The Tacoma Narrows Bridge was the third largest in the world in 1940. Unfortunately that wouldn’t last too long. On November 7th‚ 1940 only four months after being open it collapsed due to violent swaying and flexing. Some of the reasons for its collapse were that it was put in an area of Tacoma that was prone to high winds and the engineer used solid girders instead of open trusses to cut costs. Another issue that engineers later learned about was its lack of aerodynamics. With that said we will

The context includes the preexisting conditions and the content of the speech. Yesterday I asked my roommate‚ Toby Briggs‚ if he wanted to give a short speech on any topic he chose. He was beyond interested in giving a speech of his choosing. Without delay‚ he chose the topic of the K-T boundary. Toby went

The title‚ "An Occurrence at Owl Creek Bridge" is an extremely interesting title making you want to read the story. The word "Occurrence" in the titlet made me want to find out what the "Occurrence" was. The title made me start thinking about what the story really could be about. The main character is a planter named Peyton Farquar. Farquar wanted to be a soldier in the civil war fighting on the Confederates side‚ but instead of fighting he stayed home to care for his family and farm

Grabber: Truss bridges are a good creation because it helps with traveling since it is a sturdy and cheap efficient bridge to make. Define truss bridges and explain how they are different from other bridges: A truss bridge is a bridge whose load-bearing super structure is composed of a truss‚ a structure of connected elements forming triangular units. The connected elements are typically straight. The truss bridge is different because it uses triangles‚ its way brought about in the 19th and 20th

This bridge was one of the bridges that we thought as a group that can hold the much weight because of its structures. At first it was really hard to figure out on how to build it but three minds always work better then one so as we figured out the best way to built it we would test it ourselves. The Pratt truss was first developed in 1844 under patent of Thomas and Caleb Pratt. Since the 1840s through the early twentieth century‚ the Pratt has diagonals in tension‚ verticals in compression‚ except

Bridges are a very important part of transportation. They are used to span things such as water‚ valleys or other roads. The design of a specific bridge is directly dependent on what it has to cross‚ where it is being built‚ and the materials that are being used. The original bridges were simply trees‚ which by chance had fallen over small rivers or streams. However‚ as time went on‚ bridges became much more advanced‚ including suspension bridges‚ arch bridges and beam bridges. In suspension

Golden Gate Bridge Lead Designers/Engineers. The First proposal for the Golden Gate Bridge came from James Wilkins‚ who at the time was an engineering student. The cost of James Wilkins Bridge was unrealistic at the time which was 100million dollars‚ but none the less it set the bar for other bridge engineers to try to work out a cheaper solution. During this time a young Joseph Strauss had graduated from the University of Cincinnati with a degree in Business and Economics. Joseph was an avid

The purpose of accelerated bridge construction is to ensure the project planning‚ procurement‚ and logistics approach are modified to ensure tasks with long lead times‚ traditionally completed onsite‚ are of highest priority and completed using creative solutions. Multiple scenarios require the need for accelerated bridge construction technologies; where a bridge is being constructed or reconstructed over an existing roadway in use‚ where a bridge is being reconstructed or replaced for an existing
