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

Truss bridges have many advantages that make it more useful for everyday use. The truss bridge is very economical to build and uses very few resources. It uses light materials and small loads of timber or whatever it is being made of. It is also one of the stronger bridges that can be built. The trusses on top of the bridge make it very strong because the triangle shape takes away much of the pressure and spreads the pressure to the triangles and takes it away from the road part of the bridge. The

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

Bridge Design Process In order to begin we must start our design process with the first step. We have to identify the need. The scenario is that we need to connect two pieces of land or structure so that a car must be able to pass through it. In this project we are to design and construct a bridge for a matchbox car. The bridge must be made of balsa wood and glue only. It must support its own weight‚ the load of the matchbox car‚ and additional weights that will be added. Next we must

always on the top of the list. But when thinking about Australia there are two super structures that come to mind‚ The Sydney Opera House and The Sydney Harbour Bridge. In this short report it can be found small history along with a short description about the Sydney Bridge. II. Main Body II.1 History The first plans to build a bridge actually goes back to year of 1815‚ but it wasn’t until 1922‚ after being delayed manly because of the WWI‚ that the parliament approved the laws for the construction

“The Old Man at the Bridge” by Ernest Hemingway An old man with steel rimmed spectacles and very dusty clothes sat by the side of the road. There was a pontoon bridge across the river and carts‚ trucks‚ and men‚ women and children were crossing it. The mule- drawn carts staggered up the steep bank from the bridge with soldiers helping push against the spokes of the wheels. The trucks ground up and away heading out of it all and the peasants plodded along in the ankle deep dust. But the old man

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

"Put Yourself in My Shoes" "Put Yourself in My Shoes" is one of the longest and most complex stories in the collection‚ and one of its finest. In addition‚ it brings together a number of the themes and images that have recurred throughout the book. For example‚ it depicts the kind of interaction between two couples that we have seen in "Neighbors" and "What’s in Alaska?"; in this case‚ the Myerses go to visit the Morgans‚ whose house they had lived in for a year while Professor Morgan and his wife
