7029-467: The deck is thinner in proportion to its span, the lines of the structure are continuous, and the shapes of the structural elements reflect the forces acting on them. To create a beautiful image, some bridges are built much taller than necessary. This type, often found in east-Asian style gardens, is called a Moon bridge , evoking a rising full moon. Other garden bridges may cross only a dry bed of stream-washed pebbles, intended only to convey an impression of
7128-491: The lake. Between 1358 and 1360, Rudolf IV, Duke of Austria , built a 'new' wooden bridge across the lake that was used until 1878; it was approximately 1,450 metres (4,760 ft) long and 4 metres (13 ft) wide. On 6 April 2001, a reconstruction of the original wooden footbridge was opened; it is also the longest wooden bridge in Switzerland. The Arkadiko Bridge is one of four Mycenaean corbel arch bridges part of
7227-781: The late 1700s to the late 1800s, reminiscent of earlier designs in Germany and Switzerland. Some covered bridges were also built in Asia. In later years, some were partly made of stone or metal but the trusses were usually still made of wood; in the United States, there were three styles of trusses, the Queen Post, the Burr Arch and the Town Lattice. Hundreds of these structures still stand in North America. They were brought to
7326-427: The load is factored up by a factor greater than unity, while the resistance or capacity of the structure is factored down, by a factor less than unity. The effect of the factored load (stress, bending moment) should be less than the factored resistance to that effect. Both of these factors allow for uncertainty and are greater when the uncertainty is greater. Most bridges are utilitarian in appearance, but in some cases,
7425-639: The oldest timber bridges is the Holzbrücke Rapperswil-Hurden bridge that crossed upper Lake Zürich in Switzerland; prehistoric timber pilings discovered to the west of the Seedamm causeway date back to 1523 BC. The first wooden footbridge there led across Lake Zürich; it was reconstructed several times through the late 2nd century AD, when the Roman Empire built a 6-metre-wide (20 ft) wooden bridge to carry transport across
7524-495: The origin of the word bridge to an Old English word brycg , of the same meaning. The Oxford English Dictionary also notes that there is some suggestion that the word can be traced directly back to Proto-Indo-European *bʰrēw-. However, they also note that "this poses semantic problems." The origin of the word for the card game of the same name is unknown. The simplest and earliest types of bridges were stepping stones . Neolithic people also built
7623-540: The partnership in November 2019. Companies including IKEA and Birkenstock also stopped selling through Amazon around the same time, citing similar frustrations over business practices and counterfeit goods. In September 2017, Amazon ventured with one of its sellers JV Appario Retail owned by Patni Group which has recorded a total income of US$ 104.44 million ( ₹ 759 crore ) in financial year 2017–2018. As of October 11, 2017 , AmazonFresh sold
7722-629: The past, these load models were agreed by standard drafting committees of experts but today, this situation is changing. It is now possible to measure the components of bridge traffic load, to weigh trucks, using weigh-in-motion (WIM) technologies. With extensive WIM databases, it is possible to calculate the maximum expected load effect in the specified return period. This is an active area of research, addressing issues of opposing direction lanes, side-by-side (same direction) lanes, traffic growth, permit/non-permit vehicles and long-span bridges (see below). Rather than repeat this complex process every time
7821-405: The path underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where
7920-423: The popularity of a product sold on any Amazon locale. It is a relative indicator of popularity that is updated hourly. Effectively, it is a "best sellers list" for the millions of products stocked by Amazon. While the ASR has no direct effect on the sales of a product, it is used by Amazon to determine which products to include in its bestsellers lists. Products that appear in these lists enjoy additional exposure on
8019-432: The practice by claiming that Amazon.com was "taking a different approach ... we want to make every book available—the good, the bad and the ugly ... to let truth loose". There have been cases of positive reviews being written and posted by public relations companies on behalf of their clients and instances of writers using pseudonyms to leave negative reviews of their rivals' works. The Amazon sales rank (ASR) indicates
8118-472: The principles of Load and Resistance Factor Design . Before factoring to allow for uncertainty, the load effect is generally considered to be the maximum characteristic value in a specified return period . Notably, in Europe, it is the maximum value expected in 1000 years. Bridge standards generally include a load model, deemed to represent the characteristic maximum load to be expected in the return period. In
8217-416: The project is estimated at $ 32 million. Contractors will finish paving work, striping and lighting improvements, with a final completion date of June 2014. 35°57′25″N 83°55′05″W / 35.957°N 83.918°W / 35.957; -83.918 Bridge A bridge is a structure built to span a physical obstacle (such as a body of water , valley , road, or railway) without blocking
8316-731: The proximity to a major book distribution warehouse in Roseburg, Oregon . Bezos also considered several other options, including Portland, Oregon , and Boulder, Colorado . The company, originally named Cadabra, was founded in the converted garage of Bezos's house for symbolic reasons and was renamed to Amazon in November 1994. The Amazon website launched for public sales on July 16, 1995, and initially sourced its books directly from wholesalers and publishers. Amazon went public in May 1997. It began selling music and videos in 1998, and began international operations by acquiring online sellers of books in
8415-411: The real name of the reviewer (based on confirmation of a credit card account) or which indicates that the reviewer is one of the top reviewers by popularity. As of December 16, 2020, Amazon removed the ability of sellers and customers to comment on product reviews and purged their websites of all posted product review comments. In an email to sellers Amazon gave its rationale for removing this feature: "...
