CAREY FOSTER BRIDGE Introduction The Carey Foster bridge is an electrical circuit that can be used to measure very small resistances. It works on the same principle as Wheatstone’s bridge‚ which consists of four resistances‚ P‚ Q‚ R and S that are connected to each other as shown in the circuit diagram in Figure 1. In this circuit‚ G is a galvanometer‚ E is a lead accumulator‚ and K1 and K are the galvanometer key and the battery key respectively. If the values of the resistances are adjusted so

dictionary‚ a bridge is a structure carrying a road‚ path‚ railroad‚ or canal across a river‚ ravine‚ road‚ railroad‚ or other obstacle. Bridges are essential for transportation. Whether it’s a canyon‚ or a body of water‚ bridges allow travel over those gaps from one part of land to the other. The world would be forever changed without bridges. The five main types of bridges are arch bridges‚ truss bridges‚ beam bridges‚ suspension‚ and cable-stayed bridges. Arch bridges are bridges that use arch

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

Abstract The Golden Gate Bridge is a well-recognized landmark in the United States. This report provides you numerous information about one of the most astonishing suspension bridges in the world‚ it as well enlighten you with the history‚ design and the way that they have managed how to maintain the safety while construction was going on. The idea of a bridge linking the city with its neighbouring counties was appealing‚ but the mile-wide gap between San Francisco and Marin presented huge challenges

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
