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 are the advantages and disadvantages of an arch bridge?
Disadvantage: An arch bridge requires a very stable foundation. The bridge diverts the tension exerted on it onto the foundations on either side of the bridge. Advantage: It is an economical way to traverse small distances and is able to cope with bending forces
What is the strongest bridge Arch Beam Suspension Truss or Trestle?
well, for my opinion, i think a suspension bridge why: because for of all the cables support the roadway and the two towers looking things at the bottom also supports while for the truss bridge it is only trusses. and if you building a bridge then it depends on what and how you use to build it. good luck!
How many pounds can a toothpick bridge hold?
if you build an arch bridge it can hold more weight then anyother type of toothpick bridge and can hold about 20lbs (if made well) another good type of bridge is the truss bridge it is just as strong as the arch bridge but it has diffrent structures.

What are good things about beam bridge?
They are less likely to be hit by waves Short span beam bridges are very strong.
When was the first concrete bridge made?
Concrete was invented by the Romans and so was the arch, so for thousands of years it has been around. A good example of use of the arch and concrete are the aqua ducts.

What is the definition of a cantilever beam?
A cantilever bridge could be said to be a variation on the basic beam bridge. The roadway of the bridge is held in place by cantilevers, which are long structures, or arms, projecting out into the water, but which are anchored on only one end. A diving board is a good example of a cantilever: although anchored on only one end, it can support a lot of weight. In a cantilever bridge, there are the outer beams, the cantilevers, and the central beam. The outer beams are attached firmly to shore, while the cantilevers are then attached to these outer beams. The cantilevers projecting out from the outer beams, or supporting piers on the opposite shores, are then joined by a central beam. The Forth Railway Bridge in Scotland and the Quebec Bridge in Canada are both famous examples of cantilever bridges.
How strong are bridges?
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.
Why are Arch bridges made of stone?
It's all about compression and tension. Compression is the force pushing in on an object. If you sit in a chair your weight is a compressive force on the chair. Tension is the force pulling on an object. If you hang from a rope your weight puts the rope in tension. Stone is very strong under compression but can break easily under tension. An arch bridge only has compression forces within it so stone is a good material for an arch bridge.
What kind of a bridge is the tower bridge?
No, it isn't. A beam bridge is a beam supported at each end. If you need to cross a ditch one way is to simply span it with a one inch board, then walk across. This is a simple beam bridge. Tower bridge is a bascule bridge. A beam bridge wouldn't do here because the bridge is located downstream of the Pool of London and London docks. Very large ships needed access to this dock area which meant good width and a high overhead clearance. Tower bridge has a tower at each end, with the towers connected to each other by a gantry close to their tops. The roadway, which is not very high above the river, is in two pieces. Each piece is hinged at the tower end, and can be raised to an almost vertical position. When a large ship needs to pass through the bridge, the two bascules are raised, then lowered again as soon as the ship is through. The name Tower bridge has nothing to do with the towers at either end. The bridge is located very close to the Tower of London, a fortress that was put there about 700 years previously.
