Civil Engineering
Civil Engineering is a profession of designing and executing structural works that serve the general public, like houses, buildings, roads, etc. A Civil Engineer is an engineer trained in the design and construction of public works, such as bridges or dams, and other large facilities.

Advantages of a tilting level?
it does not need the precise set-up procedure to make measurements and thererfore makes working with it easier.
What is soil sampling in civil engineering?
From my understanding soil samples are taken to consider the possible ways a foundation of a building will be layed. That sort of thing. Hope this helps.
the golden gate bridge was on the top of the list for at least 20 years
When was Eitaibashi Bridge built?
The Eitaibashi Bridge is a bridge in Tokyo, Japan. It is considered a perfect place for lovers, it is lit up during the night and during the day the sky blue color shines, and was almost taken down in 1719, but the people stopped it. Eitaibashi crosses the Sumida River and is a major tourist attraction.
The bridge that was built in the 17th century was replace in 1924-1926 by a bridge named Eithai-bashi or Eitai Bridge.
What type of bridge is the Firth of Forth bridge?
There is many different types of makes;
Steel
Iron..
Working stress method of design based on the elastic theory in which materials, concrete and steel are assumed to be stressed well below their elastic limit under the design loads. Working stressess (permissible stress) for the materials are determined by dividing the ultimate or yield stressess by suitable factor of safety values.
Limit state method of design based on limit state concept, te structure shall be designed to withstand safely all loads liable to act on it throughout its life;It shall also satisfy the serviceability requirements, such as limitations on deflection and cracking. The acceptable limit for the safety and serviceability requirements before failure occurs is called a "limit state". The aim of design is to achieve acceptable probabilities that the structure will not become unfit for the use for which is intended, that is that it will not reach a limit state...
How much money do civil engineers make an hour?
i'm starting out at 45,000 in richmond, va. Don't know about experienced ones though. original answer ID2420868128 --------- Depends on what area of civil engineering you go into as well as what level, whether senior management etc. In Australia a graduate Civil Engineer would be looking to start at around $55,000, after a few years of experience the average wage is over $110,000, with most senior positions around $180,000. This is relative to Australia, 2008.
What is the relation between density and compressive strength of concrete?
The span to depth ratio is in place preliminary as a method of ensuring deflections falls within certain limits. As concrete is a multi-phase material and does not behave linearly, it is often complex to calculate expected accurate deflections. codes set out given span/depth ratios as a simpler method or ensuring deflections remain in given limits. These ratios have been derived empirically from testing.
The compressive strength of concrete as a material does not vary with varying span/depth. However, the amount of the concrete section which is in compression will vary with span and depth due to changes in the applied moment and increase/reduction of the internal lever arm.

yes
it is a structure because it has a foundation, and other objects to help support it stand serve it's purpose. Also, every thing you encounter is a structure. Even you and i are structures. :)

What is the biggest bridge in California?
Golden Gate Bridge But I'm Not Sure Cause It Might Be A Different Bridge
Well it depends on what your reffering to long, wide, fat? Because there are a lot of bridges that are big.
What is a major problem for suspension bridges?
Although suspension bridges are among the longest bridges, and most are well-built, the design does include features that make them more susceptible to failure. Rather than a rigidly-connected skeleton, a cable bridge is held in place by its own weight, which maintains a constant tension.
The cables supporting the roadway are balanced, and if any fail, the change in weight can cause a complete collapse. Cables must be inspected regularly for corrosion, wear, or slippage.
Shifts in the foundation of any bridge can cause it to fall, but because there are fewer supports in the cable bridge, any change will tend to have greater effect.
High winds can cause structural failure of a poorly-designed bridge by causing swinging oscillations known as "aeroelastic flutter." This causes a twisting motion that can warp or crumble the bridge deck.
Why do railway tracks have gaps in them?
Railway tracks have gaps to allow for expansion when the tracks heat up. As the tracks get hotter, they expand and get slightly larger. Without the gaps, the tracks would buckle from the force of the expansion. They have fishplates located between the joins to force the rails back into lateral alignment and thus prevent derailments.
In modern continuously welded rail these gaps are often cut on a diagonal to prevent this misalignment. The thermal expansion and contraction of rail track is minimal and the forces push to the outside rather than along the rail.
They are also there because segments of rail have traditionally been required to be removed and replaced easily and so had to be made a manageable length.
Heat expands metal, to prevent buckling in the rails the tracks are in pieces with gaps. Another reason is in case of lighting strike the electric current can only travel as far as the first gap, this preventing electrical charge getting to a train car or electrical box.
because the railway lines expand during the summer and by the friction of the train with it . if the gap is not kept the rail lines would expand and break. so to avoid the breaking of the rails the gap is kept
There is gaps between railways because during summer when the sun will heat the rail which is made of iron will obviously expand.
After some calculation an approximate distance is left between them.
After this answer you will ask but what in winter and how does the train pass on the gaps?
So this gap is nothing for the train. It is left so that during expansion when the railways will expand the rail will not change direction.
For e.g:-
imagine when you take 2 drinking pipe and joint them together it will change direction or even damage.
when heat is supplied to a substance or material it will expand.during summer the tracks get heated as a result it will expand. if gaps are not provided, that may result in the bending of tracks.
Railway tracks have expansion joints to prevent them from warping when they expand during very hot weather. The metal on railway tracks can conduct a lot of heat during sunny periods.
There are small gaps between the length of the railway track because when the temperature is hot the metal will expand and cause the train to crash. So if there is a gap between the length of the train tracks the metal wont join together and cause the train to crash. When the weather is hot have you ever noticed that the trains go slower? Thats just in case the metal joins together.
A.thermal conductivity
B.specific heat
C.thermal expansion
D.thermal insulation
The gaps are there to allow for the expansion (lengthening) of the rails in hot weather. Without any gaps, the rails would buckle and go out of alignment.
How long do truss bridges span?
For all practical purposes, the span of a beam bridge should not be more than 250 feet.

used for making stuff like childrens toys etc
Softwood has a huge range of applications: it is the primary material used for building components, and is also found in furniture and other products such as millwork (mouldings, doors, windows). Softwood is also used in the production of paper, and for various types of board such as MDF (medium-density fiberboard). The finer softwoods have many special uses.
they are used for making window frames,doors,frames,t.v. stands,flooring and beds. people use these all the time actually even to make toys for children.
