George S. Morison
George Shattuck Morison (December 19, 1842 – July 1, 1903) was an American attorney best known as a designer of bridges. He was trained to be a lawyer but instead became a civil engineer and leading bridge designer in North America in the late 19th century. During his lifetime, bridge design evolved from using 'empirical “rules of thumb” to the use of mathematical analysis techniques'.Marianos Jr, W. N. "George Shattuck Morison and the development of bridge engineering." American Society of Civil Engineers (ASCE) Journal of Bridge Engineering 13.3 (2008): 291-298. Accessed a/ref> Some of Morison's projects included several large Missouri River bridges as well as the Frisco Bridge, great cantilever railroad bridge at Memphis, Tennessee, and the Boone, Iowa viaduct. Morison served as President of the American Society of Civil Engineers (1895) as well as a member of the British Institute of Civil Engineers winning that institution's Telford Medal in 1892 for his work on the Mem ...

New Bedford, Massachusetts
New Bedford (Massachusett language, Massachusett: ) is a city in Bristol County, Massachusetts, Bristol County, Massachusetts. It is located on the Acushnet River in what is known as the South Coast (Massachusetts), South Coast region. Up through the 17th century, the area was the territory of the Wampanoag Native American people. English colonists bought the land on which New Bedford would later be built from the Wampanoag in 1652, and the original colonial settlement that would later become the city was founded by English Quakers in the late 17th century. The town of New Bedford itself was officially incorporated in 1787. During the first half of the 19th century, New Bedford was one of the world's most important whaling ports. At its economic height during this period, New Bedford was the wealthiest city in the world per capita. New Bedford was also a Abolitionism in New Bedford, Massachusetts, center of abolitionism at this time. The city attracted many freed or escaped Afric ...

Isthmus Canal Commission
The Isthmian Canal Commission (often known as the ICC) was an American administration commission set up to oversee the construction of the Panama Canal in the early years of American involvement. Established on February 26, 1904, it was given control of the Panama Canal Zone over which the United States exercised sovereignty. The commission reported directly to Secretary of War William Taft. It was initially composed of seven members, appointed by President Theodore Roosevelt, directed to avoid the inefficiency and corruption that had plagued the French 15 years earlier. On May 6, 1904, President Theodore Roosevelt appointed John Findley Wallace, formerly chief engineer and finally general manager of the Illinois Central Railroad, chief engineer of the Panama Canal project. Wallace was paid a $25,000 annual salary, the highest of any government employee at that time other than the president. In addition to the engineering and health problems, Wallace faced many bureaucratic challen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lower Mississippi River
The Lower Mississippi River is the portion of the Mississippi River downstream of Cairo, Illinois. From the confluence of the Ohio River and Upper Mississippi River at Cairo, the Lower flows just under 1000 miles (1600 km) to the Gulf of Mexico. It is the most heavily travelled component of the Mississippi River System. Structures Unlike on the upper rivers, there are no locks or dams on the Lower Mississippi. The river is, however, constrained by levees and dikes to control flooding and secure a navigation channel for barges. The Old River Control Structure, the Bonnet Carré Spillway, the Mississippi River – Gulf Outlet Canal and other man-made structures on the lower reaches of the river seek to manipulate the flow of water in the vicinity of New Orleans. History The political and engineering focus in the 20th century was to separate the Lower Mississippi River from its floodplain. Levees and channelization—along with substantial loss of bottomland fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mississippi River
The Mississippi River is the second-longest river and chief river of the second-largest drainage system in North America, second only to the Hudson Bay drainage system. From its traditional source of Lake Itasca in northern Minnesota, it flows generally south for to the Mississippi River Delta in the Gulf of Mexico. With its many tributaries, the Mississippi's watershed drains all or parts of 32 U.S. states and two Canadian provinces between the Rocky and Appalachian mountains. The main stem is entirely within the United States; the total drainage basin is , of which only about one percent is in Canada. The Mississippi ranks as the thirteenth-largest river by discharge in the world. The river either borders or passes through the states of Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana. Native Americans have lived along the Mississippi River and its tributaries for thousands of years. Most were hunter-ga ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ohio River
The Ohio River is a long river in the United States. It is located at the boundary of the Midwestern and Southern United States, flowing southwesterly from western Pennsylvania to its mouth on the Mississippi River at the southern tip of Illinois. It is the third largest river by discharge volume in the United States and the largest tributary by volume of the north-south flowing Mississippi River that divides the eastern from western United States. It is also the 6th oldest river on the North American continent. The river flows through or along the border of six states, and its drainage basin includes parts of 14 states. Through its largest tributary, the Tennessee River, the basin includes several states of the southeastern U.S. It is the source of drinking water for five million people. The lower Ohio River just below Louisville is obstructed by rapids known as the Falls of the Ohio where the elevation falls in restricting larger commercial navigation, although in the 18th ...

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 ...

Steel
Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, weapons, and rockets. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile, or soft and easily formed. In steel, small amounts of carbon, other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joseph Tomlinson III
Joseph Tomlinson III (June 22, 1816 – May 10, 1905) was an English American engineer and architect who built bridges and lighthouses in Canada and the United States. In 1868, he co-designed and oversaw the construction of the Hannibal Bridge, the first permanent crossing of the Missouri River. He was the first person to hold the position of General Superintendent of Lighthouses for the new Dominion of Canada, holding that position beginning in January 1870. For eight years, he worked building railroad bridges for the Canadian government, and designed one of the most impressive bridges on the Canadian Pacific Railway where it crossed the Fraser River. He designed a railroad bridge over the Ashtabula River in Ohio, but was fired from the project after he refused to make supervisor-ordered changes to the design which he considered unsafe. The bridge failed on December 29, 1876, killing 92 people in a train derailment. Early life and education Tomlinson was born June 22, 1816, in ...

Mechanics
Mechanics (from Ancient Greek: μηχανική, ''mēkhanikḗ'', "of machines") is the area of mathematics and physics concerned with the relationships between force, matter, and motion among physical objects. Forces applied to objects result in displacements, or changes of an object's position relative to its environment. Theoretical expositions of this branch of physics has its origins in Ancient Greece, for instance, in the writings of Aristotle and Archimedes (see History of classical mechanics and Timeline of classical mechanics). During the early modern period, scientists such as Galileo, Kepler, Huygens, and Newton laid the foundation for what is now known as classical mechanics. As a branch of classical physics, mechanics deals with bodies that are either at rest or are moving with velocities significantly less than the speed of light. It can also be defined as the physical science that deals with the motion of and forces on bodies not in the quantum realm ...
