Creative Writing : The Bridge Keeps Falling Up In My School

This used engineering because we had to design a scale drawing of each piece and measurement in the design. There was only little room for human error for it could have been fatal for the design. This was a much harder project than the rest and it took a substantial amount of skill to develop a good plan for the bridge. This made the students think and perform precise (as always) measurements. Lots of math was involved in the building in the bridge.

Initially, suspension bridges before 1940 were made of piers, towers, wires, anchorages, and roadways. Piers were the main foundation for the suspension bridges. There usually were two of them, which were made out of cement and were entrenched in ground underneath the body of water that the bridge was spanned across. Towers were built on top of the piers to provide a means of connection for the roadways and wires. Wires were connected to the towers, roadways, and anchorages to provide tension support for the weight of the bridge. The anchorages were large cement platforms that were planted into the ground on either side of the land so that the wires could be connected to it. Lastly, the roadways were the main point of the suspension bridge. They usually were wide enough to provide four lanes of traffic and stretched from one side of the bridge to the other. This was the basic design of the suspension bridges

We needed to fully utilise our knowledge by applying all the basic concepts in physics such as dynamic equilibrium and knowing the stiffness of the materials to build strong miniature bridge using given items to withstand the weight applied.

America has 5,540 deficient bridges alone, according to the American Society of Civil Engineers’ Infrastructure Report Card. Every four years, ASCE provides America with an assessment including recommendations, condition, and needs for the nation’s infrastructure. In a basic A-F format, the Report Card is graded in eight main categories: capacity, condition, funding, future need, operation and maintenance, public safety, resilience, and innovation. This report card, since 1998, has given the nation a steady D, only rising to a D+ in the 2013 report. The Report states that there is a need of 3.6 trillion dollars in investments by 2020 to raise the grade up to a B. Funding America’s infrastructure is of major controversy and debate. Starting

Yarden: While creating our bridge our initial plans were much different than what our final product was. The more we worried about the strength of the bridge, the less time we had. We started off with the idea to have a truss bridge made of wood and cardboard. As shown here, (show picture from journal entry), but as the project progressed our ideas continued to change.

There are many differences between our bridge and other bridges. One being location. Another one being that thing that was sacrificed for it. Another one being cost. Also another difference would be weight and capacity, and the size or length.

The cost of building a new bridge is one of the most important parts for the people there who have to pay for it and building a very expensive bridge makes a lot of people sceptic.

Before steel bridges were built, trade had to be done through the use of ships and boats, slowing down the process. However, through the use of steel bridges, “the cost of travel and trade” has decreased by an enormous amount (“Introduction: What are bridges for?). Michael G. Barker, a professor in the College of Engineering and Applied Sciences at the University of Wyoming, collaborated with an engineering consultant and conducted some research on steel bridges. He studied two bridges-- one steel, and the other concrete, which were both built in 2012 in the same location, with the same dimensions, and looked very similar. In his study, he found that “the steel . . . superstructure provided a 25.8 percent cost savings, with an overall 19.3 percent savings in the total cost of the structure” than the concrete bridge. This clearly shows that steel bridges are not very costly as other types of

In 1919, a study was begun to see if it would be possible to build a bridge across the Golden Gate. Michael O’Shaughnessy was the San Francisco city engineer. He was in charge of the rebuilding of the city after the devastating 1906 earthquake that destroyed much of the city. O’Shaughnessy knew the need for the city to have bridges. Most said it could not be done and others said it could be done but “it would cost about $100 million to build it” (Barter 23). O’Shaughnessy and Strauss, both wanting the same thing, got together. After the two consulted, they figured the only way to bridge the channel was to use a suspension bridge.

2. The only problem that we had with our instructions was that they were too long. Our joint venture partner had not tested the time it would take someone, who was seeing the instructions for the first, to build the bridge. It would have made it much easier if the instructions had given time limits. For example stating that step 2 should be finished before there is 20 minutes left.

Finally, our platoon arrived at the bridge place. Already on arrival, we realized the first problem. The road that led to the bridge was very narrow. This greatly hindered the way that we had to put our bridge material on the ground. Looking around us, we realized we had a solution. There was a private land next to the perfect installation location to accommodate all material. I shifted up to the residence with our sergeant who was a French interpreter. I knocked in her door and my partner explained the entire situation. She listened us

It was a great challenge and we got great success out of it. It has been one of the harder projects we have done. Although our bridge was incomplete by the deadline, we tested what we had built and saw that is was stronger than many of the other larger bridges that were built.

Since the bridge is a "critical piece of infrastructure" connecting drivers traveling between Arizona and California, the goal of Caltrans was to speed up the design and construction of the bridge. Caltrans selected Accelerated Bridge Construction (ABC) methods to significantly

Following the end of World War I, San Francisco city engineer Michael O’Shaughnessy began challenging engineers to design and construct a bridge across the Golden Gate. Due the location’s geography, most claimed that such a project would cost no less than

It is shaped in a way to transfer weight to the towers and anchors with its tension (O'Connor, 1971, p. 372). Cables are made of high strength wires spirally bound to form a rope (O'Connor, 1971, p. 372). Vertical cable suspenders that are fastened to the main cables hang the actual roadway. Stiffening girders and trusses are along the side of the bridge to distribute concentrated loads and help to keep the motion of the bridge at a minimum (Troitsky, 1994, p115).
