Vasabron September 2006
Vasabron (Swedish: "The Vasa Bridge") is a bridge over Norrström in central Stockholm, Sweden connecting Norrmalm to Gamla stan, the old city. The bridge is, unintelligibly, named after King Gustav Vasa (1496–1560), perhaps because of the vicinity to the statue of the king in front of the House of Knights. From Vasabron a much smaller bridge, Strömsborgsbron, connects to the islet Strömsborg. Nearby bridges include Riksbron, Stallbron, Norrbro, Centralbron, and Strömbron. History By the mid-19th century Stockholm was expanding quickly and the single permanent northern connection at the time, Norrbro bridge, was becoming inadequate, which is why a new bridge to the west of it was proposed. The first attempt to build the bridge was made by the British-Swedish engineer and industrialist Samuel Owen (1774–1854). He began to work on a suspension footbridge soon after an agreement with the city was settled, but the work had to be cancelled when Owen was declared bankr ...

Samuel Owen (engineer)
Samuel Owen (12 May 1774 – 15 February 1854), was a British-Swedish engineer, inventor and industrialist. He founded a workshop in Stockholm in 1809 that produced a large number of mechanical components, and since then has been regarded as "the founder of the Swedish mechanical industry". Early and personal life Owen was born in Norton in Hales, Shropshire, England on 12 May 1774. He was married three times; first in England to Ann Spen Toft, then in Sweden in 1817 to Beata Carolina Svedell. Svedell died in 1822. Soon after, Owen married Johanna Magdalena Elisabeth (1797–1880), also called "Lisette" (likely a children's name for Elizabeth). She was born "Strindberg" and her nephew was the playwright August Strindberg. In total Owen had 17 children with his three wives. Career Owen's first visit to Sweden was in 1804 to assist with the installation of four steam engines that had been sold by the company Fenton, Murray & Wood’s in Leeds, England that Owen was employed ...

List Of Bridges In Stockholm
This is a list of some of the most notable bridges and viaducts in Stockholm, starting with those located closest to the city centre. Many more bridges and viaducts could, of course, be added, including those on the rail and motorway networks, and the many grade-separated junctions in the suburbs which are a product of postwar city planning. Historical * Sveabron (where present-day Odengatan passes over Sveavägen) * Nybro or Stora Ladugårdslandsbron (across today's Berzelii Park) * Näckströms bro (connecting Norrmalm and Blasieholmen) Additionally, during the cold winters in the 19th century, ice in the city harbour made it necessary to replace ferries by temporary pontoon bridges sometimes more than 300 m in length.

Tram
A tram (called a streetcar or trolley in North America) is a rail vehicle that travels on tramway tracks on public urban streets; some include segments on segregated right-of-way. The tramlines or networks operated as public transport are called tramways or simply trams/streetcars. Many recently built tramways use the contemporary term light rail. The vehicles are called streetcars or trolleys (not to be confused with trolleybus) in North America and trams or tramcars elsewhere. The first two terms are often used interchangeably in the United States, with ''trolley'' being the preferred term in the eastern US and ''streetcar'' in the western US. ''Streetcar'' or ''tramway'' are preferred in Canada. In parts of the United States, internally powered buses made to resemble a streetcar are often referred to as "trolleys". To avoid further confusion with trolley buses, the American Public Transportation Association (APTA) refers to them as "trolley-replica buses". In the Unit ...

Bonde Palace
The Bonde Palace ( sv, Bondeska palatset) is a palace in Gamla stan, the old town in central Stockholm, Sweden. Located between the House of Knights (''Riddarhuset'') and the Chancellery House (''Kanslihuset''), it is, arguably, the most prominent monument of the era of the Swedish Empire (1611–1718), originally designed by Nicodemus Tessin the Elder and Jean De la Vallée in 1662-1667 as the private residence of the Lord High Treasurer Gustaf Bonde (1620–1667) it still bears his name, while it accommodated the Stockholm Court House from the 18th century and since 1949 houses the Swedish Supreme Court. On the south side of the building is the street Myntgatan and the square Riddarhustorget, while the alleys Riddarhusgränd and Rådhusgränd are passing on its western and eastern sides. History The original design by Simon de la Vallée and Tessin the Younger, based on French Baroque and Renaissance prototypes, was H-shaped in plan, the planned two southern wings flanking a ...

Cast Steel
Steel casting is a specialized form of casting involving various types of steel cast to either final/net or near-net shape. Steel castings are used when iron castings cannot deliver enough strength or shock resistance.Oberg, p. 1332 Examples of items that are steel castings include: hydroelectric turbine wheels, forging presses, gears, railroad truck frames, valve bodies, pump casings, mining machinery, marine equipment, turbocharger turbines and engine cylinder blocks. Steel castings are categorized into two general groups: carbon steels and alloy steels. Steel castability Steel is more difficult to cast than iron. It has a higher melting point and greater shrinkage rate, which requires consideration during mold design. Risers should be given more capacity to draw from as the metal cools and shrinks. Attention should be paid to the thickness of mold cavities, as thinner areas will cool quicker than thicker areas, which can create internal stress points that can lead t ...

Asphalt
Asphalt, also known as bitumen (, ), is a sticky, black, highly viscous liquid or semi-solid form of petroleum. It may be found in natural deposits or may be a refined product, and is classed as a pitch. Before the 20th century, the term asphaltum was also used. Full text at Internet Archive (archive.org) The word is derived from the Ancient Greek ἄσφαλτος ''ásphaltos''. The largest natural deposit of asphalt in the world, estimated to contain 10 million tons, is the Pitch Lake located in La Brea in southwest Trinidad (Antilles island located on the northeastern coast of Venezuela), within the Siparia Regional Corporation. The primary use (70%) of asphalt is in Road surface, road construction, where it is used as the glue or binder mixed with construction aggregate, aggregate particles to create asphalt concrete. Its other main uses are for bituminous waterproofing products, including production of roofing felt and for sealing flat roofs. In material sciences an ...

Concrete
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined. Globally, the ready-mix concrete industry, the largest segment of the concrete market, is projected to exceed $600 billion in revenue by 2025. This widespread use results in a number of environmental impacts. Most notably, the production process for cement produces large volumes of greenhouse gas emissions, leading to net 8% of global emissions. Other environmental concerns include widespread illegal sand mining, impacts on the surrounding environment such as increased surface runoff or urban heat island effect, and potential public health implications from toxic ingredients. Significant research and development is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Riddarhusgränd
Riddarhusgränd (Swedish language, Swedish: "House of Knights' Alley") is an alley in Gamla stan, the old town in central Stockholm, Sweden. Stretching north from the square Riddarhustorget to the bridge Vasabron, it passes between the Swedish House of Knights (''Riddarhuset'') and the Bonde Palace forming a parallel street to Rådhusgränd. On either side of its northern end are the quays Riddarhuskajen and Kanslikajen. History While the House of Knights was built to the design of Simon de la Vallée in 1641–1674, and the Bonde Palace was originally designed as a private palace by Nicodemus Tessin the Elder and Jean De la Vallée in 1662–1667, the alley passing between them and named after the vicinity to the former, first appears in historical records in 1718 as ''Riddarhuus Gränden''. It was initially intended as the northern extension of Stora Nygatan, a street stretching north through the old town to Riddarhustorget, and in turn the result of the reconstruction of the w ...

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 ...
