Why are arch bridges better than than beam bridges?
Arch bridges are better because they transfer the weight down the archs and into the grownd unlike the beam bridge where it transfers it's weight through the beams wich break more often than arch bridges.

Is Neptune's gravity stronger or weaker than earth's gravity?
it is stronger
Is a volcano stronger than an earthquake?
it depends how strong the earthquake is some can be stronger than a volcano or than a volcano can be really strong
Is wind stronger than fire?
No ..Fire Is Way Stronger Then Wind
When a ceramic rod is broken into two parts in tension each part will apparently be stronger than the original whole why?
Because the break occurred at the weakest point in the rod. All other points, in both parts, are stronger than that point was.
Why arch bridge is stronger than truss bridge?
because of the support of the circles
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).
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.
Does a truss bridge hold more weight than a arch bridge?
No
Why would bridge engineers choose a arch bridge design over other bridge designs?
Becuase bending moment in the middle of the bridge bending moment is less than ordinary or straight bridge and more strength
Why are there metal joints in the middle of the bridge?
because it is less stronger than the sides of the bridge.
How does an arch support itself?
Bridges are made up of triangles joined together to form a truss. Triangles are very strong because they carry weight in tension and compression instead of bending and can hold a lot more than a beam that bends can

What are some advantages and disadvantages of a cable stayed bridge?
The main advantage of a cable-stayed bridge is that it is under compression by the cables which makes it stronger. The main disadvantage of the cable-stayed bridge is that it is more susceptible to wind than other types of bridges.
What shape is stronger an arch or a triangle?
Well, after studying extensively on this subject for countless years at the University of Cambridge, my colleagues and I have determined that, in fact, an arch is BY FAR the stronger of the two shapes. It is a common misconception that a triangle is stronger, and it has been my life work to prove this fact wrong. That is all.-Yea, after reading this I have to agree 100%. I remember working on a science project in the fifth grade and this tool bag argued with me over this point by saying that triangles were stronger. We went with his idea, which led us to FAIL our PROJECT.-This sounds right and I would agree. However, I must add that, a GROUP of triangles together can be potentially stronger than an arch. A single triangle is far weaker than an arch.
What was the sydney harbour bridge?
The Coathanger because of its arch-based design, although this usage is less prevalent than it once was.
