors which are usually supplied as separate items, but to sections of the body of the machine which in the ...

Wrought Iron
Wrought iron is an iron alloy with a very low carbon content (less than 0.08%) in contrast to that of cast iron (2.1% to 4%). It is a semi-fused mass of iron with fibrous slag Inclusion (mineral), inclusions (up to 2% by weight), which give it a wood-like "grain" that is visible when it is etched, rusted, or bent to structural failure, failure. Wrought iron is tough, malleable, ductile, corrosion resistant, and easily forge welding, forge welded, but is more difficult to welding, weld electrically. Before the development of effective methods of steelmaking and the availability of large quantities of steel, wrought iron was the most common form of malleable iron. It was given the name ''wrought'' because it was hammered, rolled, or otherwise worked while hot enough to expel molten slag. The modern functional equivalent of wrought iron is Carbon steel#Mild or low-carbon steel, mild steel, also called low-carbon steel. Neither wrought iron nor mild steel contain enough carbon to be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Troubridge Island Lighthouse
Troubridge Island Lighthouse is a decommissioned lighthouse in the Australian state of South Australia located on Troubridge Island in Gulf St Vincent about southwest of the state capital of Adelaide and about southeast by east of Edithburgh on Yorke Peninsula. History The lighthouse was commissioned in 1856 as a means to reduce losses caused by the stranding of ships on the Troubridge Shoals. Czech-born surrealist artist Voitre Marek, who had migrated to Adelaide in 1949, lived with his wife and young children as lighthouse keeper at Troubridge Island from 1957 until 1960, after moving from the Cape du Couedic Lighthouse after that lighthouse was automated and demanned. The lighthouse was converted to automatic operation in 1981 and decommissioned in 2001. Its role as a navigation aid was taken over progressively from 1980 by the new Troubridge Hill Lighthouse, located on Troubridge Hill, to the west of the Troubridge Shoals. In 1978, the lighthouse was listed on the now- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bolted Joint
A bolted joint is one of the most common elements in construction and machine design. It consists of a male threaded fastener (e. g., a bolt) that captures and joins other parts, secured with a matching female screw thread. There are two main types of bolted joint designs: tension joints and shear joints. Joint types In a tension joint, the bolt and clamped components of the joint are designed to transfer an applied tension load through the joint by way of the clamped components by the design of a proper balance of joint and bolt stiffness. The joint should be designed such that the clamp load is never overcome by the external tension forces acting to separate the joint. If the external tension forces overcome the clamp load (bolt preload) the clamped joint components will separate, allowing relative motion of the components. The second type of bolted joint transfers the applied load in shear of the bolt shank and relies on the shear strength of the bolt. Tension loads on such ...

Bustard Head Light
Bustard Head Light is an active lighthouse located on the southeast tip of Bustard Head, a headland, about northwest of Seventeen Seventy, in the Australian state of Queensland, within the Eurimbula National Park and locality of Eurimbula. Built in 1868, it is the second-oldest lightstation in the state, following Cape Moreton Light, and the first to be built in Queensland after its formation in 1859. It is also one of the first in Australia to be constructed using bolted prefabricated segments of cast iron, and one of only two such lighthouses in Queensland, the other being its sibling, Sandy Cape Light. It serves as the central relay for Dent Island Light, Pine Islet Light and Lady Elliot Island Light and as the radio check post for Cape Capricorn Light, Sandy Cape Light and Double Island Point Light. Bustard Head was named by Captain James Cook in 1770, in honour of a bustard which was shot and eaten by the landing party at the location. History The Government of Queen ...
