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 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

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

Truss Bridge is a one bridge style from a variety other bridges types. The truss bridge is made with a simple skeletal structure. This type of bridges is conceded as a one of the strongest simple design and cost less. Truss bridges were founded early in the history‚ and they were built from wood and iron at the first time‚ which was different than any other bridge that was made of stone. However‚ nowadays‚ truss bridges are made of steel. Truss bridges have many types include‚ the Pratt‚ the Warren
