Bridge Truss

...simple bridge truss was the first structure I ever analyzed. The simple combination of beams that could hold cars, trains, and trucks over long spans of water fascinated me. Having the tools to analyze the loads on the truss further increased my interest in structures. I encountered the bridge in a textbook for my first engineering class. Knowing that the professor, Mr. John Doe, was a tough teacher, I asked him for the textbook so I could study and get ready for the class over the summer. Just arrived from Belize, I was determined to succeed. In class we learned about forces on simple members and then we put the members together to form a simple truss. At this point I had almost decided that structural engineering was the career for me. From there the class just took off: We went on to frames, distributed loads, considered friction; basically we were incorporating real world considerations into structural members. I loved the practical, problem solving aspects of the field. At UC my classes were even more advanced. In my analysis and design classes, I especially enjoyed studying steel design because we not only learned the use of the load resistance factor design but also applied that knowledge — I designed a four-story building. The professor was a practicing engineer, and he always related the subject to real life steel structures he had engineered, for example, the SB Medical Center, an all steel building with a base isolated campus. This is the kind of project on...

Creative Bridge Creation Story

...It was now January 31st, and Sydni Kellie and Lauren hadn’t even begun to start their bridge yet. They always talked about beginning it but never followed through. Something had always come up- dance, soccer, horses. They used pictures of other peoples bridges for t when Mr. Buck checked their progress. But it had gotten to the point where they had reached desperation. It was the last minute, and all they had was a bucket filled with supplies. It was eight in the morning and Sydni and Kellie were sitting in Kellie’s car. They had 24 hours to build a bridge adequate enough to pass. Lauren suddenly banged on the car, and there was a piece of paper with writing on it. Sydni rolled down her window, and snatched the paper from Laurens grasp. “What is this?” “Good morning to you too syd.” “ya, hi. Whos number is this ?” “A tutor! His name is Andrew.“ “Ok? Thanks for the insult Lauren,but I think I can handle passing Physics by myself..,” “No syd. That’s not what she means. Lauren are you saying that this guy can build us a bridge?…” “Yes kellie! That’s exactly what Im saying!” The three girls stared at each other in silence, and then all began talking at once. “Let’s call hi..” “Should we cal..” “Is this illeg…” Eventually, one of them ended up dialing the number. After the third ring, a man answered, “Andrew’s castle, whats your hastle?” “uhhhh. Sorry to bother you Andrew, my name is sydni. me and my friends need a little favor.” After 5 minutes, Sydni......

Alenxander's Bridge

...Alexander rose quickly. "There he is. Away with perspective! No past, no future for Bartley; just the fiery moment. The only moment that ever was or will be in the world!" The door from the hall opened, a voice called "Winifred?" hurriedly, and a big man came through the drawing-room with a quick, heavy tread, bringing with him a smell of cigar smoke and chill out-of-doors air. When Alexander reached the library door, he switched on the lights and stood six feet and more in the archway, glowing with strength and cordiality and rugged, blond good looks. There were other bridge-builders in the world, certainly, but it was always Alexander's picture that the Sunday Supplement men wanted, because he looked as a tamer of rivers ought to look. Under his tumbled sandy hair his head seemed as hard and powerful as a catapult, and his shoulders looked strong enough in themselves to support a span of any one of his ten great bridges that cut the air above as many rivers. After dinner Alexander took Wilson up to his study. It was a large room over the library, and looked out upon the black river and the row of white lights along the Cambridge Embankment. The room was not at all what one might expect of an engineer's study. Wilson felt at once the harmony of beautiful things that have lived long together without obtrusions of ugliness or change. It was none of Alexander's doing, of course; those warm consonances of color had been blending and mellowing before he was born. But the......

Bridge on the Drina Review

...The Bridge on the Drina By: Ivo Andric See how Mehmed Pasha, the greatest among the wise and great of his time, Mindful of the testament of his heart, by his care and toil Has built a bridge over the River Drina, Over this water, deep and swift-flowing. His predecessors had not been able to put up anything. I pray that by the Mercy of Allah this bridge will be firm And that its existence will be passed in happiness And that it will never know sorrow. For in his lifetime he poured out gold and silver for his bequest And no man can say that fortune has been wasted Which has been spent to such an end. Badi, who has seen this, when the bridge was completed gave this tarah. “May Allah bless this building, this wonderful and beautiful bridge.” (68) Published in 1945, the novel, The Bridge on the Drina, is a moving, semi-fictional account of a bridge over the river Drina in Bosnia. Set in the small village/town of Višegrad, the novel spans from the late sixteenth century to the beginning of the First World War. Written in anecdotal style, The Bridge on the Drina relates the suffering of various peoples in relation to the bridge. The extended metaphor of a decaying bridge, paralleled with a decaying Ottoman Empire is an extremely intriguing one, one that captures and retains the reader’s attention. At the book’s conclusion, the bridge is destroyed by the Austrians, who blow an enormous hole in the center of it at the beginning of World War I; much like the......

