Williams River Bridge, Clarence Town
The Williams River bridge, Clarence Town is a heritage-listed road bridge that carries Limeburners Creek Road across the Williams River located in Clarence Town, New South Wales, Australia. It was designed by the New South Wales Public Works Department and built by J. K. McKenzie. The property is owned by Transport for NSW. It was added to the New South Wales State Heritage Register on 20 June 2000. History Timber truss bridges Timber truss road bridges have played a significant role in the expansion and improvement of the NSW road network. Prior to the bridges being built, river crossings were often dangerous in times of rain, which caused bulk freight movement to be prohibitively expensive for most agricultural and mining produce. Only the high priced wool clip of the time was able to carry the costs and inconvenience imposed by the generally inadequate river crossings that often existed prior to the trusses construction. Timber truss bridges were preferred by the NSW P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Williams River (New South Wales)
The Williams River is a perennial stream that is a tributary of the Hunter River, in the Hunter Region of New South Wales, Australia. Course and features The Williams River rises on the southern slopes of the Barrington Tops below Careys Peak within Barrington Tops National Park, and flows generally southeast and south, joined by ten tributaries including Chichester River, before reaching its confluence with the Hunter River at Raymond Terrace. The river descends over its course; through Dungog, Clarence Town and Seaham. At Clarence Town, the Williams River is crossed by the Clarence Town bridge that carries Limeburners Creek Road; and in Dungog, the river is crossed by the Cooreei Bridge that carries Stroud Hill Road. Both bridges are listed on the New South Wales State Heritage Register.

Australian Pound
The pound ( Sign: £, £A for distinction) was the currency of Australia from 1910 until 14 February 1966, when it was replaced by the Australian dollar. As with other £sd currencies, it was subdivided into 20 shillings (denoted by the symbol s or /–), each of 12 pence (denoted by the symbol d). History The establishment of a separate Australian currency was contemplated by section 51(xii) of the Constitution of Australia, which gave Federal Parliament the right to legislate with respect to "currency, coinage, and legal tender". Establishment Coinage The Deakin Government's ''Coinage Act 1909'' distinguished between "British coin" and "Australian coin", giving both status as legal tender of equal value. The Act gave the Treasurer the power to issue silver, bronze and nickel coins, with the dimensions, size, denominations, weight and fineness to be determined by proclamation of the Governor-General. The first coins were issued in 1910, produced by the Royal Mint in Lond ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bridges Completed In 1880
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, and the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge (dating from the 13th century BC, in the Peloponnese) is one of the oldest arch bridges still in existence and use. Etymology The ''Oxford English Dictionary'' traces the origin of the wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1880 Establishments In Australia
Year 188 (CLXXXVIII) was a leap year starting on Monday of the Julian calendar. At the time, it was known in the Roman Empire as the Year of the Consulship of Fuscianus and Silanus (or, less frequently, year 941 ''Ab urbe condita''). The denomination 188 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Dungog Shire
Dungog Shire is a local government area in the Hunter region of New South Wales, Australia. The Shire is situated adjacent to the Barrington Tops and consists predominantly of very rugged to hilly country which becomes less rugged from north to south. Dungog Shire was formed on 1 July 1958 through the amalgamation of Wallarobba Shire with the Municipality of Dungog. The mayor of the Dungog Shire Council is Clr. John Connors, an independent politician. Main towns/villages The major population centres within the Shire are Dungog, Gresford, Paterson, Vacy, Martins Creek and Clarence Town. It also includes three main rivers, the Paterson River and Allyn River to the west and the Williams River to the east. Demographics At the , there were people in the Dungog Shire local government area, of these 50.3 per cent were male and 49.7 per cent were female. Aboriginal and Torres Strait Islander people made up 3.2 per cent of the population, which was higher than the national ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Road Bridges In New South Wales
A road is a linear way for the conveyance of traffic that mostly has an improved surface for use by vehicles (motorized and non-motorized) and pedestrians. Unlike streets, the main function of roads is transportation. There are many types of roads, including parkways, avenues, controlled-access highways (freeways, motorways, and expressways), tollways, interstates, highways, thoroughfares, and local roads. The primary features of roads include lanes, sidewalks (pavement), roadways (carriageways), medians, shoulders, verges, bike paths (cycle paths), and shared-use paths. Definitions Historically many roads were simply recognizable routes without any formal construction or some maintenance. The Organization for Economic Co-operation and Development (OECD) defines a road as "a line of communication (travelled way) using a stabilized base other than rails or air strips open to public traffic, primarily for the use of road motor vehicles running on their own wheels", which i ...

Trusses
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 t ...

Pier (architecture)
A pier, in architecture, is an upright support for a structure or superstructure such as an arch or bridge. Sections of structural walls between openings (bays) can function as piers. External or free-standing walls may have piers at the ends or on corners. Description The simplest cross section of the pier is square, or rectangular, but other shapes are also common. In medieval architecture, massive circular supports called drum piers, cruciform (cross-shaped) piers, and compound piers are common architectural elements. Columns are a similar upright support, but stand on a round base. In buildings with a sequence of bays between piers, each opening (window or door) between two piers is considered a single bay. Bridge piers Single-span bridges have abutments at each end that support the weight of the bridge and serve as retaining walls to resist lateral movement of the earthen fill of the bridge approach. Multi-span bridges require piers to support the ends of spans betwe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cast Iron
Cast iron is a class of iron–carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its color when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and ductile cast iron has spherical graphite "nodules" which stop the crack from further progressing. Carbon (C), ranging from 1.8 to 4 wt%, and silicon (Si), 1–3 wt%, are the main alloying elements of cast iron. Iron alloys with lower carbon content are known as steel. Cast iron tends to be brittle, except for malleable cast irons. With its relatively low melting point, good fluidity, castability, excellent machinability, resistance to deformation and wear resistance, cast irons have become an engineering material with a wide range of applications and are ...

Span (architecture)
Span is the distance between two intermediate supports for a structure, e.g. a beam (structure), beam or a bridge. A span can be closed by a solid beam or by a rope. The first kind is used for bridges, the second one for power lines, overhead telecommunication lines, some type of Antenna (radio), antennas or for aerial tramways. The span is a significant factor in finding the strength and size of a beam as it determines the maximum bending moment and Deflection (engineering), deflection. The maximum bending moment M_ and deflection \delta_in the pictured beam is found using: :M_ = \frac :\delta_ = \frac = \frac where :q = Uniformly distributed load :L = Length of the beam between two supports (span) :E = Modulus of elasticity :I = Area moment of inertia Note that the maximum bending moment and deflection occur midway between the two supports. From this it follows that if the span is doubled, the maximum moment (and with it the tensile stress, stress) will quadruple, and ...
