Background and Definition Background · There are three states of matter: solids, liquids and gases. · Both liquids and gases are classified as fluids. · Fluids do not resist a change in shape. Therefore fluids assume the shape of the container they occupy. · Liquids may be considered to have a fixed volume and therefore can have a free…
The state of rest and the state of motion of the bodies under the action of different forces has engaged the attention of mathematicians and scientists for many centuries. The branch of physical science that deal with the state of rest or the state of motion of bodies is termed as mechanics. Starting from the…

Careers in Civil Engineering: Construction Supervisor One of the most common jobs of the civil engineers is the construction supervisor. This is also…
An excavator is extremely useful for the construction industry, and can perform gigantic tasks that may not be possible by the human effort. Thus, the excavator has increased the speed of work to a great extent. Efforts are being made to reduce the excavator weight, and make it a quiet function. Description of an Excavator…
American infrastructure is rapidly degrading. Already old and decrepit relative to other nations with developed economic systems, a looming era of budget cuts and limited investment across the board threatens to further undermine the United States’ economic competitiveness as key systems fail. The State of American Infrastructure The collapse of the I-35 West bridge in Minneapolis in…
Soil classification gives generalized information about the behavior and nature of soil belonging to a particular region or location. It also gives scientists, engineers, and agriculturists information about the kind of soil they are going to be dealing with. There are many classification systems in place today that classify soils into different categories. Different countries have different classification parameters…
Lateral measurements to chain lines for locating ground features are known as offsets. For this purpose perpendicular or oblique offsets may be taken . If the object to be located (say road) is curved more number of offsets should be taken. For measuring offsets tapes are commonly used. For setting perpendicular offsets any one of the following…
Introduction Highway and transportation planning can be described as a process of making decisions which concerns the future of a given transport system. The decisions relate to the determination of future demand; the relationships and interactions which exist between the different modes of transport; the effect of the proposed system on both existing land uses…
Composite stone masonry generally consists of a combination of ashlar masonry and rubble masonry. Rubble masonry is generally very cheap, while ashlar masonry gives a pleasing appearance. Hence rubble masonry is used in the backing of the wall while the ashlar masonry is used in the facing, as shown in the above Figure. In order for both the facing and backing of…
