Bridge L-158
Bridge L-158 is a disused railroad bridge over Muscoot Reservoir near Goldens Bridge, New York, United States. Built to carry New York Central Railroad traffic over Rondout Creek near Kingston, it was moved to its current location in 1904. In 1960, it was taken out of service and the tracks removed. It is the only remaining double-intersection Whipple truss railroad bridge in New York. In 1978, it was listed on the National Register of Historic Places, the only bridge entirely within Westchester County to be listed in its own right.The Bear Mountain Bridge is also listed, but it is shared with Rockland County. Some other listings, such as the Gerard Crane House, include bridges but only as contributing properties or resources. Location The bridge is located over an inlet in the reservoir approximately one half-mile (1 km) west of the Goldens Bridge station on the Metro-North Harlem Line and Interstate 684. It straddles the line between the town of Lewisboro on the east ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Contributing Property
In the law regulating historic districts in the United States, a contributing property or contributing resource is any building, object, or structure which adds to the historical integrity or architectural qualities that make the historic district significant. Government agencies, at the state, national, and local level in the United States, have differing definitions of what constitutes a contributing property but there are common characteristics. Local laws often regulate the changes that can be made to contributing structures within designated historic districts. The first local ordinances dealing with the alteration of buildings within historic districts was passed in Charleston, South Carolina in 1931. Properties within a historic district fall into one of two types of property: contributing and non-contributing. A contributing property, such as a 19th-century mansion, helps make a historic district historic, while a non-contributing property, such as a modern medical clinic ...

Flange
A flange is a protruded ridge, lip or rim (wheel), rim, either external or internal, that serves to increase shear strength, strength (as the flange of an iron beam (structure), beam such as an I-beam or a T-beam); for easy attachment/transfer of contact force with another object (as the flange on the end of a pipe (fluid conveyance), pipe, steam cylinder, etc., or on the lens mount of a camera); or for stabilizing and guiding the movements of a machine or its parts (as the inside flange of a railroad car, rail car or tram train wheel, wheel, which keep the wheels from derailment, running off the rail profile, rails). Flanges are often attached using bolts in the pattern of a bolt circle. The term "flange" is also used for a kind of tool used to form flanges. Plumbing or piping A flange can also be a plate or ring to form a rim at the end of a pipe when fastened to the pipe (for example, a closet flange). A blind flange is a plate for covering or closing the end of a pipe. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chord (truss Construction)
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 ...

Phoenix Column
The Phoenix Iron Works (1855: Phoenix Iron Company; 1949: Phoenix Iron & Steel Company; 1955: Phoenix Steel Corporation), located in Phoenixville, Pennsylvania, was a manufacturer of iron and related products during the 19th century and early 20th century. Phoenix Iron Company was a major producer of cannons for the Union Army during the American Civil War. The company also produced the Phoenix column, an advance in construction material. Company facilities are a core component of the Phoenixville Historic District, a National Register of Historic Places site that was in 2006 recognized as a historic landmark by ASM International (society), ASM International. History Founded in 1790 to produce nails and purchased in 1812 by New Jersey industrialist Robert Waln, the Phoenix Iron Company (later renamed the Phoenix Iron Works) produced pig iron, wrought iron, and other iron-related materials and end products. As the complex grew, it featured a huge blast furnace and puddling (meta ... [...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] |
Abutment
An abutment is the substructure at the ends of a bridge span or dam supporting its superstructure. Single-span bridges have abutments at each end which provide vertical and lateral support for the span, as well as acting as retaining walls to resist lateral movement of the earthen fill of the bridge approach. Multi-span bridges require piers to support ends of spans unsupported by abutments. Dam abutments are generally the sides of a valley or gorge, but may be artificial in order to support arch dams such as Kurobe Dam in Japan. The civil engineering term may also refer to the structure supporting one side of an arch, or masonry used to resist the lateral forces of a vault.Pevsner, N. (1970) ''Cornwall''; 2nd ed. Harmondsworth: Penguin; p. 245 The impost or abacus of a column in classical architecture may also serve as an abutment to an arch. The word derives from the verb "abut", meaning to "touch by means of a mutual border". Use in engineering An abutment may be us ...

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] |

Somers, New York
Somers is a town located in northern Westchester County, New York, United States. As of the 2010 census, the town had a population of 20,434. The nearby Metro-North Commuter Railroad provides service to Grand Central Terminal in Manhattan with an average commute time of 65 to 75 minutes from stations at Purdys, Goldens Bridge, Croton Falls, and Katonah. History Somers was originally inhabited by Native Americans known as Kitchawanks, part of the Wappinger tribe, an Algonquian people who called the land ''Amapaugh'', meaning "fresh water fish." This land was located in the eastern segment of an tract King William III of England granted to Stephanus Van Cortlandt of New York City in 1697. The part of Van Cortlandt Manor that ultimately became Somers and Yorktown was known as the Middle District, or Hanover. European settlement in the New Oltenia area began after Van Cortlandt's death in 1700 and the final partition of his estate in 1734. Early European settlers included tenan ...

Lewisboro, New York
Lewisboro is a town in Westchester County, New York, United States. The population was 12,411 at the 2010 census. The town is named after John Lewis, an early settler. Lewisboro is a suburb of New York City. History After purchasing land from the local natives, the first settlers established themselves around South Salem. The town was formed as "Salem" in 1747. By 1790 the town assumed its current dimensions as lands were removed for other towns. The name changed to South Salem in 1806. John Lewis, a financier, requested that the town be given his name and established a fund for the town, though he did not follow through on his promise of a railroad link. An abundance of natural open space, Dry-stone walls and elegant Colonial mansions are dominant features. Lewisboro has had two noteworthy historical characters. Sarah Bishop was the hermit of West Mountain. Apparently mistreated by British soldiers at the time of the Revolutionary War, she retreated to a solitary life in the ...
