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?
Triangles are the better option to use as legs of a bridge because they widen at the bottom, giving more support. It essentially gives it double the amount of legs, since each one has two points at the bottom.

If the above picture was a bridge, see how each "leg" ends with two points touching the ground? This is why it is more supportive.
Triangular supports strengthen towers and bridges by preventing collapse, or racking, of rectangular structures.
Without the center triangular beam, these rectangles would be miore likely to collapse like a 'house of cards' from relatively light static and dynamic loads.
Because the triangle is a very strong shape.
because it makes the bridge more strong ,and truss bridges are very long so it is important
Triangles are the strongest type of shape. It is very sturdy, but takes up little space. It is the best for building bridges.
To a limited degree, yes. However, very strong tornadoes will destroy just about any structure they hit, including truss bridges.
It is very light, and the equilateral triangles spread out the forces.
Economical, easy to construct and repair, very strong.
Suspension bridges are one of the oldest engineering forms, dating back to the 4th century. Modern suspension bridges were made possible by the web truss, invented by John Augustus Roebling. The web truss made a very sturdy, rigid structure that could withstand storms, wind forces, and heavy loads.
the earliest written record of a bridge is the one on build across the Euphrates around 600BC described by Herodotus, the 5th Greek historian).
Triangles are used in structures because a triangle is a very stable shape that cannot be stretched or squashed easily - unlike rectangles which can easily become parallelograms.
Advantages: Very sturdy, can have several cracks in structure before breaking disadvantages: best for short distances, not attractive, hard to maintain
Triangels are the strongest shape so make a triple triangle design i aced it that way +++ The plank bridge is the weakest as it is just a simple beam with no central support or stiffening for the span. The other two can be designed to comparable strength for a given span, but work in somewhat different ways: the truss bridge acts as a beam stiffened by the truss frames, the arch transmits the forces from the centre to its abutments.
yes very
it helps trains cross since the truss bridge is VERY strong and stable :D
There are many similarities of stage trusses, but which one is the most stable?The most stable and stable structure of a stage truss is a triangular truss. In physics, a triangle is the most stable structure, and it also saves the most material. So in some occasions, using a triangular truss is a very wise choice.The foldable triangular stage truss produced by SHIZHAN Group has a stable and stable truss structure. Compared with trusses of the same specification, it has a greater load capacity and span. The folding triangle truss is a pin interface and has a fast installation speed. The stage truss can be closed when not in use, which can save freight and storage space to the greatest extent. It is a perfect truss in all aspects of the truss.SHIZHAN Group is China's largest company group of trussed stage barriers.
