Transportation is key in today's society. It’s all about getting from one place to another in the quickest way possible. The inconvenience of going around something or going directly through can be tiring and can take up a lot of time. That’s where bridges come in. A bridge is a structure carrying a road, path or railroad across bodies of water, other roads or any object that may be an obstacle. Although there are many different types of bridges, they all deal with compressible and tensional stress. Each bridge has a certain way with enduring these stresses and each bridge can only hold a certain amount of weight before breaking. The four main types of bridges are: beam, arch, suspension and cantilever. The most commonly used bridge is the beam bridge. The beam bridge is made up of a horizontal structure and two or more vertical structures on either end for the horizontal structure to rest on. Beam bridges can be as simple as a fallen log across a river. In society, engineers generally make beam bridges out of steel and concrete.
Because beam bridges, or any bridge for that matter, are required to carry such heavy loads, engineers use trusses, to help distribute the weight. Trusses are generally made up of triangular or vertical shapes. These triangular or vertical shapes are very effective because a truss has the ability to dissipate a load through the truss work. A truss has the ability to transfer the load from on single point to a more spread out area.
The longest beam bridge is the Lake Pontchartrain Causeway in Louisiana. This bridge spans 24 miles, making it the longest bridge span over water in the world. The causeway was built in 1956 and is still in use to this day. The bridge consists of two lane railed surfaces 80 feet apart and is made up of prestressed panels which are supported by over 9000 concrete pilings. The Lake Pontchartrain Causeway proves that any structure is possible.
Suspension bridges are very similar to beam

    The first being that both the top and the bottom chords for the anchor and cantilever arms of the bridge were mostly designed as straight pieces. This was done to make the construction of the bridge easier and cheaper. The top chords that attached to the anchor and the cantilever arms on the Quebec Bridge were created to be slightly curved, because the engineers believed it looked more aesthetically pleasing. However, the curvature of the chords added to the secondary stresses on the members, and reduced their buckling capacity. The engineering records for the building of the Quebec Bridge has stated in it, “As a rule secondary stresses are much more dangerous in tension that in compression members, which seem to have been the first to give way in the Quebec…

    Each type of design is although, unique in its own way, fulfills the desired goal that the Truss Brides are made for. The purpose of this experiment is to research various bridges and build a similar one that gave the students the highest inspiration. For one case in particular, the bridge design was in-spired by the Pratt Bridge and almost every height, width, and length met the requirements ex-cept for the length on the bottom part of the bridge, it exceeded the maximum height that was asked. Moreover the bridge held a total of 20 pounds before one of the top sticks snapped. Alt-hough it performed a decent job, the bridge could have held more weight if there were more di-agonals to provide more support so the bridge wouldn't break. Furthermore, this bridge fulfilled its goal and held a large amount of weight for such a small bridge. These bridges are also very significant for this planet because it is very resourceful and effective, as well as…

    The related costs, dimensions and load capacity of the bridge It was decided that balsa wood and a Pratt truss would be the most appropriate materials and design to use for this application. This was due to both materials being strong, effective and cheap, allowing the raw materials cost to remain low while also preventing over engineering. This is a reasonable result for a light prototype bridge which only weighs approximately 150g.

    The Brooklyn Bridge, originally known as the East River Bridge, is a bridge in New York City that spans over the East River. It is one of the oldest suspension bridges in the United States. This is the only bridge that connects the borough of Brooklyn to its sister, Manhattan. This bridge, with a huge span of 486.3m, was the longest suspension bridge in the world until 1903. Not only was it the longest, but it was the very first steel-wire suspension bridge in America.…

    The materials that were used to construct this bridge consisted of prestressed concrete, steel casings, prestressed steel, reinforcing steel wire strands and polyethylene. It was built on each side of the land and was eventually connected together in the middle. It was constructed by using a formtraveller (a travelling formwork) and setting up the formwork before positioning and tensioning the cables. They then proceeded to place the reinforcement cement and pouring on the concrete. This was made in a cycle with each cycle being used to make…

    Prohibition did bring even more negative influences than just seen. It had created a unique and illegal nightlife. Brave drinkers went to speakeasies where they drank alcohol. Speakeasies were disguised as different things in a town or city like a funeral home (Muscoreil).To enter the doorman had to remember you,or you said a password, and this is where speakeasy term derives from. New York City had some of the most expensive speakeasies. They were fashionable and gourmet meals were served with the illegal alcohol. ‘21 Club’ was one of the very distinguished speakeasies during this time period (Slavicek).To hide the alcohol, nightclubs went from saloons to homes. Hosts used additives to hide the illegal activity but still get the alcohol. Americans…

    Most suspension bridge roadways were lighter because light structure would put less stress on the cables. However, this light structure would not be a good support for the bridge since it can sway in the wind. Therefore, Roebling decided to use steel wires to support roadways which is why the bridge was considered not only a suspension bridge, but also a hybrid cable-stayed bridge. Just like any suspension bridge, Brookyn Bridge has anchor, approaches, towers, deck, cable, hanger and foundations. The marvel stone towers of the bridge are made of mostly granite with a mixture of limestone and Rosendale cement. These towers are considered gothic towers due to its similar visual to Gothic architecture from medieval period. Additionally, these two towers have arches that can be compared to a Roman architecture “ The Arch of Constantine” (History,…
