Screw-propelled Vehicle
A screw-propelled vehicle is a land or amphibious vehicle, amphibious vehicle designed to cope with difficult terrain, such as snow, ice, mud, and swamp. Such vehicles are distinguished by being moved by the rotation of one or more auger (drill), auger-like cylinders fitted with a helical flange that engages with the medium through or over which the vehicle is moving. They have been called Archimedes screw vehicles by the US military, where they are classified as a type of marginal terrain vehicle (MTV). Modern vehicles called Amphirols and other similar vehicles have specialised uses. The weight of the vehicle is typically borne by one or more pairs of large flanged cylinders; sometimes a single flanged cylinder is used with additional stabilising skis. These cylinders each have a Helix, helical spiral flange like the Screw thread, thread of a screw. On each matched pair of cylinders, one will have its flange running clockwise and the other counter-clockwise. The flange enga ...

Propeller
A propeller (often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft (ship), propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from stern sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the blade to the wat ...

Winter Road
A winter road is a seasonal road only usable during the winter, i.e. it has to be re-built every year. This road typically runs over land and over frozen lakes, rivers, swamps, and sea ice. Segments of a winter road that cross an expanse of floating ice are also referred to as an ice road or an ice bridge. The foundations underlying over-land segments is most often native soil or muskeg frozen to a given depth, and locally, bedrock. These surfaces may either be bare or are overlain, as is most commonly the case, with a snow cover. Over-ice segments of winter roads are often referred to as ice crossings, ice bridges or, simply, ice roads. The weight of the vehicle is supported by the buoyancy of the floating ice and by its resistance to flexure. Where a winter road is built mostly on floating ice, the occasional land crossings are called "portages" – the Tibbitt to Contwoyto Winter Road is an example. Winter roads facilitate transportation during the winter to, from and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Tahoe
Lake Tahoe (; Washo language, Washo: ''dáʔaw'') is a Fresh water, freshwater lake in the Sierra Nevada of the Western United States, straddling the border between California and Nevada.

Woodland, California
Woodland is a city in and the county seat of Yolo County, California, United States. Located approximately northwest of Sacramento, it is a part of the Sacramento metropolitan area. The population continues to grow every year, with a growth rate o0.33% annually, and a current population of 61,873. Woodland's origins date to 1850 when California gained statehood and Yolo County was established. The area was well irrigated due to the efforts of James Moore, which drew people into farming as the soil was very fertile. The city gained a federal post office in 1861 with the help of Missourian Frank S. Freeman. A year after thisin 1862 the county seat was moved from Washington (present day West Sacramento) to Woodland after Washington was flooded. The addition of a railroad line to Sacramento, and the more recent addition of Interstate 5, helped the city to thrive. History Indigenous culture Before its settlement by people of European descent, the Woodland area was inhabited by t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chevrolet
Chevrolet ( ) is an American automobile division of the manufacturer General Motors (GM). In North America, Chevrolet produces and sells a wide range of vehicles, from subcompact automobiles to medium-duty commercial trucks. Due to the prominence and name recognition of Chevrolet as one of General Motors' global marques, "Chevrolet" or its affectionate nickname 'Chevy' or is used at times as a synonym for General Motors or its products, one example being the GM LS1 engine, commonly known by the name or a variant thereof of its progenitor, the Chevrolet small-block engine. Louis Chevrolet (1878–1941), Arthur Chevrolet (1884–1946) and ousted General Motors founder William C. Durant (1861–1947) started the company on November 3, 1911 as the Chevrolet Motor Car Company.

After Durant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fordson Tractor
Fordson was a brand name of tractors and trucks. It was used on a range of mass-produced general-purpose tractors manufactured by Henry Ford & Son Inc from 1917 to 1920, by Ford Motor Company (U.S.) and Ford Motor Company Ltd (U.K.) from 1920 to 1928, and by Ford Motor Company Ltd (U.K.) alone from 1929 to 1964. The latter (Ford of Britain) also later built trucks and vans under the Fordson brand. After 1964, the Fordson name was dropped and all Ford tractors were simply badged as Fords in both the UK and the US. Production years Between 1917 and 1922, the Fordson design for tractors was somewhat like the Ford Model T was for automobiles—it captured the public's imagination and widely popularized the machine, with a reliable design, a low price affordable for workers and farmers, a widespread dealership network, and a production capacity for large numbers. Just as the Ford Model T helped the public to appreciate how soon cars and trucks might replace most horses in transpor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Caterpillar Tracks
Continuous track or tracked treads are a system of vehicle propulsion used in tracked vehicles, running on a continuous band of treads or track plates driven by two or more wheels. The large surface area of the tracks distributes the weight of the vehicle better than steel or rubber tyres on an equivalent vehicle, enabling continuous tracked vehicles to traverse soft ground with less likelihood of becoming stuck due to sinking. Modern continuous tracks can be made with soft belts of synthetic rubber, reinforced with steel wires, in the case of lighter agricultural machinery. The more common classical type is a solid chain track made of steel plates (with or without rubber pads), also called caterpillar tread or tank tread, which is preferred for robust and heavy construction vehicles and military vehicles. The prominent treads of the metal plates are both hard-wearing and damage resistant, especially in comparison to rubber tyres. The aggressive treads of the tra ...
