Bridges started in ancient Rome‚ and from that point on‚ the understanding of them spread slowly. Both architectures and engineers helped bridges to become a more advanced structure all over the world throughout the years. In the beginning it was known that to build a bridge was very simple‚ all you really needed was natural resources around you‚ such as tree logs and stone. The purpose of bridges is to provide an easier passage way over any interference that your vehicle can not go through such

Bridge Project Questions 1- History of Bridges In the beginning bridges were very simple structures that were built from easily accessible natural resources- wooden logs‚ stone and dirt. Because of that‚ they had ability only to span very close distances‚ and their structural integrity was not high because mortar was not yet invented and rain slowly but constantly dissolved dirt fillings of the bridge. Revolution in the bridge construction came in Ancient Rome whose engineers found that

Basic Research 1. What is a truss and how are trusses used in bridge design? Include the importance of triangular shapes in truss design. A truss is a formation produced by triangular components. The triangular units forming the truss are slim and straight in form. The truss bridges consist of a grouping of triangles. Trusses are used in bridge design to form a series of strong supports using triangles‚ and have the forces of tension and compression acting on them. The importance of triangular

the project is to build a truss that would be able to take a specific amount of downward force remarkably with respect to the weight of the truss itself‚ i.e. to construct a truss that would hold a relatively high efficiency score. And construct the bridge in such a way to as to keep the deflection of the structure at minimal. Introduction First of all‚ what is a truss? In an engineering view‚ a truss is a structure that is made up of series of triangular unit made of straight members that are connected

foot over bridge. Foot Over Bridge Introduction: Before me & my group members start our presentation I would like to share the reason of selecting this topic as our presentation topic. There are many reasons behind that but the main reason is the student of EEE department of our university who died in a road accident while crossing the road in mohakhali a few months ago. Why he was crossing the road while there is a foot over bridge

When people in the United States today hear the term "London Bridge‚" they are most likely to think of one of the most peculiar sights anywhere within the United States that of the London Bridge in Lake Havasu City‚ Arizona. Surrounded by faked-up Tudor buildings and busloads of tourists‚ the large bridge is dwarfed by the majesty of the desert Southwest. The entire enterprise stands as a monument to a deep human appreciation for irony‚ for what else could explain the immense cost and energy that

Balls Bridge and Truss Bridges: A Brief Historical Overview Nathan Holth Foreword: I composed this brief and informal overview of truss bridges and Balls Bridge to put this beautiful historic bridge ’s history and significance into context. A version of this document with full-color photos is available on my website ’s Balls Bridge Page located at www.historicbridges.org/ontario/balls/index.htm which also has more information and photos. The general truss bridge information in this document was

The very first bridges were made by nature itself‚ as simple as a log fallen across a stream or stones in the 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 branches together involved the use of long reeds or other harvested fibers

1.Name at least 6 different types of bridge trusses: Pratt‚ Parker‚ K-Truss‚ Warren‚ Howe‚ Camelback http://www.msnbc.com/rachel-maddow-show/common-types-truss-bridges 2. Name and describe the 3 most common types of bridge truss types: Warren: The Warren Truss uses equilateral triangles to spread out the loads. The triangles reduce the forces to only compression and tension. Pratt: A Pratt truss includes vertical members and diagonals that slope down to the center. The inner diagonals are under
