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
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
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
In 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
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
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
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.

Student’s Name Institution’s Name WHY DID TACOMA NARROW BRIDGE COLLAPSE INTRODUCTION The Tacoma Narrow Bridge is pair of twin suspension bridges that span the Tacoma strait of Puget Sound in pierce county Washington. () The bridge connects the city of Tacoma with the Kitsap Peninsula and carries state Route 16. But the paper focus on the Tacoma Narrow Bridge of the 1940 and some of the reasons that led to its collapse. The 1940 Tacoma Narrow Bridge become operational as from 1 July 1940 and
This essay will review major bridge collapses, and how they were resolved to improve the design of future bridges. The two main causes of bridge failure, wind loads and improper design or design flaws, will be discussed with examples like the Tacoma bridge collapse of 1940 and the I-35 Mississippi River bridge collapse of 2007 later on in the paper (4, 1). Although these are the two usual causes of bridge collapse there are also many other reasons for bridge failure such as, corrosion by environment

The article lists volcanoes that have erupted and when they did so. Throughout the article there are pictures of volcanoes and the corresponding text shows what is being done to monitor them. The focus of the piece is the danger to Seattle and Tacoma posed by Mt. Rainier. There is an illustration of the danger zones of Mt. Rainier when it goes off and the towns that would be destroyed by it. The next piece is a short story called “A Very Warm Mountain” which is written by Ursula K. LeGuin.
I can’t walk without my heel springing out.” Mom says, “It says they are a ten and a half.” “Well they sure don’t feel like it.” “Ok, try these.” She hands me a painfully narrow pair of black and white Pumas. 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. I suck in a breath and begin the shoe donning process. I couldn’t get them on. No matter which way I tugged or pulled,
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
The coastal plain, the sierra, and the Montana. The coastal plain is an arid, elongated stretch of land extending the entire length of the country and varying in wild from about 65 to 160 km. (about 40 to 100 mi) it is a northern extension of the Tacoma Desert of Chile. The plain has few adequate harbors. Most of the desert is so dry that only10 of the 52 rivers draining the Andean slopes to the Pacific Ocean have sufficient volume to maintain the flow across the desert and reach the coast. However
as: a big truck, love the rebel flag, and dress the right way. A big truck doesn’t necessarily mean a nice truck. Most guys around here drive old, ragged, broke down trucks. The most common truck would be an older F-150’s, a Chevy Z-71, or a Toyota Tacoma. Most trucks will also have four wheel drive, this comes in handy when you go muddin and get stuck. Many of the newer nicer trucks have bigger tires, dual exhaust, a brush guard, and a lift kit. In Monticello, you are identified by your truck. Everyone

When Ted turned four, his mother, Louise took him with her and moved to Tacoma, Washington where she married Johnnie Bundy. Ted Bundy felt nothing towards his stepfather, he was very bitter that he was forced to move across the continent from his grandfather, the only man he looked up to. Although, a psychiatrist had concluded
Personal Narrative- The Real Me I was sitting, waiting impatiently for Adam. All of a sudden, this red Toyota Tacoma flew into my driveway, screech. “Hey sweetie! Are you ready to go and eat?” he screamed out of his fire red truck. In the mean time, I was sitting there, glaring out the window, talking to myself like a harebrained would do, asking the stupidest questions, “Is he going to like my disturbed family? What is he going to think of my annoying redneck relatives? I hope he likes fish.
forty days and nights in the desert," are capable of attaining the reward of Heaven, while the weak millions, "who are weak but still love Thee... must exist for the sake of the strong." 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
The Children’s Museum of Tacoma History and Life Cycle Examination The Children’s Museum of Tacoma, founded in 1985, has been a Tacoma icon for twenty-five years. Over the subsequent ten years, the Museum experienced successes in membership, attendance and funding. During its first ten years in existence, the Children’s Museum experienced an increased attendance, finally leading to the Fire Marshall enforcing capacity limits causing patrons to form waiting lines for entrance. In 1996, the Museum
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’
