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 inclusions (up to 2% by weight), which give it a wood-like "grain" that is visible when it is etched, rusted, or bent to failure. Wrought iron is tough, malleable, ductile, corrosion resistant, and easily forge welded, but is more difficult to 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 mild steel, also called low-carbon steel. Neither wrought iron nor mild steel contain enough carbon to be hardenable by heating and quenching. Wrought iron is highly refined, with a small amount of silic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wrought Iron Bridge Company
The Wrought Iron Bridge Company was a bridge fabrication and construction company based in Canton, Ohio, United States. It specialized in the fabrication of iron truss bridges and was a prolific bridge builder in the late 19th century. It was one of the 28 firms consolidated by J. P. Morgan into the American Bridge Company in 1900. Many of its bridges have been listed on the National Register of Historic Places. Products The Wrought Iron Bridge Company specialized in relatively short-span iron truss bridges. Most were built for highway use, as the railroads were all privately owned at the time and employed their own engineers. The company supplied a catalog of bridge designs and mass-produced the parts to build these designs. Once a bridge was ordered, the pieces were shipped by train to the nearest station. Thus, local contractors were able to assemble a bridge very quickly, much like a model. 1882 pamphlet An illustrated pamphlet, dated 1882, is availablonline In this pamphl ...

Canton, Ohio
Canton () is a city in and the county seat of Stark County, Ohio. It is located approximately south of Cleveland and south of Akron in Northeast Ohio. The city lies on the edge of Ohio's extensive Amish country, particularly in Holmes and Wayne counties to the city's west and southwest. As of the 2020 Census, the population of Canton was 70,872, making Canton eighth among Ohio cities in population. It is the largest municipality in the Canton–Massillon metropolitan area, which includes all of Stark and Carroll counties, and was home to 401,574 residents in 2020. Founded in 1805 alongside the Middle and West Branches of Nimishillen Creek, Canton became a heavy manufacturing center because of its numerous railroad lines. However, its status in that regard began to decline during the late 20th century, as shifts in the manufacturing industry led to the relocation or downsizing of many factories and workers. After this decline, the city's industry diversified into ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pratt Truss
A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units. The connected elements (typically straight) may be stressed from tension, compression, or sometimes both in response to dynamic loads. The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by 19th and early 20th-century engineers. A truss bridge is economical to construct because it uses materials efficiently. Design The nature of a truss allows the analysis of its structure using a few assumptions and the application of Newton's laws of motion according to the branch of physics known as statics. For purposes of analysis, trusses are assumed to be pin jointed where the straight components meet, meaning that taken alone, every joint on the structure is functionally considered to be a flexible joint as opposed to a rigid joint with strength to maintain its own shape, and ...

Road Bridges On The National Register Of Historic Places In Maryland
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 ...

Bridges In Frederick County, Maryland
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.
