What materials are used to build a cantilever bridge?
The materials that are used to build a cantilever bridge are typically structural steel, iron, and also prestressed and reinforced concrete. The materials listed create the multiple parts of the bridge. These include the trusses, vertical columns, box girders, and most importantly, the cantilever itself.
Which president served the longest in the senate before becoming president?
President Lyndon B. Johnson served the longest in the United States Senate before becoming president. He was in the senate for twelve years.
engineers have to find the right area to build a bridge that is strong enough to support the weight and things from mother nature. The long columns are then put into place above the water, then sunk.
What was a view from the bridge about?
Eddie Carbone, his wife Beatrice and his niece Catherine live in Brooklyn. Beatrice's Sicilian cousins come over as illegal immigrants and stay with the Carbones. Catherine is immeadiately attracted to Rodolpho. However, Eddie doesn't want Catherine to be with Rodolpho. This could be seen as simply protective as Eddie is like a father to Catherine. Catherine and Rodolpho end up getting engaged, although Eddie says that Rodolpho just wants to be made an American citizen.
However throughout the play we are given hints that Eddie has unnatural and inappropriate feelings for Catherine. At the end of the play our suspicions are confirmed when Beatrice tells Eddie to his face that he wants Catherine. Eddie then calls Immigration telling them that Rodolpho and his brother Marco (Beatrice's cousins) are there. Marco then gets arrested but Rodolpho doesn't as he is engaged to Catherine. Marco publicly tells the witnesses of his arrest that Eddie was the one who called immigration which is one of the worst things someone could do in that society.
On the day of Catheirne and Rodolpho's wedding Marco is released on bail and comes to beat up, and assumedly kill Eddie.Eddie brings a knife to the fight and eventually Marco turns the knife on Eddie, killing him. Eddie dies in Beatrice's arms, and his last words are "My B.!" showing that he does love Beatrice still.

What is the golden gate bridge's load capacity?
The maximum weight allowed on the bridge is 3000 lbs/vhicle. In engineering, the engineers build in buffer ("play room") to everything. Meaning if the real limit was 3000, they would rate it at 15000 lb. (or some safe number). Put it another way, if the weight limit was 3000 lb, you can be sure that the actual TESTED or theoretical limit would be MUCH higher.
The same is true of everything in engineering, Civil engineering, Architectural science, mechanical science.

Why triangles are very important in the truss bridges?
Engineers have been building triangular bridges, because it is the most common, and one of the most durable when it comes to handling weight. Because it is in a triangular form it is aero dynamic, and if the truss can hold, it will survive strong winds and small earthquakes?

Cantilevers are long projecting beams or girders fixed at only one end, used mainly in bridge construction. They are used a lot for a range of things for example: canopies, balconies, sidewalks outside the trusses of bridges etc...
How do bridges withstand external forces?
tension pulls on the bridge, compression acts upon the supports of the bridge, and shear is created because of the wind blowing on the wind. extreme weather or earthquakes may cause torsion, but it's very rare that you'll find that in a bridge.
