Bridges are used by many people for many different reasons. One of the most iconic bridges is the George Washington Bridge. I wondered to myself, “ What goes into making bridges like that? “In Technology Education, I was lucky enough to be able to make a small model of the bridge through the process known as the Engineering Design Process. Although the process for making the George Washington Bridge is more complex, I saw the things that had to be incorporated to make a bridge. In Technology Education, we had to find a way to hold a 300 to 1 ratio on the bridge. In order to make a bridge that could hold that much force, I had to decide which type of bridge to make. By making my bridge on the Westpoint Bridge Designer, I decided to make a four span two leveled modified truss. When I saw how a truck went over this bridge I was confident because I barely saw any compression or tension. Now, I had to decide how to make my virtual bridge into reality with craft sticks. …show more content…
This is because the base is going to be the foundation of everything. So, I got 8 craft sticks, four for the left and four for the right. Then I got the eight sticks and went to the drill press. There, I would put holes into the craft sticks in order to put in four 3 ¾ inch dowels. After, the base was built, I glued the pieces together until the tacky glue dried. Then, I had to start making the first level of my bridge. This level consisted of four equilateral triangles. After making the triangles and inserting it into the dowel, I glued them together. Lastly, I had to make the second level of my bridge, which consisted of three squares that had X’s going through them. However, I realized that my bridge was somewhat tilting over. So, I decided to connect two craft sticks to the bottom and top of each side of the bridge, which cause the bridge to stand somewhat
Steven Hermosillo Professor Wallace Fire Tech 105 15 November 2015 Silver Bridge Collapse According to Wikipedia, Forty-six people were killed in the silver-bridge collapse and another nine people were injured. “The Silver Bridge was an eye-bar-chain suspension bridge built in 1928 and named for the color of its aluminum paint. The bridge connected Point Pleasant, West Virginia, and Gallipolis, Ohio, over the Ohio River” (Wikipedia). This was a highly used bridge serving thousands of cars a day before the collapse.
Based on the research conducted, the bridge being built will be a Pratt or Parker Bridge with a height of about 2.5 inches. Members will connect to one another through lap joints, and when a lap joint cannot be used, an end joint with two gussets securing it in place will be used. Gorilla Glue and Alteco ST50 Super Glue will be used to connect members at these joints. The glue will be applied to balsa members pinned to a workspace through a glue applicator to assist in applying a precise amount of
The Bailey Island Bridge is located in Harpswell, Maine on Route 24. Before the making of the bridge, the fishermen that lived on Bailey’s Island wanted a bridge that connected their island to Orr’s Island. The town of Harpsweell made and voted on their decisions in the weekly town meetings (“Bailey”). The project was stalled because of some of the mainlanders in the town, but it was brought back up for discussion in 1912. They first agreed on a “road” which would connect the two islands and would be constructed with timber. This was to cost $3,000. The cost quickly reached $25,000 at a later town meting because they decided to build the bridge with stone and concrete instead. Once the legislature decided to pass a bill stating that it would fun state’s highway and bridge projects, they decided to move forward with the project (Hansen, 36).
During the American Revolution, Washington and his men were experiencing a series of defeat. In order to bring about great pride and patriotism of an American, they sought to plan a sneak attack on the opposite force. On December 25, Washington and 5,400 troops began crossing the Delaware River to the Hessian stronghold. At this point in time, the Hessians were celebrating Christmas; this was a perfect time for an attack. When Washington and his men arrived, they started attacking the unsuspected Hessians; nearly 1,000 Hessians were captured. Even though the attack was not significant, it raised American spirit. In 1851, Emanuel Leutze created the image of Washington Crossing the Delaware; the painting was later destroyed, but restored by another artist. The mood of the painting can be described as intense and patriotic. Later, a poem called “Washington Crossing the Delaware” was written by David Shulman. The mood of the poem
The Golden Gate bridge, standing as an icon of roadway innovations, took multiple engineers years to design and complete. They could not just simply build an ordinary bridge. They had to take into consideration the physics behind it, as well as, what kind of effect the environment would have upon the bridge. The bridge sits along one of the most active fault lines in the world, so engineers had to make sure their bridge could withstand a little movement. Today the Golden Gate bridge still stands tried and true, as does many other innovations that 20th century engineers came up with.
During the late 1700s there was a lot of different viewpoints on how the government should be run today. The leaders of the divide were George Washington and Alexander Hamilton, which later on we will learn each one of their views. In today’s political world we would divide Washington and Hamilton views into political parties, which in the late 1700s they were called Federalists and Republicans. However, later on we see a group trying to create a democracy, which then it was called Jacksonian populism and power.
Compare with other types of bridges, suspension bridge can span the longest distance without using lots of material. However, if the issue of stiffness was not fully cosidered, vibration would be occurred on the bridge deck under high wind. A few week after the Tacoma Narrow Bridge was operated, the bridge start oscillation and its oscillation kept increasing day by day. Therefore engineers tried to build more cable between the bridge, but it is still unsuccessful. After four months the Tacoma Narrows Bridge was build, the bridgre which normally vibrated in a vertiacal motion, began to oscillate with the opposite side out of phase (torsional model), under the wind of 68 km/h. Due to the extremely violent oscillation, the failure bagan at the mid-...
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.
How important are Miller's language choices and use of stage directions in aiming the audience to view Eddie as a tragic hero in the play ‘A View from the Bridge’?
George Washington was our nation’s first president and a well respected leader, but what gave him this reputation? In David McCullough’s 1776, Washington’s leadership skills that brought the colonies to victory can be easily seen. As British and American politicians struggled to reach a compromise, events on the ground escalated until war was inevitable. McCullough recreates scenes of heroic battles as well as dramatic encounters between diplomats with outstanding details in his writing.
“The executive Power shall be vested in a President of the United States of America… No Person except a natural born Citizen, or a Citizen of the United States, at the time of the Adoption of this Constitution, shall be eligible to the Office of President; neither shall any Person be eligible to that Office who shall not have attained to the Age of thirty-five Years, and been fourteen Years a Resident within the United States” (“The Constitution” National Archives 1).
“Human nature never fails to be brought forward in its brightest as well as in its blackest colors” (Chernow 284). Throughout Alexander Hamilton’s life, he not only changed the face of our nation, but also made some decisions that ruined his political and social career. Ron Chernow takes the life of America’s youngest founding father and gives it a whole new level of depth and perspective. The purpose of this essay is to explain the author’s writing style, content, and purpose of Alexander Hamilton as well as give my personal opinion on the book’s material.
As George Washington Carver quoted, “How far you go in life depends on your being tender with the young, compassionate with the aged, sympathetic with the striving and tolerant of the weak and strong. Because someday in your life you will have been all of these. ”. George Washington Carver was a famous African American that became knowledgeable about the uses of peanuts.
The bridge was designed at a time when America was moving toward streamline products, this included the design of bridges. The Tacoma Narrows Bridge was a sleek, graceful looking suspension bridge. Suspension bridges consist of many cables anchored...
