Sledding In Germany
Sledding, sledging or sleighing is a winter sport typically carried out in a prone or seated position on a vehicle generically known as a sled (North American), a sledge (British), or a sleigh. It is the basis of three Olympic sports: luge, skeleton and bobsledding. When practised on sand, it is known as a form of sandboarding. In Russia sledges are used for maritime activities including fishing and commuting from island to island on ice. History The practical use of sleds is ancient and widespread. They were developed in areas with consistent winter snow cover, as vehicles to transport materials and/or people, far more efficiently than wheeled vehicles could in icy and snowy conditions. Early designs included hand-pulled sizes as well as larger dog, horse, or ox drawn versions. Early examples of sleds and sledges were found in the Oseberg Viking ship excavation. The Toboggan sled is also a traditional form of transport used by the Innu and Cree of northern Canada and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cart
A cart or dray (Australia and New Zealand) is a vehicle designed for transport, using two wheels and normally pulled by one or a pair of draught animals. A handcart is pulled or pushed by one or more people. It is different from the flatbed trolley also known as a dray, (for freight) or wagon, which is a heavy transport vehicle with four wheels and typically two or more humans. Over time, the term "cart" has come to mean nearly any small conveyance, including shopping carts, golf carts, gokarts, and UTVs, without regard to number of wheels, load carried, or means of propulsion. The draught animals used for carts may be horses, donkeys or mules, oxen, and even smaller animals such as goats or large dogs. History Carts have been mentioned in literature as far back as the second millennium B.C. Handcarts pushed by humans have been used around the world. In the 19th century, for instance, some Mormons traveling across the plains of the United States between 1856 and 1860 use ...

Engineering Skeleton Sled
Engineering is the use of scientific method, scientific principles to design and build machines, structures, and other items, including bridges, tunnels, roads, vehicles, and buildings. The discipline of engineering encompasses a broad range of more specialized List of engineering branches, fields of engineering, each with a more specific emphasis on particular areas of applied mathematics, applied science, and types of application. See glossary of engineering. The term ''engineering'' is derived from the Latin ''ingenium'', meaning "cleverness" and ''ingeniare'', meaning "to contrive, devise". Definition The American Engineers' Council for Professional Development (ECPD, the predecessor of Accreditation Board for Engineering and Technology, ABET) has defined "engineering" as: The creative application of scientific principles to design or develop structures, machines, apparatus, or manufacturing processes, or works utilizing them singly or in combination; or to construct o ...

Extreme Sledding
Extreme sledding is a sport where riders do not simply sled down a hill, but use the sleds and their bodies to carry out various tricks, using apparatus such as ramps, rails, ledges, and some that are performed simply riding down the hill. The types of tricks that are carried out borrow certain characteristics from snowboarding, skateboarding, aggressive in-lining, BMXing, and motocross Motocross is a form of off-road motorcycle racing held on enclosed off-road circuits. The sport evolved from motorcycle trials competitions held in the United Kingdom. History Motocross first evolved in Britain from motorcycle trials competiti .... Extreme Sledding can use many different types of equipment, with the most common being "knee-sleds" which are sleds where you ride on your knees, (sometimes strapped on).

Samuel Leeds Allen
Samuel Leeds Allen (May 5, 1841 – March 28, 1918) was the founder of S.L. Allen & Company in Philadelphia. He was the inventor of, and his company manufactured, both the Flexible Flyer sled and Planet Jr farm and garden equipment. For over one hundred years these products were the best selling and most famous market gardening tools and American sleds. During his lifetime and for the first half of the 20th century S.L. Allen was far more renowned for his company's seed drills and cultivating equipment than the sleds. Biography Allen was born on May 5, 1841 in Philadelphia to Quaker parents: John Casdorp Allen, a prominent druggist, and Rebecca Smith Leeds, his wife. In 1861, Allen moved to ''Ivystone'', his father's farm near the community of Westfield in Cinnaminson Township, New Jersey. On November 22, 1866, Samuel Leeds Allen and Sarah Hooton Roberts, the daughter of Elisha Roberts and Elizabeth West Hooton, were married in the Friends Meeting House, Moorestown, New Jersey ...

Slope
In mathematics, the slope or gradient of a line is a number that describes both the ''direction'' and the ''steepness'' of the line. Slope is often denoted by the letter ''m''; there is no clear answer to the question why the letter ''m'' is used for slope, but its earliest use in English appears in O'Brien (1844) who wrote the equation of a straight line as and it can also be found in Todhunter (1888) who wrote it as "''y'' = ''mx'' + ''c''". Slope is calculated by finding the ratio of the "vertical change" to the "horizontal change" between (any) two distinct points on a line. Sometimes the ratio is expressed as a quotient ("rise over run"), giving the same number for every two distinct points on the same line. A line that is decreasing has a negative "rise". The line may be practical – as set by a road surveyor, or in a diagram that models a road or a roof either as a description or as a plan. The ''steepness'', incline, or grade of a line is measured by the absolute ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inner Tube
An inner tube is an inflatable ring that forms the interior of some pneumatic tires. The tube is inflated with a valve stem, and fits inside of the casing of the tire. The inflated inner tube provides structural support and suspension, while the outer tire provides grip and protects the more fragile tube. They are widely used in bicycles and are also used in many motorcycles and heavy road vehicles such as trucks and buses. They are now less common in other wheeled vehicles because of the benefits of having no tube, such as the ability to operate at low pressure and at high pressure (unlike a tube tire, which would pinch at low pressure and burst at high pressure), without going flat. Large inner rings also make effective flotation devices and are widely used in the leisure activity of tubing. Material The tube is made out of a mix of natural and synthetic rubber. Natural rubber is less prone to punctures and is often more pliable, while synthetic rubber is cheaper. Often racin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toboggan
A toboggan is a simple sled traditionally used by children. It is also a traditional form of transport used by the Innu and Cree of northern Canada. In modern times, it is used on snow to carry one or more people (often children) down a hill or other slope for recreation. Designs vary from simple, traditional models to modern engineered composites. A toboggan differs from most sleds or sleighs in that it has no runners or skis (or only low ones) on the underside. The bottom of a toboggan rides directly on the snow. Some parks include designated toboggan hills where ordinary sleds are not allowed and which may include toboggan runs similar to bobsleigh courses. Toboggans can vary depending on the climate and geographical region. Such examples are Tangalooma (Australia) where toboggans are made from Masonite boards and used for travelling down steep sand dunes at speeds up to . Design and use Before white colonists arrived in America, toboggan was a Native Indian term fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hill
A hill is a landform that extends above the surrounding terrain. It often has a distinct Summit (topography), summit. Terminology The distinction between a hill and a mountain is unclear and largely subjective, but a hill is universally considered to be not as tall, or as Grade (slope), steep as a mountain. Geographers historically regarded mountains as hills greater than above sea level, which formed the basis of the plot of the 1995 film ''The Englishman who Went up a Hill but Came down a Mountain''. In contrast, hillwalkers have tended to regard mountains as peaks above sea level. The ''Oxford English Dictionary'' also suggests a limit of and Whittow states "Some authorities regard eminences above as mountains, those below being referred to as hills." Today, a mountain is usually defined in the UK and Ireland as any summit at least high, while the official UK government's definition of a mountain is a summit of or higher.
