Bridges and Tunnels

Apart from bridge building, arches are commonly used for doorways/openings. Throughout history arches have been used to spread vertical loads to create openings. Examples range from small garden arches to the Colosseum.

It all depends on the dimensions of the steel beam

The longest span an arch bridge can go is relevent to the radius of the arch.

A bridge is a way to connect two networks. For example, if a user has two or more computers connected to a wired network, and one of those wired computers is connected to a wireless network, the computer connected to both the wired and wireless networks could be used as a bridge. With the bridged networks, the wired computers could access the wireless network.

A suspension bridge is designed to have cables suspended between towers plus vertical suspender cables that carry the weight of the roadway below. The Golden Gate Bridge is a great example of this type of bridge and is considered an engineering marvel.

( A bridge was designed as a vertical curve above a train line according to the gradients (g 1 =+3.6%g g 2 =-2.9%) , if you know that the designed length of the bridge equal to 530 m find the following : a) Rate of change in gradient for each station . b) Elevation and station for each of intersection and end points if you know that the elevation and station of start point are 34.5 m and 23 + 00 respectively . c) Check if the design is ok if you know that the level of train line is 35.00 m and the minimum allowable height of the bridge at mid -point is 5.2 m

The nasal bones make up the bridge of your nose. There are two small oblong bones, varying in size and form in different individuals; they are placed side by side at the middle and upper part of the face, and form, by their junction, "the bridge" of the nose.

A riveted connection requires much more force to break the connection than a bolted connection. Furthermore, a bolt can become loosened by vibration which is highly unlikely in a riveted connection. Therefore, a bolt is weaker than a rivet.

The beautiful Golden Gate Bridge is the large suspension bridge located in San Francisco, spanning the gateway between the opening of the San Francisco Bay and the Pacific Ocean. The length of the bridge from abutment to abutment is 1.7 miles, the width is 97 feet and the bridge weighs around about 887 thousand tons including anchorages and approaches. The bridge is painted Orange Vermillion, also known as International Orange, and needs constant touch ups to make sure the salt content in the air does not erode it. When the Golden Gate Bridge was completed in 1937, it was the longest suspension bridge in the world. It is now the 2nd longest suspension bridge in the United States and the world's 9th longest suspension bridge.

Bridges were ivented for the simply reason...to get over them. Bridges that go across lakes,rivers,any land of water were created so that you can get over without having to get in a boat and travel among the water. Its common sense, i have not researched this so no promises but i have learned this in school, And like i said its simply common sense.

The Civil Engineering Data Standards manual states the density of many grades of concrete. Standard density for fresh M-25 concrete is: 2414 Kg/ M3.

I think so. But who am I to tell u wat to do..

It has to do with the design of the bolts. The reason that head of the bolt is oval in shape. The head of a bolt fit flush into the bar and set in opposing sets is so that a piece of dragging equipment will not shear off all the bolts in a joint but rather the just the nuts one side. As a result if the hole is not oval on one side there would be no way to tighten or loose the bolts in a joint.


Second Answer: They would be oval shapes so when contraction or expansion happens they wont snap.

A Cantilever bridge is built from iron, structural steel and prestressed and reinforced concrete. These materials make the trusses, box girders, vertical columns and the canitlever itself.

The fear of bridges or of crossing them is Gephyrophobia.

According to the U.S. Bureau of Transportation Statistics, there are approximately 600,000 bridges in the United States. The number worldwide must be significantly greater, though not proportionally as the U.S. is a richer nation and has more territory requiring more bridges than most. I'm aware this is not a complete answer, but the previous suggested answer was "400", and that is WAY off.

Bridges have been built since the stone age, it is impossible to say where or when the first one was built.

The role and application of engineering science is important based on inventing and creatinig new ideas. It is from these roles in engineering sciene , we develop and enhance answers to our problems. we do this such that experiments are carried out and prove whether or not our predictions were made accurately or inaccurately..

Often a borrower needs a bridge loan to facilitate the financing a property for a short period of time. A bridge loan is a specially designed form of financing that is used when a borrower is expecting to sell a property quickly or refinance it within the near future.

It is called Tower Bridge.

Or you might be talking about the one that was on Harry Potter and the Half-Blood Prince, which is the wobbly bridge, but it's proper name is the Millenium Bridge.

Advantages: Very sturdy, can have several cracks in structure before breaking

disadvantages: best for short distances, not attractive, hard to maintain

Yes. Any of the engineering majors are challenging as they require extensive math, physics, and other science related classes. It takes a lot of dedication and hard work to become an engineer. That is why they are paid better than other 4 year degrees.

It also depends on your hardwork, motivation and interest.
