Which is stronger a plank bridge or a arch bridge?
An arch bridge. I think that may have been discovered quite some time ago !!! +++ It was - the Romans used arches extensively, in buildings as a well as for bridges. However, the arch is indeed stronger than the plank, or simple beam, bridge because it transmits the loads to its abutments. You can stiffen a beam bridge by fitting it with vertical side-members, or in larger structures, frames (trusses).
How long do truss bridges span?
For all practical purposes, the span of a beam bridge should not be more than 250 feet. Please see the related link.
Is an arch bridge stronger than a suspension bridge?
Yes. An arch bridge is one of the more efficient ways of building and maintaining a bridge. Beam bridges are not as efficient. For a given span and height, an arch bridge will carry a greater load using less material. The beam structures of a beam bridge can be constructed of wood, reinforced concrete or steel (in increasing order of strength). The beams, however, must be supported by piers or an abutment at each end, which can be made out of concrete, masonry, stone, or steel (or combination thereof). The arch structure of an arch bridge can be constructed of wood, reinforced concrete, steel, or masonry, and the arch can be supported by abutments as described above, or the arch can extended down to the foundation itself. The primary advantage of an arch is that stresses caused by the load on the bridge are converted primarily into compressive stresses that are carried along the arch into the ground. Materials like stone, masonry and concrete are particularly good at carrying these compressive stresses. In contrast, loads on a typical beam-type bridge creates large tensile stresses on the bottom of the beams. Since stone, masonry and unreinforced concrete have very little capacity to withstand tension, none of these materials can be used to make a reliable and efficient beam-type bridge of any significant span.
What is the main difference between an arch bridge and a suspension bridge?
Arch bridges are in the shape of an upside down "U" with mainly steel beans, while supension bridges have one or two Major verticle beams with strong wire connecting to the bridge.
What are 'deep stiffening trusses'?
A truss is a two dimensional structural lattice designed to provide a structural span. They use less material than a simple beam and are lighter. A horizontal truss consists of two horizontal members like beams, upper and lower, that define the depth of the truss, and internal members that form a lattice between these two beams. A stiffening truss is a truss designed to provide extra rigidity or stiffness. A deep truss has a large distance between the upper and lower members.
Why arch bridge is stronger than truss bridge?
because of the support of the circles

How strong is theTruss bridge?
As strong as you make it... Basically a truss system is used when a beam cannot hold its load, so is one way of 'reinforcing' a beam (you could have more supporting colums or use cable stayed/suspension techniques). Its basically stronger than a beam, and 'weaker' than a suspension bridge, but to be honest it's basically as strong as you engineer it. Try searching truss bridge on wikipedia... there's lots of different types and I'm sure it'l have the info.
Does a truss bridge hold more weight than a arch bridge?
No
Why do you have truss bridges?
Truss bridges are lighter than beam girder bridges. They take up more height but are strong and carry loadd in tension and compression rather than bending.
Why is a truss light weight?
a truss puts members at chosen positions where they are the most useful a typical truss is an array of rectangles, with diagonal cross-members, with a triangle at each end a truss is lighter than a solid beam for the same load
Is a bowstring bridge stronger than a truss bridge?
Yes, because the mathematical process they used in that architecture was really well done. +++ Not inherently so, it isn't. The design mathematics are fully understood for any bridge type, and the individual bridge is designed for its own location and intended loads (plus safety factor).
Which bridge is the strongest truss or suspension and why?
Suspension bridges are typically stronger than truss bridges because they can span longer distances and support heavier loads. The design of a suspension bridge allows for the weight to be distributed more evenly, reducing stress on the structure. Truss bridges are better suited for shorter spans and are generally lighter in weight.
Where there truss bridges in Europe before than in America?
Yes there were truss bridges in Europe before the United States. Truss bridges formed in the US because of Europeans, but new American designs were made and that is why the truss bridge is more abundant in the US than Europe today.
How long do truss bridges span?

Why are there metal joints in the middle of the bridge?
because it is less stronger than the sides of the bridge.
