Sadliers Crossing Railway Bridge
Sadliers Crossing Railway Bridge is a heritage-listed railway bridge at over Bremer River between Tallon Street, Sadliers Crossing and Dixon Street, Wulkuraka, Queensland, Australia on the Main Line (this section is now the Ipswich and Rosewood railway line. It was added to the Queensland Heritage Register on 13 November 2008. History The Sadliers Crossing Railway Bridge, which crosses east-west over the Bremer River between Tallon Street, Sadliers Crossing and Dixon Street, Wulkuraka, is a steel truss, concrete and timber bridge designed by Chief Engineer Henry Charles Stanley. Dating from 1902, it is the second bridge to cross the Bremer River at this site. In the early 1860s the colonial Queensland Government decided to establish a railway as a means of developing the colony. It was argued that rail would reduce freight costs and save travel time for passengers considering the very poor state of Queensland roads. Priority was initially given to creating a rail li ...

Bremer River (Queensland)
The Bremer River is a river that is a tributary of the Brisbane River, located in the Scenic Rim Region, Scenic Rim and Brisbane regions of South East Queensland, Australia. The -long Bremer River drains several Scenic Rim valleys in south-east Queensland, including the Fassifern Valley, with its drainage basin, catchment area covering approximately . Most valleys within the catchment have extensive river terraces. The Bremer River system is extremely degraded. European explorers John Oxley and Allan Cunningham (botanist), Allan Cunningham visited the river in 1824 and it was first named by Oxley as Bremer's Creek presumably after Captain James Bremer, James Gordon Bremer who was in charge of , at that time performing duties in the waters of the colony of New South Wales. Course and features The Bremer rises in the hills of the Scenic Rim, passes close to the town of Rosewood, Queensland, Rosewood and winds through the city of Ipswich, Queensland, Ipswich.

Grandchester, Queensland
Grandchester is a rural town and locality in the City of Ipswich, Queensland, Australia. In the , the locality of Grandchester had a population of 444 people. Geography Grandchester is located west of the Brisbane CBD. The district historically known as Hidden Vale (or Hiddenvale) is within the locality, approx south of the town of Grandchester where Hiddenvale Road has its junction with the Grandchester Mount Mort Road (). Although unofficial, the name persists in the road name, St Anne's Hidden Vale (Anglican church), Spicers Hidden Vale (a rural resort), and the Hidden Vale Wildlife Centre (jointly operated by the resort and the University of Queensland). History Grandchester was the initial terminus of the first narrow gauge mainline railway in the world. The first track opened to traffic on 31 July 1865 from Ipswich, as the Queensland Government was keen to prove the viability of its controversial 'pony railway'. The choice of Ipswich as the starting point for the first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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 ...

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 ...

Queensland Rail
Queensland Rail (QR) is a railway operator in Queensland, Australia. Owned by the Queensland Government, it operates local and long-distance passenger services, as well as owning and maintaining approximately 6,600 kilometres of track and related infrastructure. QR was also responsible for all Queensland freight services, and from 2002 operated interstate services under the Australian Railroad Group, Interail and QR National brands. These were all spun out into a separate entity in July 2010, and later privatised as Aurizon. History Beginnings Queensland Railways was the first operator in the world to adopt narrow gauge (in this case ) for a main line, and this remains the systemwide gauge within Queensland today. The colony of Queensland separated from New South Wales in 1859, and the new government was keen to facilitate development and immigration. Improved transport to the fertile Darling Downs region situated west of Toowoomba was seen as a priority. As adequate river ...
