Muncy Township, Lycoming County, Pennsylvania
Muncy Township is a township in Lycoming County, Pennsylvania, United States. The population was 1,177 at the 2020 census. It is part of the Williamsport Metropolitan Statistical Area. The unincorporated village of Pennsdale is located here. There is a Religious Society of Friends (Quaker) Meeting House in Pennsdale that was built in 1799, and is one of the oldest buildings and perhaps the oldest house of worship in the county. History Muncy Township, named for the Munsee tribe, was the first township in the county north of the West Branch Susquehanna River to be formed (predating even Lycoming County itself). It was originally formed as a part of Northumberland County on April 9, 1772. Muncy Township, as one of the seven original townships of Northumberland County, was once an immense township. It had an indefinite northern border. The southern border of the township was the West Branch Susquehanna River. The eastern boundary may have been Muncy Creek, and the western boundary ...

Howe Truss
A Howe truss is a truss bridge consisting of chords, verticals, and diagonals whose vertical members are in tension and whose diagonal members are in compression. The Howe truss was invented by William Howe in 1840, and was widely used as a bridge in the mid to late 1800s. Development The earliest bridges in North America were made of wood, which was abundant and cheaper than stone or masonry. Early wooden bridges were usually of the Towne lattice truss or Burr truss design. Some later bridges were McCallum trusses (a modification of the Burr truss). About 1840, iron rods were added to wooden bridges. The Pratt truss used wooden vertical members in compression with diagonal iron braces. The Howe truss used iron vertical posts with wooden diagonal braces. Both trusses used counter-bracing, which was becoming essential now that heavy railroad trains were using bridges. In 1830, Stephen Harriman Long received a patent for an all-wood parallel chord truss bridge. Long's bridge con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Truss Bridge
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 th ...

National Register Of Historic Places
The National Register of Historic Places (NRHP) is the United States federal government's official list of districts, sites, buildings, structures and objects deemed worthy of preservation for their historical significance or "great artistic value". A property listed in the National Register, or located within a National Register Historic District, may qualify for tax incentives derived from the total value of expenses incurred in preserving the property. The passage of the National Historic Preservation Act (NHPA) in 1966 established the National Register and the process for adding properties to it. Of the more than one and a half million properties on the National Register, 95,000 are listed individually. The remainder are contributing resources within historic districts. For most of its history, the National Register has been administered by the National Park Service (NPS), an agency within the U.S. Department of the Interior. Its goals are to help property owners and inte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Philadelphia And Reading Railroad
The Reading Company ( ) was a Philadelphia-headquartered railroad that provided passenger and commercial rail transport in eastern Pennsylvania and neighboring states that operated from 1924 until its 1976 acquisition by Conrail. Commonly called the Reading Railroad, and logotyped as Reading Lines, the Reading Company was a railroad holding company for the majority of its existence and was a single railroad during its later years. It operated service as Reading Railway System and was a successor to the Philadelphia and Reading Railway Company, founded in 1833. Until the decline in anthracite loadings in the Coal Region after World War II, it was one of the most prosperous corporations in the United States. Competition with the modern trucking industry that used the interstate highway system for short-distance transportation of goods, also known as short hauls, compounded the company's problems, forcing it into bankruptcy in 1971. Its railroad operations were merged into Conrail i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bridges Completed In 1850
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.

Historic American Engineering Record In Pennsylvania
History (derived ) is the systematic study and the documentation of the human activity. The time period of event before the invention of writing systems is considered prehistory. "History" is an umbrella term comprising past events as well as the memory, discovery, collection, organization, presentation, and interpretation of these events. Historians seek knowledge of the past using historical sources such as written documents, oral accounts, art and material artifacts, and ecological markers. History is not complete and still has debatable mysteries. History is also an academic discipline which uses narrative to describe, examine, question, and analyze past events, and investigate their patterns of cause and effect. Historians often debate which narrative best explains an event, as well as the significance of different causes and effects. Historians also debate the nature of history as an end in itself, as well as its usefulness to give perspective on the problems of the p ...
