Bridges and Tunnels

The primary building materials in cable-stayed bridges are steel, which is used in the cables and also as the reinforcing material in the concrete, which is the other primary building material.

C2H6O could be

1) Ethanol, CH3CH2OH

2) Dimethyl ether, CH3OCH3

The main span is 4,260 feet (1,298 meters) long. That is, the span between the towers. The center of the span changes 12 feet in height between the cold of the winter and the heat of the summer. In summer it is lower than in winter. With the towers being 690 feet high and 4,260 feet apart, the curvature of the earth's surface had to be taken into account when designing the bridge -- the towers are 1⅝ inches farther apart at their tops than at their bases.

The Peace Bridge is an arch bridge consisting of five arched spans under the road and one hill over it at the end near Fort Erie, Ontario. The "hill" is a curve on the side of the roadway that has bars evenly on it. The bridge was originally made for one roadway and a trolley passage way.

The Oresund Bridge is a Cable-stayed bridge. The primary difference between a suspension bridge and a cable stayed bridge is the load bearing structure.

In suspension bridges, this is the cable itself, which transfers the load into large structures set into the earth at the ends of the bridge.

In the cable stayed bridge design, the load is taken primarily by the bridge towers.

A more detailed explanation of the differences is available in the related link.

Truss bridges are made up of triangles which are quite stable since all loads are carried mostly in tension/compression and not bending. Long members may not be stablebecause of buckling in compression, butt most truss designs will account for that.

Steel is heavier than concrete for the same volume, however steel buildings are generally lighter.

This is because steel buildings utilize high strength of steel, so volume of steel in steel buildings is much smaller than volume of concrete in concrete buildings.

In another words in steel buildings much less volume of material is needed for the same strength compared to concrete buildings.

Basically, you have to practice a lot. You could begin by practicing to do the bridge by walking down a wall with your hands. Then walk back up. Keep practicing this. Later, you can try doing the bridge (without a wall) on your bed (our your mom's). After a while, you can do a proper bridge!

bridges are made to cross the rivers by train.

1. Gravel occupies about 70-80% of the volume of concrete.
2. It makes concrete economical
3. Strength of the concrete is determined only by the gravel. i.e., the body of the concrete.
4. Property of concrete determined by the type of aggregate used.
5. Shrinkage is less when larger size aggregate is used.

Arch bridges are made from arches.

Arches are typically made from brick, reinforced concrete, stone or steel. Wooden arches are sometimes used for ornamental bridges, such as decorative footbridges in gardens.

The Chesapeake Bay Bridge-Tunnel

The Tasman Bridge was first opened in 1964. It collapsed when the bulk ore carrier Lake Illawarra struck it early in 1975. The new bridge was not finished until 1977.

well, for my opinion, i think a suspension bridge

why: because for of all the cables support the roadway and the two towers looking things at the bottom also supports while for the truss bridge it is only trusses. and if you building a bridge then it depends on what and how you use to build it. good luck!

London England has the highest suspension bridge in the world

A bridge has three things to complete the foundation to keep it from collapsing. They are called spread footings, caissons and piles. It also has the deck itself.

All these components are also very carefully designed to withstand the various stresses that they will bear in service.

An electrical circuit used to measure an unknown electrical resistance is called a Wheatstone bridge. It is called a bridge because it balances two legs of a bridge circuit.
