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.

Why is the pointed arch seen in Gothic architecture structurally more stable than the rounded arch used earlier?
its direct weight downward into the ground.....
Is arch bridge stronger than any other bridge type?
Because it has more support in its arches.
What are some architectural designs in Rome building?
The Romans effected what historians call the Roman architectural revolution or concrete revolution. This involved the extensive use of concrete, the barrel (simple) arch and the vaulted arch. These three elements enabled the Romans to go beyond Greek methods of construction which used cut-stone and post-and-beam or post-and-lintel structures. The Romans developed a type of concrete (opus caementicium) which was as resistant as modern concrete and also set underwater (and therefore could also be used to build docks for ports, dams, aqueducts and bridges). It was less fluid than modern concrete and had to be layered by hand. It was made by mixing a volcanic rock called pozzolana (which is named after Pozzuoli, a suburb of Naples) with lime as a binder and the addition of rubble from stones, bricks or pottery shreds as aggregates which added body to it. Concrete had technical and practical advantages. It was exceptionally strong and could span great distances when shaped into arches, vaults and domes as it could be moulded. It was layered into a formwork and it took the shape of its container. It did not require skilled labour and therefore was cheaper. It was much faster for construction than laborious masonry walls. It was safer because concrete vaulted roofing was fireproof, unlike the wooden-beamed roofs of traditional construction post-and-lintel methods. The potential of the previously little used arch and vault, was fully exploited for the first time. The Romans were the first to fully appreciate the advantage of these structures. The (simple, barrel) arch has a strong load- bearing capacity. The vault (vaulted arch) has an even greater load-bearing capacity and its structure is suited to support large roofs. Their construction in concrete made them easier to build and even stronger. This led to the use larger and monumental arches and vaults on a grand scale. However, the Romans did not abandon masonry arches and vaults. The vaulted arch came into two forms: the groin arch is formed by two to four intersecting barrel (simple) arches and the rib arch, where the intersecting arches were not of the same diameter; the ribbed arch has intersected arches of different diameter.
What are facts about the contribution of ancient Rome?
Rome developed the arch which was capable of supporting weight more efficiently than the columns used by the Greeks, Egyptians, and others. They also extended the arch into a tunnel-like structure called the vault, and they ran the arch in a circle called the dome. These architectural innovations have long outlived the Romans, and the Jefferson Memorial in Washington DC is a copy of a domed temple in Rome called the Pantheon, built by Marcus Agrippa. The arch was also used for bridges and aqueducts. Rather than rely on huge blocks of stone which had to be quarried and transported from a great distance, the Romans developed a kind of instant stone; concrete, which we still use today. The Romans also had hydraulic concrete which hardened when wet. The infamous Roman puppet Herod the Great built a port city called Caesaria where no natural harbor existed. Forms were erected in the water, and the hydraulic concrete was poured into them. Caesaria was similar to the two "Mulberry" harbors used at Normandy in June 1944, except that these were made of preformed concrete cassions which were towed into place and sunk. Although constructed with concrete reinforced by steel I-beam, the modern circular sports stadium was certainly inspired by the Roman amphitheaters which were the most difficult to build of all Roman architecture.
Is the brachiocephalic artery longer on the left side than on the right?
Trick question.... you only have 1 brachiocephalic trunk. It comes off the right side of the aortic arch (right side from anatomical position, or the patient's perspective) and immediately splits into the subclavian artery and the common carotid artery. On the left side of the arch the subclavian and common carotid branch directly off the aortic arch. Hopefully this makes sense.
Are arch bridges better that beam bridges?
arch bridges can support more weight than beam bridges but for price i say beam won.
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).
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.
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.
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.
Why bridges are made?
bridges are made to cross the rivers by train.
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
Why is an I-Beam stronger in its weight than a simple rectangular beam?
The vertical portion of the I-beam resists shear force better than a rectangular one. The "I" portion also deflects force because of its design.
Where does the stability in buildings come from?
The stability in buildings mostly come from the foundation. The better the foundation, the stronger the building would be. That is why the construction of buildings take longer during the beginning, where they lay the foundation before "stacking" up to form the upper floors. Other factors may include the shape of the building. Almost 99.9% of buildings have a larger base area than the top, or the building would collapse or topple over easily due to its high center of gravity. A triangular shape structure would be the strongest, as observed from card structures and the Transamerican Pyramid in San Francisco. However, most building are usually four-sided as it is easy to construct and able to be stacked up to great heights. There are also many different kinds of bridges and they each get their strength from a different design. Among the different types of bridges there are Beam, Cantilever, Truss, Cable-stayed, Arch, and Suspension (there are others). * Beam bridges are just horizontal beams stretching over a span and supported by piers. The weight of an object on the bridge is transfered onto the piers. * Cantilever bridges are horizontal beams supported on only one end by a pier. Usually two cantilevers are combined to cross a span. * Truss bridges are composed of variety of elements. They have a solid deck and lattice structure sides. * Cable Stayed bridges and Suspension bridges get there strength from the cables used to tie their spans to their piers. * Arch bridges use the natural strength of the arch shape to tie their surface to wider spanned piers.
