Introduction

This is the overall mission of the United States Department of the interior and the United States Geological Survey. The two mentioned departments are responsible for bridges and scours which this paper seeks to discuss. Studies have evidently determined that streambed scours are the leading cause of bridge failure in the United States. This results to approximately 60 percent of all bridge failures. The societal repercussions that are associated with failures and the costs that are linked to repair are amplified in Alaska, alternate routes of ground transportation between several cities are not in existence. Bridge culvert damages cost a lot to the economy, for example, in 2002 the damage in Kenai Peninsula was estimated at about 19 million dollars. This led to bridge site examination for scour. Purpose This paper therefore seeks to discuss pier scour in coarse bed and cohesive materials. The purpose of this paper is very open: to know how scour works and why bridges fall down. This is an issue that everyone could be interested in. Several bridges have been witnessed fall down and it has taken my attention to study how the whole process takes place. ...

The Change from One Material to Another in Aircraft Development The method for the choice of materials for aircraft development has changed over the years. For the Flyer, the Wright brothers utilized the first cast aluminium engine block and the major drivers for the material chosen were static strength and weight. The materials used on the main airframe were wood covered with a fabric. Wood is a…
Materials and Corrosion
Crevice Corrosion Corrosion occurring within or adjacent to crevices, which are commonly left at joints, due to small volumes of stagnant corroding fluids is known as crevice corrosion. The most important feature of this type of corrosion is the contact with stagnant solution which takes place in interstices, near seals and in cervices made for nuts and rivet heads. The metals and alloys used in…

According to a survey that was carried out by our firm, we realized that many instances windows were severely damaged. Upon keenly studying the damages, it was realized that it was partly due to environmental factors and partly due to poor maintenance. The damages on the widows caused variations in geometric configuration, composition, porosity and adherence of corrosion products. They also cause…

Quality assurance plays an active role in materials testing. Quality assurance carries out calibration test and manufacturing test. Calibration test is carried out to determine the workability of the measuring properties. Manufacturing test is carried out to determine the adherence to standardization. Some of the tests through which engineering materials are subjected to can be categorized as…

Some of these such as mosquitoes spread diseases such as malaria. Rice and mice is a nuisance. The accumulated heaps of tires are prone to fires. This is because rubber is a substance that can easily catch fire. Once…

These two lanes of traffic were to be constructed on the lower deck level of the bridge. The same conclusion had already been given by Bristol city council. The second recommendation by the group was the removal of the upper part of the bridge that comprises of the stiffening plates. The third conclusion was that the weight of the proposed cantilever beam of the footway could be adequately and…
