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 speedy construction, unfortunately the bridge was destined to fail. That failure in turn changed the way every building is constructed today as well as further man’s understanding of physics and the forces of nature. In this paper we will examine the history of the Tacoma Narrows Bridge from design to construction, the failure of the bridge, and ultimately the rebuilding project.
The bridge was constructed roughly 8 miles west of downtown Tacoma and 40 miles south of Seattle. This area of Washington is a maze of waterways and islands named the Puget Sound where the Pacific Ocean meets the mainland of Washington. The original build location is known as the Tacoma Narrows, due to the proximity of Olympic Peninsula and the mainland. The Olympic Peninsula is home to beaches, the Hoh Rain Forest, the Olympic Mountains and the Victorian Seaport. The span between shores is about a mile wide which is surprisingly the closest in all 20,000 square miles of Puget Sound, hence the name Tacoma Narrows.
The Olympic Peninsula rests in the middle of the Puget Sound in Western Washington and is home to wildlife, hunting and fishing, and a few fledgling communities in the 1930’s. State officials had been p...

... due for completion in 2008. Today 90,000 vehicles cross the Tacoma Narrows a day, in the next 5 years the Washington Toll Authority Projects the bridges to transport 120,000 vehicles a day.
The Tacoma Narrows Bridge was possibly the luckiest engineering catastrophe if there ever was one. Despite the very real danger, no human life was lost and engineers and the human race alike are better off for it.

Have you ever thought about driving over a suspension bridge held up by cables? That’s what the Mackinac Bridge is. With the building of the Mackinac Bridge there has been many positive effects that have come out of it.
Once again, it is necessary to remember that the Peace Bridge is an important link between the United States and Canada. The PBA states, "There was ten million dollars traveling over the bridge weekly in 1990, presently in 2001 there is 700 million dollars traveling over the bridge weekly. " In addition, 6,000 trucks carrying commercial goods travel over the bridge daily. By the year 2003, the Peace Bridge will reach ultimate capacity. If traffic continues to grow, the bridge will become outdated by 2004.
... Another bridge would only decrease the profits of the Ambassador Bridge. Although Matty Moroun has tried to sue the governments of Michigan and Ontario over the past decade, a permit to start construction on a new bridge was passed and announced to the public on April 15th, 2014. The new bridge is to be called the Detroit River International Crossing (DRIC) or the New International Trade Crossing (NITC). The new bridge is expected to create thousands of new jobs and continue the economic prosperity of the two countries in that region. Mark Butler, the Senior Communications Advisor for Windsor Gateway Project with Transport Canada was quoted saying, “The Windsor-Detroit corridor is Canada’s most important trade artery and the busiest commercial land border crossing in North America.” The bridge is to be 6 lanes wide and expected to be operational in 2022.
The first and most challenging problem associated with building the Mackinac Bridge arrived long before the bridge was even designed. Financing such an enormous project was no easy feat. In 1928, the idea of connecting the upper and lower peninsulas was proposed to Congress for the first time (Brown 4). At the time, the suspected bridge project was very much under government scrutiny and control. In fact, the initial boost in interest in pursuing the construction of a bridge came about due to the depression. The Public Works Administration (PWA) had been created under President Franklin D. Roosevelt’s New Deal economic plan which would fund certain construction projects with th...
Nationalities in society today have a stereotype that they are unfortunately characterized by. People assume that Asians are smart and good at martial arts, that the Irish swear too much and consume too much alcohol, that Americans are obese and lazy, and that African Americans are criminals into drugs and are in prison. These stereotypes make everyone of one nationality to be the same as individuals. There are, of course, people who fit the stereotype, which is how the stereotype came to be, but there is a large number of people who defy the stereotype of their race. The film industry helps to reiterate the stereotypes of certain races by matching the race of the actor with the character in the film for a certain effect. African Americans, specifically, in modern day films have been frequently seen to both
Throughout its nearly 60 year history, the Interstate Highway System has served the United States of America far beyond its original goals. From its original purposes of uniting the country and aiding defense to the more mundane, (but equally important)such as ferrying goods across the country, the Interstate Highway System has firmly entrenched itself as one of the greatest feats of engineering the world has ever known. Record setting bridges, tunnels, and length of pavement have all been made by the vast expanse of the IHS FACT. As Dwight D. Eisenhower, then president, stated “Together, the united forces of our communication and transportation systems are dynamic elements in the very name we bear -- United States. Without them, we would be a mere alliance of many separate parts” (http://todayinsci.com/Events/Transport/HighwayInterstate-Quotations.htm 22 Feb 1955)
Along the Pacific coast and the complex shoreline of Puget Sound, small towns and large cities dot the major thoroughfares like pearls on a string. Aberdeen, Port Angeles, Everett, Seattle, Tacoma and the state capital of Olympia surround Olympic National Park. Approximately 80 percent of Washington's population lives in the region between the Pacific shore and the Puget Sound basin. Wa...
Although this is very deep rooted, women in today’s society are making advancements, in part because of the efforts of Betty Friedan. Friedan wrote the Feminist Mystique, a book about women's roles in society in the 1950's. This book is often reviered as the most influential piece of women's rights which sparked the movement for change. In 1966, Friedan cofounded a organization called NOW, and was named the presid...
...enshoff et al. (2009), it is important to mention that films that are produced by Hollywood are first and foremost strictly business. To Asian viewers, it may be easier to detect these faulty portrayals, but whether Hollywood casts a Korean to play a Japanese role, or a Chinese to play a Korean, it is all the same because Hollywood uses what works to sell its product well.
