1. Introduction This memo is a failure analysis report on the Tacoma Narrows bridge. The bridge collapsed on November 7th, 1940 just over four months after it was opened to the public on July 1st, 1940(Green, 2006). The only casualties(good word??) from the bridge collapse were reporter Leonard Coatsworth’s car and dog. The bridge’s design and failure will be discussed, as well as new suspension bridge design methods. 2. Description of Failure Other similar built bridges such as the Golden Gate
The Tacoma Narrows Bridge, was also known as the Galloping Gertie, was one of the most famous cause study of structure failure in the world. The idea for constructuring of the bridge came up in the date back to 1889 with a Northern Pacific Railway proposal for a trestle. Then after a few yerars of concreted and construction with the cost of over 6,400,000 dallors, the bridge was been build and became the third longest and the most flexible suspension bridge in the world of its time of 1900s with
this failure analysis report the topic of choice that will be addressed is the engineering failure of the 1940 Tacoma Narrows Bridge in the U.S.A state of Washington that collapsed in the November 1940 due to its structural design not being aerodynamic, which caused the phenomenon called aeroelastic flutter to occur. The report will address the type of failure the 1940 Tacoma Narrow Bridge is classified under and strategies to mitigate the problem. The report will also discuss the reason for its failure

Stakeholder identification and Salience Theory article most of all. Too often our definition of stakeholder is either too broad or narrow to fit in our analysis for change. The broad definition of stake or stakeholders limits an analysts scope to the individual or group who can and are affected by the achievement of an organization (Mitchell, Agle, Wood, 1997). However, on the narrow side of the definition, a stakeholder analyst can “pigeon hole” their scope to those who are voluntary, those who have invested

I look at them, then at my mother, then back at the pair of shoes. I can almost feel the agonizing squeeze of the narrow, leather/cloth-laden shoes just by looking at them.

The Inquisitor states that the reason the weak cannot take the narrow road to Heaven is that they are afraid of freedom, that "they can never be free." Trent Reznor of the musical group Nine Inch Nails summarized the Inquisitor's view of humanity in "Happiness In Slavery." In the second verse, Reznor sings, "Slave screams
INTRODUCTION: The Tacoma Narrows Bridge was the third longest suspension span in the world at the time. It was suppose to have been revolutionary in it design, and it was known for it’s tendency to sway windstorm. Nevertheless, on November 7, 1940, a large storm caused it to collapse. WHAT HAPPENED? WHY? Even during the construction of the original Tacoma Narrow Bridge, the deck would go up and down by several feet with the slightest breeze. Construction workers on the span chewed on lemon wedges
Tacoma Narrows Bridge One of the most influential engineering discoveries in the past century was the ill-fated Tacoma Narrows Bridge. “Galloping Gertie” as she was known to local residents, the massive Washington state suspension bridge shook, rattled and rolled its way into the history books. Legendary in its time, the Tacoma Narrows Bridge held many records and drew tourists from around the world in its short life. However, the famous bridge is not known for its creative engineering or
the easy road. Just as the author of Matthew wrote, “Enter through the narrow gate. For wide is the gate and broad is the road that leads to destruction, and many enter through it. But small is the gate and narrow the road that leads to life, and only a few find it (New).” Here the author is saying that it is very easy to walk down the path that is easiest and that most walk down, but it is very difficult to find that narrow path that many choose not to take because of its difficulty. I argue that
Gilberto Torillo November 20, 2014 Art 1010-LD07 Prof. Pollak Museum Paper and Visit: Narrow Street In Paris: Out of hundreds of paintings that were on displayed in the Phillips Collection Museum, the painting that caught most of my attention was of Pierre Bonnard. Entitled “Narrow Street in Paris” he combines different elements to produce a wonderful masterpiece. Painted in the year of 1897, Pierre Bonnard created the painting using oil on cardboard set into the wood panel. The country of origin
Language, Imagery, and Diction in Emily Dickinson's Because I could not stop for Death, A narrow Fellow in the Grass, and I felt a Funeral in my Brain All good poets use the basic literary techniques of figurative language, imagery, and diction in their poems. However, only great poets use these techniques to transmit an experience to the reader; Emily Dickinson was one these poets. She used these techniques to bring the reader a new perception of life, and to widen and sharpen the readers’
thought twice after hitting the deer and had no sincerity towards nature nor the decency to at least move the carcass off the narrow road. The deer lay in the road, unburied, uncared for, unmourned, and untended. Ironically, if the carcass had remained on the road, it might have meant the taking of the life of another driver as Stafford stated in line 4: "that road is narrow; to swerve might make more dead". The tone of this poem is one of sadness, but also blata... ... middle of paper ...
oars divide the ocean....." Dickinson's attitude to passing moments is quite complex, as she does not interpret them simply as a "passing moment" but an extraordinary descriptive event. Another example of a passing moment would be in "A narrow fellow in the grass" In this poem Dickinson's keen observation of passing moments is clearly observed. She notices every movement of the snake even though his movements are very sudden and fast. Initially the snake is characterized as transient
When i was a child i wis afraid of the dark I told my mum agrain and again I heard voices in it. They weren't evil but they didn't sound familiar so they scared me. It was normal for me to wake up and hear whispers as I would call them when asking my mom. She figured they were just bumps in the night and typical kids nightmare material. I tried often to explain to her that it was more than that; that they sounded different from one another the way people’s voices do. On some nights I would get so
The Collapse of the Tacoma Narrows Bridge The Tacoma Narrows Bridge is perhaps the most notorious failure in the world of engineering. It collapsed on November 7, 1940 just months after its opening on July 1, 1940. It was designed by Leon Moisseiff and at its time it was the third largest suspension bridge in the world with a center span of over half a mile long. The bridge was very narrow and sleek giving it a look of grace, but this design made it very flexible in the wind. Nicknamed the
poem, "A Narrow Fellow in the Grass," to make the reader understand what the meaning is in the poem. In the article, "Excerpts from 'A Narrow Fellow in the Grass'," it states that "The poem is structured to relate the speaker’s experience in encountering nature, specifically in the form of a snake" (Estes 2). Thus, meaning that the author of the poem is talking about a snake in his experience. In the poem, "A Narrow Fellow in the Grass," the author states that the snake is "A narrow Fellow in
The Narrow Road to the Deep North by Richard Flanagan focuses on the life of Dorrigo Evans, an Australian prisoner of war in a Japanese internment camp during World War II. Like many other novels published after World War II, it firmly censures war. Flanagan does not spare the reader any description of the terrible circumstances of war. Unlike several other anti-war novels, however, he depicts the maladies of being a prisoner of war along with the circumstances of combat and post-war impacts. Flanagan
In the poem "Nuns fret not at their convent's narrow room" by Williams Wordsworth, he expressed in great detail the meaning of confinement. This poem is a sonnet that consists of 14 lines, and one couplet. Also, this poem is an iambic pentameter which has 10 syllables per line and five sets of unstressed syllables followed by stressed syllables. The Volta or turning point of thought in this poem is discover when Wordsworth stated "In truth the prison, into which we are doom" (Wordsworth 8). Confinement
Thesis: In order to prevent the collapse of the Tacoma Narrows Bridge, all the static and dynamic strains should have been taken into account which would have involved proper consideration of effects of environmental conditions, building materials and design.
