What types of beams distribute the load on a bridge best?
It would depend on the type of bridge construction.
Was the girder bridge made first?
it is made up of beams to hold it
The beams in an electrical tower form a trapezoid.For which value of x is the shape of the beams an isosceles trapezoid?
5.2
How is a cantilever bridge built?
The basic principle of a cantilever bridge is that the bridge is supported entirely at one end, the rest being held in place by steel pillars or beams.
What is the definition of a cantilever beam?
A cantilever bridge could be said to be a variation on the basic beam bridge. The roadway of the bridge is held in place by cantilevers, which are long structures, or arms, projecting out into the water, but which are anchored on only one end. A diving board is a good example of a cantilever: although anchored on only one end, it can support a lot of weight. In a cantilever bridge, there are the outer beams, the cantilevers, and the central beam. The outer beams are attached firmly to shore, while the cantilevers are then attached to these outer beams. The cantilevers projecting out from the outer beams, or supporting piers on the opposite shores, are then joined by a central beam. The Forth Railway Bridge in Scotland and the Quebec Bridge in Canada are both famous examples of cantilever bridges.
Is a beam bridge held up from above or below the beam?
Beams are generally supported from below; ultimately, the load being bridged may bear at a surface either above, below, or even at the same elevation as the beam. For example, a suspension bridge, with simple beams spanning from side to side, may be attached at both ends of the bridge above the elevation of the beams, suspended below (yet supported from below).
How is a continuous span related to a beam bridge?
It is like more beams and foundations introduced into the structure.
What is a disadvantage of a truss bridge?
It is very hard because it is the strongest.
Are w shape steel beams doubly symmetric or singly symmetric?
The "W" in steel I-beam designations refers to wide-flanged beams. Most wide-flanged beams are symmetric about both the vertical and horizontal axes.
What geometric shape is in a bridge?
a triangle :)
Would you expect to do more repair work to a bridge in a humid coastal city or in a dry inland city?
More work is required on a humid coastal city, as the salt and humidity tend to corrode the steel cables and beams of the bridge.
What influenced the Golden Gate Bridge?
metal beams are place in the ground to support the golden gate bridge these beams are so strong so they can hold the support of the bridge and every thing else
