The Collapse of the Tacoma Narrows Bridge Essay -- Bridges Engineering

The wear of the Tacoma Narrows tide over The Tacoma Narrows noseband is perhaps the most notorious failure in the universe of engineering. It collapsed on November 7, 1940 just months after its opening on July 1, 1940. It was intentional by Leon Moisseiff and at its time it was the third largest open frame pair in the universe of discourse with a center span of over half a cc long. The couple was very narrow and sleek giving it a find of grace, solely this shape made it very flexible in the wind. Nicknamed the Galloping Gertie, because of its undulating behavior, the Tacoma Narrows Bridge drew the attention of motorists seeking a cheap thrill. Drivers mat that they were operate on a roller coaster, as they would disappear from smokestack in the trough of the wave. On the last day of the bridge decks existence it gave plum exemplar that its destruction was eminent. Not only did it oscillate up and down, save move side to side in a cork screw motion. subsequently h ours of this violent motion with wind speeds reaching forty and cardinal miles per hour, the bridge collapsed. With such a catastrophic failure, many people contend wherefore such an apparently well thought out propose could generate failed so badly?(This rhetorical question clearly sets up a position of inquiry-which iniates all research.) The reason for the collapse of the Tacoma Narrows Bridge is quiet controversial, but three theories reveal the basis of an engineering explanation. (Jason then instantly asserts what he found to be a possible answer to his question.) The bridge was designed at a time when America was moving toward contour products, this include the design of bridges. The Tacoma Narrows Bridge was a sleek, graceful looking suspension bridge. fault bridges consist of many cables anchored... ... suspension bridges (pp. 13-102).

Drivers felt that they were driving on a roller coaster, as they would disappear from sight in the trough of the wave. On the last day of the bridges existence it gave fair warning that its destruction was eminent. Not only did it oscillate up and down, but twisted side to side in a cork screw motion. After hours of this violent motion with wind speeds reaching forty and fifty miles per hour, the bridge collapsed. With such a catastrophic failure, many people ask why such an apparently well thought out plan could have failed so badly?(This rhetorical question clearly sets up a position of in quiry-which iniates all research.) The reason for the collapse of the Tacoma Narrows Bridge is still controversial, but three theories reveal the basis of an engineering explanation.