Spaghetti Bridge

...|Spaghetti Bridge | Abstract For this assignment our task was to build as a group a spaghetti bridge with the objective of carrying the most weight as possible using only spaghetti and hot glue, meeting the specifications. The bridges will be loaded until they fall. After testing to destruction, the bridges loading capacity was 14.4kg, with an initial mas of 0.840kg. This gave a weight to strength ratio of 17.1 putting the group at 4th/8th position in class. From this it was learned the bridge held 14.4kg which is 140N therefore one Truss held 70N. These calculations helped us understand how our bridge coped with the forces and helped us answer the question of what caused our bridge to fail and where our bridge failed?

After reading this research document, the readers can understand more about what the purposes of each part are, and how each part of the suspension bridge works together. In this research document, the intended audiences or readers are the Civil Engineering students. Through this research, Civil Engineering students can receive more additional knowledge and information that are important in their selected area. This research is important to Civil Engineering students, because in the future when they graduate and become a license Engineer, they will work on infrastructures including bridges. To create a safe and well-constructed bridge, Engineers shall know what are its parts and how the bridge works. Introduction to Process Suspension bridge is a type of bridge that can be defined already from the name itself, it suspends or debars the roadway through the cables or metal chains from tall towers. These towers bear or hold almost all the weight as pressure presses down on the deck of the suspension bridge, and the pressure goes up to the cables to transfer pressure to the towers. The towers also are connected to the piers that allow the pressure to flow to the ground. Bridge has two types of parts. First is the superstructure; it talks about the upper part of the bridge it includes the deck, towers, and the......

The Brooklyn Bridge.

...The BB was the first bridge of its kind ever to be built in the early 19th century. It has braved many elements and has stood the test of time and humanity. It is the first suspension bridge to use galvanized steel as cable wires and trusses. The suspension system was originally designed in iron, but later replaced due to irons dead load weight. The four cables are each nearly 16 inches in diameter and each contains over 5,000 galvanized steel, oil-coated wires. Also the first a dangerous underwater device called Caisson (Inside the caissons, air pressure was used to keep water out of the boxed structure used by workers to excavate the river bottom. Men used shovels, picks, and later blasting to dig out the sand and rocks below and the caissons gradually descended towards the river bottom). After they had been lowered 20 meters, they had to dig/blast their way another 30 meters to find a base strong enough to carry the weight of the bridge. Granite stones were added to form the towers were 276.5ft. At one point they were taller then all skyscrapers of that time to stand as a monument of the two cities. The diagonal cables that run down from the towers which are called “cable stays” purpose was to stiffen the bridge was later fund unnecessary but they were kept for its architectural beauty contribution. "To guard against vertical and horizontal oscillations and to ensure that degree of stiffness in the flooring which is absolutely necessary to meet the effects of violent...

...BRIDGES A bridge is a structure providing passage over an obstacle without closing the way beneath. The required passage may be for a road, a railway, pedestrians, a canal or a pipeline. The obstacle to be crossed may by a river, a road, railway or a valley. History The first bridges were made by nature itself—as simple as a log fallen across a stream or stones in a river. The first bridges made by humans were probably spans of cut wooden logs or planks and eventually stones, using a simple support and crossbeam arrangement. Some early Americans used trees or bamboo poles to cross small caverns or wells to get from one place to another. A common form of lashing sticks, logs, and deciduous branches together involved the use of long reeds or other harvested fibers woven together to form a connective rope capable of binding and holding together the materials used in early bridges. Dating to the Greek Bronze Age (13th century BC), it is one of the oldest arch bridges still in existence and use. Several intact arched stone bridges from the Hellenistic era can be found in the Peloponnese in southern Greece. The greatest bridge builders of antiquity were the ancient Romans. The Romans built arch bridges and aqueducts that could stand in conditions that would damage or destroy earlier designs. Some stand today. An example is the Alcantara Bridge, built over the river Tagus, in Spain. The Romans also used cement, which reduced the variation of strength found in natural......

One way of ensuring economic fairness between states is to create infrastructure, which allows equal trading, and access. Physical linkage between all states increases the sense of community within the country. Tasmania has a lot to offer, but is disadvantaged by the lack of communication alternatives. For everyday people to reach the island one has to take either an airplane or a ferry, which means one is always dependent on the time table of these vessels. For logistics companies there is no other alternative than using air or sea......

The River as Bridge

...The River as Bridge Rivers have potential resource use and can be used to develop land. The increasing expression of human activity and climate variability on humid, terrestrial hydrologic systems has made the integrated nature of large river basins more apparent. This increased expression results in river bridging. Rivers bridge water and land together, such as oceans and mountains. They mediate between aquatic and terrestrial ecosystems which provide a natural habitat for both land and water species. Rivers do this by shaping the lay of the land through erosion, flooding, and meandering. Complex landscapes with fertile floodplains are formed because rivers carry and deposit sediments. Rivers also bridge the environment and culture. Human culture has become one of the determining factors that account for the high variability of the quality and quantity of water at any specific time and place. Humans have shaped rivers for irrigation, navigation, and flood protection. Ancient cultures and societies used river systems to construct elaborate irrigation and flood-control projects that enabled the emergence of cities and civilizations. Rivers travel long distances which help them connect a wide diversity of people and places. This makes them environmentally and culturally rich. Rivers represent the capacity for transformation in many cultures. Rivers and floodplains provide a wide range of ecosystem services. The importance of rivers and streams for freshwater, food, and......