This all iron design made the bridge a lot heavier than it was designed for, which added more stress to the truss. This fact, by itself, wouldn’t cause any alarm. However, the bridge itself, was very poorly constructed. The members of the bridge were all different sizes, and they were not connected together properly. Due to the poor construction and eleven years of use, members of the bridge had started to bend due to the stress. Despite bridge engineers inspecting the bridge for eleven years, no one noticed these faults with the bridge. However, the ultimate cause of this collapse, was so tiny, only one of the investigators, after the collapse, noticed it. A tiny air hole was left during the construction of the bridge, “and grew with repeated stress over eleven years” (Escher, 2009). This hole would develop in a crack, due to the changing temperatures and the trains crossing it for over eleven years. This would weaken the overall strength of the bridge. The cold winter air and the weight of the train would ultimately prove to be too much, and the whole bridge came crashing
Hollywood’s diversity problem is well-known; however, the extent might be surprising to most Americans. According to a 2014 report by the Center for the Study of Women in Television, Film & New Media, found that females comprised only 30% of all speaking characters among the top grossing films of 2013. (Lauzen, 2014) However, minority women faired far worse than their Caucasian counterparts. As a matter of fact, if one looks at the numbers even female characters from other world’s were as better represented in film than some minority women; the numbers are as follow for women: Caucasian (73%), African American (14%), Latina (5%), Asian and other world tied (3%). (Lauzen, 2014) If the lack of representation were not enough consider a 2009 study which found that when minority groups are portrayed on television the portrayal tends to be negative. (Alexandrin, 2009) A study by Busselle and Crandall (2009) found that the manner in which African-Americans are portrayed, often as unemployed criminals, tends to have an influence on the way the public perceives African-American’s lack of economic success. Furthermore, the news media does an equally poor job in the ways that African-American’s are presented; according to the same study while 27% of Americans were considered “poor” in 1996 the images of America’s “poor” being presented by news media was heavily Black (63%). (Busselle & Crandall, 2002) Today, this can be seen in the way that African-American victims of police brutality are depicted in the media. Even when African-Americans are murdered at the hands of police for minor and non-violent offenses (e.g. Mike Brown, Eric Gardner, and Tamir Rice) they are often portrayed as thugs, criminals, and vandals. What’s more, seve...
She argued that in order to help make ends meet in her family she had to contribute to the household income. There were points where she was making more money per week than her husband, while this allowed for them to pay the bills it also caused resentment from her husband and the two were constantly fighting, sometimes these quarrels escalated to the point of violence. Betty Friedan admitted that her husband starting beating her and it become a common occurrence for her to appear on television shows with makeup coving a black eye (Life So Far 145). This demonstrated how in some circumstances men were uncomfortable with successful career women; the workplace was still considered to be a man’s domain and women were typically subjected to lower jobs. The Statement of Purpose documents the organizations leaders awareness of the economic inequalities that women faced as they occupied the bottom of the employment scale and in addition the obstacles women faced when attempting to seek higher education (Governing Now 25). NOW rejected certain societal expectations, such has a women’s role as a housewife, because it reinforced gender traditional roles; instead the organization was not shy in stating what had to be done for an egalitarian culture demonstrating that change could and should occur. In order to ensure that progress was made NOW needed to be
The Central Artery Tunnel Project, more commonly known as the Big Dig, is said to be the largest, most complex and technologically challenging highway project in American history. It is the culmination of decades of planning and forethought and is hoped to alleviate the traffic congestion that has plagued the Boston area since the invention of the automobile. The project incorporates a major underground highway system, a revolutionary cable-stayed bridge, and a series of impressive tunnel crossings, each a considerable feat on their own, all constructed in the midst of a bustling city.
The representation of race in Hollywood cinema has been a widely discussed topic in film analysis since the medium’s inception. Historically, non-caucasian ethnicities have been underrepresented and/or misrepresented on the silver screen. It was normal for a white actor or actress to adorn themselves in black or yellowface to represent these races and further alienate them into the category of “the other”. This exclusion has been used time and time again as a tool for distinguishing not the race being alienated but those who are doing the alienation. In the following essay I aim to assess this phenomenon specifically in relation to representation of Asians in Hollywood cinema. To support my theory, I will put into conversation both Gina Marchetti’s essay, “White Knights in Hong Kong” and Anne Cheng’s essay, “Beauty and the Ideal Citizenship: Inventing Asian American in Rodgers and Hammerstein’s Flower Drum Song (1961)”. It was when asked to consider the question of national identity projected upon the bodies on screen as written about by Marchetti and Cheng that I came across my own thesis. Through their in depth analysis I was able to code an underlying theme in the historical representation of Asians in cinema. The theme in which Asian identity is derived through strategically situating them as “the other” in order to explain what it truly means to be an American.
Alice’s Adventure in Wonderland tells the story of a child named Alice who is trying to find her place in this confusing world. Children have a hard time fitting into a world that revolves around adults. Throughout Alice’s adventure in wonderland she embarks on a journey of growing up. Wonderland is a very different place than young Alice is used to. However, she begins to understand the different characters she meets along the way. Towards the end of her journey Alice’s thinking has matured and she could no longer stay in that world because of her changed mentality. Alice wakes up back in the real world more grown up than before. Overall, Alice’s story is that of a young girl transitioning from childhood into adulthood.
