Triangles are used in trusses to make the unbalanced foces zero in theory.Practically, some unbalanced force remains but it is minor and can be neglected.

∙ 14y agotriangles are the strongest shape
when pushed on from the top, the sides stay staple
they are stronger than arches or rectangles
Wiki User
∙ 13y agoOK it is mainly because the structure can not be moved. this is because all the sides support each other and the weight is distributed evenly
Wiki User
∙ 15y agoAdd structural rigidity to the frame, which translates to less flex in winds and such.
Wiki User
∙ 15y agothe rectangular things on the side are called trusses. so there for the "truss" bridge
Wiki User
∙ 14y agoAs many as it takes.
Truss bridges should have triangles all over.
Openings that are not a triangle (that have 4 or more sides) are not stable.

How long are truss bridges?
the longest span of a truss bridge is 2.1 miles long
What makes Truss bridge stable?
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.
What year was the truss bridge invented?
The exact year the truss bridge was invented is not known. Early forms of truss bridges were seen as earl as 1820 and iron truss bridges did not appear until 1850.
Who invented the truss bridge?
Caleb and Thomas Pratt invented the truss bridge in 1844. Some of the materials that have been used in truss bridges are timber, steel, reinforced concrete, and iron.
Are truss bridges strong for their weight?
Yes they are
What kind of shapes are used in Truss bridges?
The geometric shape used in truss bridges is the triangle.
Two real life examples of a right triangle?
Well, Some Bridges have right triangles in them if the are truss bridges. Also paper footballs are right triangles. Hope that helped a little.
How do forces act on truss bridges?
There are many forces acting on a truss bridge compression, tension, and torsion. The truss bridge uses equilateral triangles to spread out the stress of the load on these forces along the hold structure.
What are facts about truss bridges?
truss bridges are one of the most spaceships in the undergrounds flying
What are 3 different truss bridges in Connecticut?
three different truss bridges in connecticut
Why is a warren truss bridge used?
A Warren Truss Bridge is used to cross certain obstacles. The Warren Truss bridge is Constructed with equilateral triangles so, this relieves of Compression and Tension.
How long are truss bridges?
the longest span of a truss bridge is 2.1 miles long
Are truss bridges rectangular?
No. A truss bridge is composed of trusses
What makes Truss bridge stable?
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.
What common truss types used in bridges?
The type of bridges are: -truss bridge -arch bridge (truss arch bridge) -suspension bridge (suspension truss bridge) -cantilever bridge
Why was the triangulated truss design used in the United States?
In the United States, a premium was placed on inexpensive design, which led to the predominance of the simple triangulated truss design (first used with wooden bridges and later for iron bridges).
Why are truss bridges used less today?
They arent used as much because we have new kinds of bridges that may be more efficient and that are stronger