Troll Bridge

...Written assignment: Troll Bridge We live in a society filled with norms, solid framework and expectations. We are expected not to fart at meetings or to tell every stranger we meet about our sexual preferences. Although it may seem that these “appropriate” behaviors are a pure reflection of our true selves it is not, according to psychoanalytic Sigmund Freud and Carl Jung. All humans have deeply stored inside their brains a subconscious mind, which is where all our truly desires are suppressed. These desires can be expressed differently. To take an example: Writers are often able to access a collective unconscious and use it to create artistic literary work filled with symbolism and features which are interesting to the psychoanalytic critic. One of those writers is Neil Gaiman and in his short story Troll Bridge many psychoanalytical symbols can be interpreted. The story follows the protagonist and first-person narrator Jack and his life development. Every time Jack is in a changing period of his life he meets a troll, who says he wants to eat him. First time they meet, Jack is a 7-year-old boy who is out to explore the countryside. His surroundings change as he goes and he gives a detailed picture of what his curious eyes see. When he sees a bridge he is surprised that there is any token of the existence of humanity, so he must be quite far out. It’s under this bridge Jack meets the troll who completely untraditionally introduces himself with “I am a troll” (p. 3, l.......

...Bridge Bridges was made for crossing over a large body of water or land. The design of the bridge and its function are made based on the need of the situation. Early bridges are made from natural materials like “wooden logs, stone, and dirt.” Some said that the first bridge was made from nature, when a the log fell across a stream. Bridges made from natural resources tend to disintegrated over time. The Ancient Rome, then tried to improve the bridge by using volcanic rocks to make mortar. The new resource help the bridge to withstand against mother nature and helped the Romans to make more fancy bridges. The bridges they built are more powerful, sturdy, and larger than any bridges before. The idea then spread across Europe to Asia and Africa. The design of the bridge across the world has varied from place to place. Due to circumstances and situation that the place needed. Like the moveable bridge that is designed to move to allow passage for boat or barges. Some bridge are built for fun like the bridge to nowhere in Avignon, France. The Pont d'Avignon is a medieval bridge that was destroyed by a flood later built again in the 17th century to nowhere. Other bridge-like arch bridge Sydney Harbour Bridge in Sydney, Australia, which got it weight support at both ends, the side arch is supported by tension rods, chains or cables. Hope It Works Inc. will make an arch like bridge, using mainly wood glue and toothpicks. Sandpaper, wax paper, regular paper, rubber band, ruler,...

Troll Bridge

...Setting and Narrator in Neil Gaiman’s “Troll Bridge” “Three Billy Goats Gruff” has been Neil Gaiman’s inspiration for this short story “Troll Bridge”. However, many elements from the old fairytale has been replaced and Gaiman brings a more twisted and dark version on the table. The main character, Jack, meets a troll three times and, de-spite his selfishness, actually lets the troll eat him the last time. The ending of the story is unex-pected and provides no resolution but is a crucial part to Jack’s development. The story is split up in three parts where Jack is at three different stages in his life. Throughout the whole story, the narrator uses the setting to reflect Jack’s feelings and changes through these three stages. It is a first person narrator and Jack is telling the story. In the first part of the story, the narrator is describing the setting positively and magical. Jack is 7 years old in this part and is very detailed with his description of nature and his fantasies, for example: “The light that penetrated the leaves was stained green and gold, and I thought I was in fairyland” (p. 60 l. 24-25). This makes the at-mosphere of the setting lively and Jack’s pureness as a child is present through what the narrator describes of the setting. In the next stage of his life, Jack is 15 and the atmosphere of the setting changes. The narrator starts the part with telling the reader about how the fields in the area started to go as new houses and roads took over –...

Bridges of Chicago

...have changed.” Among all these extravagant developments comes the marvel of the bridge. It's safe to say that even centuries ago, the early humans must have created bridges from the simple material they found surrounding them in their all natural environment. Whether it was a 3 by 10 foot log they had so carefully placed across the water way, or piles of smaller wood, closely intertwined and lined by the strongest of branches, the primal people had found a way to gather and hunt across streams and rivers. As the years and population had increased, so had the development and appearance of the bridge. Because of great urbanization and city growth, there was a high demand for a solution to travel in a quicker and more efficient way. One of the cities that rapidly boomed was Chicago, now the third most populous city in the United States. This growth mostly had to do with the rail road and the Chicago River. Because Chicago was fortunate enough to have a natural waterway entwined in the city, it was essential to begin the building of bridges throughout. As architects and engineers from all over gathered to create bridges both beautiful and useful, the city of Chicago continued to grow. Although used by millions of people each year, most Chicago natives and tourist fail to see the true importance of the bridges in this beautiful city. Overlooked is the importance of the many architectural designs and bridge types located in this city, the changes that took place in......
