Pacenotes
In rallying, pacenotes are a commonly used method of accurately describing a rallying route to be driven in extreme detail. As well as dictating the general route to be taken, in terms of turnings, junctions, etc., all notable features of the route which might affect the way it is driven at speed are included. These details include the distance between each feature, the degree and severity of bends, adverse camber, crests and hill jumpings, surface type and conditions, potholes, special instructions to the driver, etc. In order that the sheer quantity of detail is useful to a rally team, pacenotes are written in a tight shorthand which is read out loud by the navigator (usually called "co-driver") to the driver en route. A number of systems have been devised, and there is no one "standard" for pacenotes, but in practice a number of typical de facto standards are usually used. Other variations include the preferred language of the team, metric or imperial measurements, etc. Pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rallying
Rallying is a wide-ranging form of motorsport with various competitive motoring elements such as speed tests (sometimes called "rally racing" in United States), navigation tests, or the ability to reach waypoints or a destination at a prescribed time or average speed. Rallies may be short in the form of trials at a single venue, or several thousand miles long in an extreme endurance rally. Depending on the format, rallies may be organised on private or public roads, open or closed to traffic, or off-road in the form of cross country or rally-raid. Competitors can use Production vehicle, production vehicles which must be Street-legal vehicle, road-legal if being used on open roads or specially built competition vehicles suited to crossing specific terrain. In most cases rallying distinguishes itself from other forms of motorsport by not running directly against other competitors over laps of a Race track, circuit, but instead in a point-to-point format in which participants leave ...

Co-driver
A co-driver is the navigator of a rally car in the sport of rallying, who sits in the front passenger seat. The co-driver's job is to navigate, commonly by reading off a set of pacenotes to the driver (what lies ahead, where to turn, the severity of the turn, and what obstacles to look out for). Some competitions require map interpretation. In stage rallying communication is often over a radio headset, due to the high level of noise in the car. The co-driver also tells the driver about any incidents or accidents that may have occurred further ahead in the stage. , motorsportads.com, no date This role is particularly critical in high-end rally competitions such as [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cant (road/rail)
The cant of a Rail transport, railway track or camber angle, camber of a road (also referred to as superelevation, cross slope or cross fall) is the rate of change in elevation (height) between the two rails or edges of the road. This is normally greater where the railway or road is curved; raising the outer rail or the outer edge of the road creates a banked turn, thus allowing vehicles to travel round the curve at greater speeds than would be possible if the surface were level. Rail Superelevation in railway tracks ;Importance of superelevation In curved railway tracks, the outer rail is elevated, providing a banked turn. This allows trains to navigate curves at higher speeds and reduces the pressure of the wheel flanges against the rails, minimizing friction and wear. The difference in elevation between the outer and inner rails is referred to as cant in most countries. ;How superelevation works The main functions of cant are the following: * Improve distribution of th ...

Hill Jumping
Hill jumping is the act of accelerating a rally vehicle as it approaches the top of a hill, causing the vehicle to go airborne. The activity is also called "hill topping" and "yumping". Hill jumping may take place at formal rally racing Rally or rallye may refer to: Gatherings * Political demonstration, a political rally, a political demonstration of support or protest, march, or parade * Pep rally, an event held at a North American school or college sporting event Sports ... events. Or, at substantial risk to the health and safety of participants and third parties, it may take place on public roads at informal gatherings or by thrill seeking individuals. Hill jumping can also be performed on skateboards, it can take place on roads, trails, or even ramps. Depending on the height of the hill, it can result in injury or death.

Shorthand
Shorthand is an abbreviated symbolic writing method that increases speed and brevity of writing as compared to Cursive, longhand, a more common method of writing a language. The process of writing in shorthand is called stenography, from the Greek language, Greek ''stenos'' (narrow) and ''graphein'' (to write). It has also been called brachygraphy, from Greek ''brachys'' (short), and tachygraphy, from Greek ''tachys'' (swift, speedy), depending on whether compression or speed of writing is the goal. Many forms of shorthand exist. A typical shorthand system provides symbols or abbreviations for words and common phrases, which can allow someone well-trained in the system to write as quickly as people speak. Abbreviation methods are alphabet-based and use different abbreviating approaches. Many journalists use shorthand writing to quickly take notes at press conferences or other similar scenarios. In the computerized world, several autocomplete programs, standalone or integrated in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Odometer
An odometer or odograph is an instrument used for measuring the distance traveled by a vehicle, such as a bicycle or car. The device may be electronic, mechanical, or a combination of the two (electromechanical). The noun derives from ancient Greek , ''hodómetron'', from , ''hodós'' ("path" or "gateway") and , ''métron'' ("measure"). Early forms of the odometer existed in the ancient Greco-Roman world as well as in ancient China. In countries using Imperial units or US customary units it is sometimes called a mileometer or milometer, the former name especially being prevalent in the United Kingdom and among members of the Commonwealth of Nations, Commonwealth. History Classical Era Possibly the first evidence for the use of an odometer can be found in the works of the ancient Roman Pliny the Elder, Pliny (NH 6. 61-62) and the ancient Greek Strabo (11.8.9). Both authors list the distances of routes traveled by Alexander the Great (r. 336-323 BC) as by his bematists Diog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