8514-763: The roadways and reduced movement of the upper level when the lower level was installed three decades after the upper level. The Tsing Ma Bridge and Kap Shui Mun Bridge in Hong Kong have six lanes on their upper decks, and on their lower decks there are two lanes and a pair of tracks for MTR metro trains. Some double-decked bridges only use one level for street traffic; the Washington Avenue Bridge in Minneapolis reserves its lower level for automobile and light rail traffic and its upper level for pedestrian and bicycle traffic (predominantly students at
8613-734: The same year, has the span of 90 m (295 ft) and crosses the valley of the Syrabach River. The difference between the two is that the Solkan Bridge was built from stone blocks, whereas the Friedensbrücke was built from a mixture of crushed stone and cement mortar. The world's largest arch bridge is the Chaotianmen Bridge over the Yangtze River with a length of 1,741 m (5,712 ft) and
8712-405: The service in categories that Toys "R" Us had been granted exclusivity. In 2006, a court ruled in favor of Toys "R" Us, giving it the right to unwind its agreement with Amazon and establish its independent e-commerce website. The company was later awarded $ 51 million in damages. In 2001, Amazon entered into a similar agreement with Borders Group , under which Amazon would comanage Borders.com as
8811-653: The simplest and oldest type of bridge in use today, and are a popular type. Some cantilever bridges also have a smaller beam connecting the two cantilevers, for extra strength. The largest cantilever bridge is the 549-metre (1,801 ft) Quebec Bridge in Quebec, Canada. With the span of 220 metres (720 ft), the Solkan Bridge over the Soča River at Solkan in Slovenia is the second-largest stone bridge in
8910-585: The south. It is also mentioned in the start of Mountain Treachery , an Amazon.com e-novel by Matt Reid . In 2011, the Tennessee Department of Transportation began a major rehabilitation project on the bridge. The improvements called for five total lanes of vehicular traffic, two bike lanes and sidewalks, as well as improved lighting. The project was plagued with delays, most notably when two workers were killed in two separate incidents on
9009-554: The time suggested that Amazon planned to eventually roll out 300 to 400 bookstores around the country. All of its locations were closed in 2022 along with other retail locations under the "Amazon 4-Star" brand. In July 2016, the company announced that it was opening a 1,100,000 ft (335,280.0 m) square foot facility in Palmer Township in the Lehigh Valley region of eastern Pennsylvania . As of 2024, Amazon
9108-748: The undertimbers of bridges all around the world are spots of prevalent graffiti. Some bridges attract people attempting suicide, and become known as suicide bridges . The materials used to build the structure are also used to categorize bridges. Until the end of the 18th century, bridges were made out of timber, stone and masonry. Modern bridges are currently built in concrete, steel, fiber reinforced polymers (FRP), stainless steel or combinations of those materials. Living bridges have been constructed of live plants such as Ficus elastica tree roots in India and wisteria vines in Japan. Unlike buildings whose design
9207-433: The weld transitions . This results in a potential high benefit, using existing bridges far beyond the planned lifetime. While the response of a bridge to the applied loading is well understood, the applied traffic loading itself is still the subject of research. This is a statistical problem as loading is highly variable, particularly for road bridges. Load Effects in bridges (stresses, bending moments) are designed for using
9306-496: The widening of Henley Street and the construction of a 54-foot-wide (16 m) bridge connecting the street with South Knoxville. The city initially hired J. E. Griner and Company of Baltimore , but after the company insisted that a 36-foot width was adequate, the city rejected their design. In April 1930, after intense debate, the city selected a design submitted by the Des Moines, Iowa -based Marsh Engineering Company , which
9405-452: The world and the longest railroad stone bridge. It was completed in 1905. Its arch, which was constructed from over 5,000 tonnes (4,900 long tons; 5,500 short tons) of stone blocks in just 18 days, is the second-largest stone arch in the world, surpassed only by the Friedensbrücke (Syratalviadukt) in Plauen , and the largest railroad stone arch. The arch of the Friedensbrücke, which was built in
9504-716: Was expanded to provide website popularity statistics and web crawler data from the Alexa Web Information Service. AWS later shifted toward providing enterprise services with Simple Storage Service (S3) in 2006, and Elastic Compute Cloud (EC2) in 2008, allowing companies to rent data storage and computing power from Amazon. In 2006, Amazon also launched the Fulfillment by Amazon program, which allowed individuals and small companies (called "third-party sellers") to sell products through Amazon's warehouses and fulfillment infrastructure. Amazon purchased
9603-402: Was launched to provide more transparency to sellers by recommending specific products to third-party sellers to sell on Amazon. Products suggested are based on customers' browsing history. Amazon allows users to submit reviews to the web page of each product. Reviewers must rate the product on a rating scale from one to five stars. Amazon provides a badging option for reviewers which indicates
9702-544: Was led by long-time bridge engineer James B. Marsh (1856–1936). Throughout 1930, Knoxville's city council, various local engineers, and the Knoxville News-Sentinel argued relentlessly over the bridge, bickering with one another over everything from the bridge's size to the construction materials to be used. One councilman charged that bribery had taken place. Furthermore, rather than allow Marsh Engineering to choose its own construction supervisor,
9801-690: Was visible in India by about the 4th century. A number of bridges, both for military and commercial purposes, were constructed by the Mughal administration in India. Although large bridges of wooden construction existed in China at the time of the Warring States period , the oldest surviving stone bridge in China is the Zhaozhou Bridge , built from 595 to 605 AD during the Sui dynasty . This bridge
