Engineering Failures In The U.S.
Engineering failures in the United States can be costly, disruptive, and deadly, with the largest incidents prompting changes to engineering practice. Examples Infrastructure Francis Scott Key bridge collapse (2024) The Francis Scott Key Bridge (informally, Key Bridge or Beltway Bridge) collapsed on March 26, 2024 at 1:28 a.m., after a container ship struck one of its Bridge pier, piers. Six members of a maintenance crew were killed. The National Transportation Safety Board, NTSB has not yet released its final report on the cause of the collapse. Hubert H. Humphrey Metrodome collapse (2010) Five times in the stadium's history, heavy snows or other weather conditions have significantly damaged the roof. At about 5 a.m. Sunday morning, the roof of Minneapolis's Hubert H. Humphrey Metrodome tore under the weight of 17 inches of snow. The Metrodome has a roof of fiberglass fabric that's inflated by the stadium's air pressure, but a weekend blizzard was the trigger to c ...

New London, Texas
New London is a city in Rusk County, Texas, Rusk County, Texas, United States. The population was 1,181 at the 2020 United States census, 2020 census. New London was originally known as just "London", but because Kimble County, Texas, Kimble County had already established a United States Post Office Department, US Post Office station named London, Texas, London, the town changed its name to "New London" in 1931. History On March 18, 1937, the New London School explosion, London School Explosion killed 270 children and 24 adults. As a result of the disaster, Texas passed laws requiring natural gas to be mixed with a malodorant to provide early warning of any leak. Other states quickly followed. Eventually, malodorant in natural gas became a legal requirement in the United States.

Torsion (mechanics)
In the field of solid mechanics, torsion is the twisting of an object due to an applied torque. Torsion could be defined as strain or angular deformation, and is measured by the angle a chosen section is rotated from its equilibrium position. The resulting stress (torsional shear stress) is expressed in either the Pascal (unit), pascal (Pa), an SI unit for newtons per square metre, or in pounds per square inch (psi) while torque is expressed in newton metres (N·m) or foot-pound force (ft·lbf). In sections perpendicular to the torque axis, the resultant shear stress in this section is perpendicular to the radius. In non-circular cross-sections, twisting is accompanied by a distortion called warping, in which transverse sections do not remain plane. For shafts of uniform cross-section unrestrained against warping, the torsion-related physical properties are expressed as: : T = \frac \tau= \frac G \varphi where: * ''T'' is the applied torque or moment of torsion in Nm. * \tau (t ...

Aeroelasticity
Aeroelasticity is the branch of physics and engineering studying the interactions between the inertial, elastic, and aerodynamic forces occurring while an elastic body is exposed to a fluid flow. The study of aeroelasticity may be broadly classified into two fields: ''static aeroelasticity'' dealing with the static or steady state response of an elastic body to a fluid flow, and ''dynamic aeroelasticity'' dealing with the body's dynamic (typically vibrational) response. Aircraft are prone to aeroelastic effects because they need to be lightweight while enduring large aerodynamic loads. Aircraft are designed to avoid the following aeroelastic problems: # divergence where the aerodynamic forces increase the twist of a wing which further increases forces; # control reversal where control activation produces an opposite aerodynamic moment that reduces, or in extreme cases reverses, the control effectiveness; and # flutter which is uncontained vibration that can lead to the destr ...

Structural Integrity And Failure
Structural integrity and failure is an aspect of engineering that deals with the ability of a structure to support a designed structural load (weight, force, etc.) without breaking and includes the study of past structural failures in order to prevent failures in future designs. Structural integrity is the ability of an item—either a structural component or a structure consisting of many components—to hold together under a load, including its own weight, without breaking or deforming excessively. It assures that the construction will perform its designed function during reasonable use, for as long as its intended life span. Items are constructed with structural integrity to prevent catastrophic failure, which can result in injuries, severe damage, death, and/or monetary losses. ''Structural failure'' refers to the loss of structural integrity, or the loss of load-carrying structural capacity in either a structural component or the structure itself. Structural failure is ...

Puget Sound
Puget Sound ( ; ) is a complex estuary, estuarine system of interconnected Marine habitat, marine waterways and basins located on the northwest coast of the U.S. state of Washington (state), Washington. As a part of the Salish Sea, the sound (geography), sound has one major and two minor connections to the Strait of Juan de Fuca, which in turn connects to the open Pacific Ocean. The major connection is Admiralty Inlet; the minor connections are Deception Pass and the Swinomish Channel. Puget Sound extends approximately from Deception Pass in the north to Olympia, Washington, Olympia in the south. Its average depth is and its maximum depth, off Jefferson Point between Indianola, Washington, Indianola and Kingston, Washington, Kingston, is . The depth of the main basin, between the southern tip of Whidbey Island and Tacoma, Washington, Tacoma, is approximately .

Strait
A strait is a water body connecting two seas or water basins. The surface water is, for the most part, at the same elevation on both sides and flows through the strait in both directions, even though the topography generally constricts the flow somewhat. In some straits there is a dominant directional current. Most commonly, the strait is a narrowing channel that lies between two land masses. Straits are loci for sediment accumulation, with sand-size deposits usually occurring on the two strait exits, forming subaqueous fans or deltas. Some straits are not navigable because, for example, they are too narrow or too shallow, or because of an unnavigable reef or archipelago. Terminology The terms '' channel'', ''pass'', or ''passage'' can be synonymous and used interchangeably with ''strait'', although each is sometimes differentiated with varying senses. In Scotland, '' firth'' or ''Kyle'' are also sometimes used as synonyms for strait. Many straits are economically impor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tacoma Narrows
The Tacoma Narrows (or the Narrows), a strait, is part of Puget Sound in the U.S. state of Washington. A navigable maritime waterway between glacial landforms, the Narrows separates the Kitsap Peninsula from the city of Tacoma. The Narrows is spanned by the twin Tacoma Narrows Bridges ( State Route 16). An earlier bridge collapsed shortly after it opened. In 1841 Charles Wilkes, during the United States Exploring Expedition, named the strait simply ''Narrows''. Its name was formally set as ''The Narrows'' by Henry Kellett during the British Admiralty The Admiralty was a Departments of the Government of the United Kingdom, department of the Government of the United Kingdom that was responsible for the command of the Royal Navy.

Suspension Bridge
A suspension bridge is a type of bridge in which the deck (bridge), deck is hung below suspension wire rope, cables on vertical suspenders. The first modern examples of this type of bridge were built in the early 1800s. Simple suspension bridges, which lack vertical suspenders, have a long history in many mountainous parts of the world. Besides the bridge type most commonly called suspension bridges, covered in this article, there are other types of suspension bridges. The type covered here has cables suspended between towers, with vertical ''suspender cables'' that transfer the Structural load#Live load, imposed loads, transient load, live and Structural load#Dead load, dead loads of the deck below, upon which traffic crosses. This arrangement allows the deck to be level or to arc upward for additional clearance. Like other suspension bridge types, this type often is constructed without the use of falsework. The suspension cables must be anchored at each end of the bridge, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
