Skatepark
A skatepark, or skate park, is a purpose-built recreational environment made for skateboarding, BMX, scootering, wheelchairs, and aggressive inline skating. A skatepark may contain half-pipes, handrails, funboxes, vert ramps, stairsets, quarter pipes, ledges, spine transfers, pyramids, banked ramps, full pipes, pools, bowls, snake runs, and any number of other objects. History The first skatepark in the world, Surf City, opened for business at 5140 E. Speedway in Tucson, Arizona on September 3, 1965. Patti McGee, Women's National Champion, attended the grand opening. The park had concrete ramps and was operated by Arizona Surf City Enterprises, Inc. A skatepark for skateboarders and skaters made of plywood ramps on a half-acre lot in Kelso, Washington, USA opened in April 1966. It was lighted for night use. California's first skatepark, the Carlsbad Skatepark opened on March 3, 1976. The World Skateboard Championships were held here on April 10, 1977. It operated un ...

Wuppertal Eulenkopfweg 084
Wuppertal (; "''Wupper Dale''") is, with a population of approximately 355,000, the seventh-largest city in North Rhine-Westphalia as well as the 17th-largest city of Germany. It was founded in 1929 by the merger of the cities and towns of Elberfeld, Barmen, Ronsdorf, Cronenberg and Vohwinkel, and was initially "Barmen-Elberfeld" before adopting its present name in 1930. It is regarded as the capital and largest city of the Bergisches Land (historically this was Düsseldorf). The city straddles the densely populated banks of the River Wupper, a tributary of the Rhine called ''Wipper'' in its upper course. Wuppertal is located between the Ruhr (Essen) to the north, Düsseldorf to the west, and Cologne to the southwest, and over time has grown together with Solingen, Remscheid and Hagen. The stretching of the city in a long band along the narrow Wupper Valley leads to a spatial impression of Wuppertal being larger than it actually is. The city is known for its steep s ...

Davis, California
Davis is the most populous city in Yolo County, California. Located in the Sacramento Valley region of Northern California, the city had a population of 66,850 in 2020, not including the on-campus population of the University of California, Davis, which was over 9,400 (not including students' families) in 2016. there were 38,369 students enrolled at the university. History Davis sits on land that originally belonged to the Indigenous Patwin, a southern branch of Wintun people, who were killed or forced from their lands by the 1830s as part of the California Genocide through a combination of mass murders, smallpox and other diseases, and both Mexican and American systems of Indigenous slavery. Patwin burial grounds have been found across Davis, including on the site of the UC Davis Mondavi Center. After the killing and expulsion of the Patwin, territory that eventually became Davis emerged from one of California's most complicated, corrupt land grants, Laguna de Santos Callé ...

Structural Load
A structural load or structural action is a force, deformation, or acceleration applied to structural elements. A load causes stress, deformation, and displacement in a structure. Structural analysis, a discipline in engineering, analyzes the effects of loads on structures and structural elements. Excess load may cause structural failure, so this should be considered and controlled during the design of a structure. Particular mechanical structures—such as aircraft, satellites, rockets, space stations, ships, and submarines—are subject to their own particular structural loads and actions. Engineers often evaluate structural loads based upon published regulations, contracts, or specifications. Accepted technical standards are used for acceptance testing and inspection. Types Dead loads are static forces that are relatively constant for an extended time. They can be in tension or compression. The term can refer to a laboratory test method or to the normal usage of a material ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Steel
Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, weapons, and rockets. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile, or soft and easily formed. In steel, small amounts of carbon, other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Street Skateboarding
Street skateboarding is a skateboarding discipline which focuses on flat-ground tricks, grinds, slides and aerials within urban environments, and public spaces. Street skateboarders meet, skate, and hang out in and around urban areas referred to as " spots," which are commonly streets, plazas or industrial areas. To add variety and complexity to street skateboarding, obstacles such as handrails, stairs, walls, flower beds, bins, park benches, picnic tables, and other street furniture may be traversed as single tricks or as part of a series of consecutive tricks called a "line." History During the late 1980s and early 1990s, street skateboarding evolved as a new approach to skateboarding, using elements taken from the other existing skateboarding disciplines. Instead of drained swimming pools and purpose-built skateparks, skateboarders began to use urban areas and public spaces. For example, in the 1980s, Philadelphia's LOVE Park transformed from a place where businessp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Concrete
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined. Globally, the ready-mix concrete industry, the largest segment of the concrete market, is projected to exceed $600 billion in revenue by 2025. This widespread use results in a number of environmental impacts. Most notably, the production process for cement produces large volumes of greenhouse gas emissions, leading to net 8% of global emissions. Other environmental concerns include widespread illegal sand mining, impacts on the surrounding environment such as increased surface runoff or urban heat island effect, and potential public health implications from toxic ingredients. Significant research and development is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerials (skateboarding)
Aerials (or more commonly airs) are a type of skateboarding trick usually performed on half-pipes A half-pipe is a structure used in gravity extreme sports such as snowboarding, skateboarding, skiing, freestyle BMX, skating, and scooter riding. Overview The structure resembles a cross-section of a swimming pool, essentially two concave ram ..., pools or quarter pipes where there is a vertical wall with a transition (curved surface linking wall and ground) available. Aerials usually combine rotation with different grabs. Most of the different types of grabs were originally aerial tricks that were performed in ditches, empty pools, and vert ramps before flatground aerials became common. Aerials can be executed by ollieing just as the front wheels reach the lip of a ramp, or can be executed simply by lifting the front wheels over the coping (or lip). The former is preferable on shallower ramps where the skateboarder has less speed to lift them above the ramp. Common aerial t ...
