Philadelphia
Philadelphia, often called Philly, is the largest city in the Commonwealth of Pennsylvania, the sixth-largest city in the U.S., the second-largest city in both the Northeast megalopolis and Mid-Atlantic regions after New York City. Since 1854, the city has been coextensive with Philadelphia County, the most populous county in Pennsylvania and the urban core of the Delaware Valley, the nation's seventh-largest and one of world's largest metropolitan regions, with 6.245 million residents . The city's population at the 2020 census was 1,603,797, and over 56 million people live within of Philadelphia. Philadelphia was founded in 1682 by William Penn, an English Quaker. The city served as capital of the Pennsylvania Colony during the British colonial era and went on to play a historic and vital role as the central meeting place for the nation's founding fathers whose plans and actions in Philadelphia ultimately inspired the American Revolution and the nation's inde ...

Second Lieutenant
Second lieutenant is a junior commissioned officer military rank in many armed forces, comparable to NATO OF-1 rank. Australia The rank of second lieutenant existed in the military forces of the Australian colonies and Australian Army until 1986. In the colonial forces, which closely followed the practices of the British military, the rank of second lieutenant began to replace ranks such as ensign and cornet from 1871. New appointments to the rank of second lieutenant ceased in the regular army in 1986. Immediately prior to this change, the rank had been effectively reserved for new graduates from the Officer Cadet School, Portsea which closed in 1985. (Graduates of the Australian Defence Force Academy (ADFA) and the Royal Military College, Duntroon (RMC-D) are commissioned as lieutenants.). The rank of second lieutenant is only appointed to officers in special appointments such as training institutions, university regiments and while under probation during training. Trai ...

Engineering
Engineering is the use of scientific method, scientific principles to design and build machines, structures, and other items, including bridges, tunnels, roads, vehicles, and buildings. The discipline of engineering encompasses a broad range of more specialized List of engineering branches, fields of engineering, each with a more specific emphasis on particular areas of applied mathematics, applied science, and types of application. See glossary of engineering. The term ''engineering'' is derived from the Latin ''ingenium'', meaning "cleverness" and ''ingeniare'', meaning "to contrive, devise". Definition The American Engineers' Council for Professional Development (ECPD, the predecessor of Accreditation Board for Engineering and Technology, ABET) has defined "engineering" as: The creative application of scientific principles to design or develop structures, machines, apparatus, or manufacturing processes, or works utilizing them singly or in combination; or to construct o ...

Mathematics
Mathematics is an area of knowledge that includes the topics of numbers, formulas and related structures, shapes and the spaces in which they are contained, and quantities and their changes. These topics are represented in modern mathematics with the major subdisciplines of number theory, algebra, geometry, and analysis, respectively. There is no general consensus among mathematicians about a common definition for their academic discipline. Most mathematical activity involves the discovery of properties of abstract objects and the use of pure reason to prove them. These objects consist of either abstractions from nature orin modern mathematicsentities that are stipulated to have certain properties, called axioms. A ''proof'' consists of a succession of applications of deductive rules to already established results. These results include previously proved theorems, axioms, andin case of abstraction from naturesome basic properties that are considered true starting points of ...

Professor
Professor (commonly abbreviated as Prof.) is an Academy, academic rank at university, universities and other post-secondary education and research institutions in most countries. Literally, ''professor'' derives from Latin as a "person who professes". Professors are usually experts in their field and teachers of the highest rank. In most systems of List of academic ranks, academic ranks, "professor" as an unqualified title refers only to the most senior academic position, sometimes informally known as "full professor". In some countries and institutions, the word "professor" is also used in titles of lower ranks such as associate professor and assistant professor; this is particularly the case in the United States, where the unqualified word is also used colloquially to refer to associate and assistant professors as well. This usage would be considered incorrect among other academic communities. However, the otherwise unqualified title "Professor" designated with a capital let ...

Ardmore, Pennsylvania
Ardmore is an unincorporated community and census-designated place (CDP) spanning the border between Delaware and Montgomery counties in the U.S. state of Pennsylvania. The population was 12,455 at the 2010 census and had risen to 13,566 in the 2020 census. Ardmore is a suburb on the west side of Philadelphia within Lower Merion Township in Montgomery County and Haverford Township in Delaware County. Originally named "Athensville" in 1853, the community and its railroad station were renamed Ardmore in 1873 by the Pennsylvania Railroad, on whose Main Line, west out of Philadelphia, Ardmore sits at Milepost 8.5. The Autocar Company moved its headquarters to Ardmore in 1899 and constructed a factory on the edge of the downtown area. The factory closed in 1954; during demolition in 1956, a major fire broke out that threatened the downtown area before it was extinguished. Today, Ardmore consistently ranks among the most desirable suburbs of Philadelphia. Geography According to the ... [...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 ...

South Mountain (Maryland And Pennsylvania)
South Mountain is the northern extension of the Blue Ridge Mountain range in Maryland and Pennsylvania. From the Potomac River near Knoxville, Maryland in the south to Dillsburg, Pennsylvania in York County, Pennsylvania in the north, the range separates the Hagerstown and Cumberland valleys from the Piedmont regions of the two states. The Appalachian National Scenic Trail follows the crest of the mountain through Maryland and a portion of Pennsylvania. Geography South Mountain begins at the Potomac River as a low, narrow ridge, barely one mile wide and only above sea level at its crest. South of the Potomac River in Virginia, the ridge continues as Short Hill Mountain for about before subsiding near the town of Hillsboro. South Mountain in Maryland gradually grows higher and wider towards the north. Near the Pennsylvania border, the mountain merges with the hills of the parallel Catoctin Mountain range to the east and becomes more like a low mountain range than a single cre ...
