Old Cobram-Barooga Bridge
Old Cobram-Barooga Bridge is a heritage-listed former road bridge and now footbridge over the Murray River at Barooga-Cobram Road, Barooga, New South Wales, Australia. The bridge links Barooga with Cobram, its sister town in Victoria. It was designed by Ernest de Burgh (engineer) and the New South Wales Department of Public Works and built from 1900 to 1902. It is also known as RMS Bridge No 3247. It is owned by Transport for NSW. It was added to the New South Wales State Heritage Register on 1 April 2016. History Timber truss bridges in New South Wales The development of bridge technology and design was relatively static for thousands of years, with either simple, short bridges built of timber beams across a stream or substantial stone masonry arch bridges spanning rivers. In Australia, stone (and brick) arch bridges provided the major form of bridge until the middle of the nineteenth century, after which, local engineers turned to timber truss bridges to provide the majo ...

Federation Of Australia
The Federation of Australia was the process by which the six separate British self-governing colonies of Queensland, New South Wales, Victoria, Tasmania, South Australia (which also governed what is now the Northern Territory), and Western Australia agreed to unite and form the Commonwealth of Australia, establishing a system of federalism in Australia. The colonies of Fiji and New Zealand were originally part of this process, but they decided not to join the federation. Following federation, the six colonies that united to form the Commonwealth of Australia as states kept the systems of government (and the bicameral legislatures) that they had developed as separate colonies, but they also agreed to have a federal government that was responsible for matters concerning the whole nation. When the Constitution of Australia came into force, on 1 January 1901, the colonies collectively became states of the Commonwealth of Australia. The efforts to bring about federation in th ...

Port Elliot, South Australia
Port Elliot is a town in South Australia toward the eastern end of the south coast of the Fleurieu Peninsula. It is situated on the sheltered Horseshoe Bay, a small bay off the much larger Encounter Bay. Pullen Island lies outside the mouth of the bay. At the , Port Elliot had a population of 1,754, although this section of the coast is now built up almost all the way from Goolwa to Victor Harbor. Lady Bay is a small bay at the south-western end of Horseshoe Bay, past the jetty. History Horseshoe Bay was proclaimed a port in 1851, and the settlement above the bay was named Port Elliot in 1852 after Charles Elliot, the Governor of Bermuda who was a friend of the then Governor of South Australia, Sir Henry Young. The location had been previously known as Freeman's Knob; the aboriginal name for the area may have been "Witengangool". Freemans Nob was used as a lookout post for shore-base bay whaling stations in Encounter Bay in the late 1830s. The area was also used as a plac ...

Goolwa, South Australia
Goolwa is a historic river port on the Murray River near the Murray Mouth in South Australia, and joined by a bridge to Hindmarsh Island. The name "Goolwa" means "elbow" in Ngarrindjeri, the local Aboriginal language, and the area was known as "The Elbow" to the early settlers. Goolwa is approximately 85 km south of Adelaide, and is the seat of the Alexandrina Council. It is in the state electoral district of Hammond and the federal Division of Mayo.

Victor Harbor Railway Line
The Victor Harbor railway line is a broad gauge line in South Australia. It originally branched from the Adelaide to Melbourne line at Mount Barker Junction then ran south to Victor Harbor. When the mainline was converted to standard gauge and the junction was closed, the northern end of the Victor Harbor line was curtailed at Mount Barker, from the junction. History South Australia's first railway venture was the line completed in 1854 from Goolwa, on the River Murray, to the small ocean harbour at Port Elliot. Short trains pulled by horses moved freight and passengers between the shallow-draft River Murray Paddle steamers and coastal and ocean-going vessels, bypassing the narrow, shallow mouth of the river with its unpredictable currents. However, Port Elliot was extremely hazardous; seven vessels had sunk there by 1864. The line was then extended to a safer harbour at Victor Harbor.

Stairs
Stairs are a structure designed to bridge a large vertical distance between lower and higher levels by dividing it into smaller vertical distances. This is achieved as a diagonal series of horizontal platforms called steps which enable passage to the other level by stepping from one to another step in turn. Steps are very typically rectangular. Stairs may be straight, round, or may consist of two or more straight pieces connected at angles. Types of stairs include staircases (also called stairways), ladders, and escalators. Some alternatives to stairs are elevators (also called lifts), stairlifts, inclined moving walkways, and ramps. A stairwell is a vertical shaft or opening that contains a staircase. A flight (of stairs) is an inclined part of a staircase consisting of steps (and their lateral supports if supports are separate from steps). Components and terms A ''stair'', or a ''stairstep'', is one step in a flight of stairs.R.E. Putnam and G.E. Carlson, ''Architectur ...

Latticework
__NOTOC__ Latticework is an openwork framework consisting of a criss-crossed pattern of strips of building material, typically wood or metal. The design is created by crossing the strips to form a grid or weave. Latticework may be functional – for example, to allow airflow to or through an area; structural, as a truss in a lattice girder; used to add privacy, as through a lattice screen; purely decorative; or some combination of these. Latticework in stone or wood from the classical period is also called Roman lattice or ''transenna'' (plural ''transenne''). In India, the house of a rich or noble person may be built with a ''baramdah'' or verandah surrounding every level leading to the living area. The upper floors often have balconies overlooking the street that are shielded by latticed screens carved in stone called jalis which keep the area cool and give privacy.

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 sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Span (architecture)
Span is the distance between two intermediate supports for a structure, e.g. a 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 antennas or for aerial tramway An aerial tramway, sky tram, cable car, ropeway, aerial tram, telepherique, or seilbahn is a type of aerial lift which uses one or two stationary ropes for support while a third moving rope provides propulsion. With this form of lift, the grip ...s. The span is a significant factor in finding the strength and size of a beam as it determines the maximum bending moment and 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 ...

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 f ...
