Auto racing
–
Auto racing is a sport involving the racing of automobiles for competition. Almost as soon as automobiles had been invented, races of various sorts were organised, by the 1930s specialist racing cars had developed. There are now numerous different categories, each with different rules and it was won by the carriage of Isaac Watt Boulton. Internal combustion auto racing events began soon after the construction of the first successful gasoline-fueled automobiles, the first organized contest was on April 28,1887, by the chief editor of Paris publication Le Vélocipède, Monsieur Fossier. It ran 2 kilometres from Neuilly Bridge to the Bois de Boulogne, on July 22,1894, the Parisian magazine Le Petit Journal organized what is considered to be the worlds first motoring competition, from Paris to Rouen. One hundred and two competitors paid a 10-franc entrance fee, the first American automobile race is generally held to be the Thanksgiving Day Chicago Times-Herald race of November 28,1895. Press coverage of the event first aroused significant American interest in the automobile, brooklands, in Surrey, was the first purpose-built motor racing venue, opening in June 1907. It featured a 4.43 km concrete track with high-speed banked corners, One of the oldest existing purpose-built automobile racing circuits in the United States, still in use, is the 2. 5-mile -long Indianapolis Motor Speedway in Speedway, Indiana. It is the largest capacity venue of any variety worldwide, with a top capacity of some 257. NASCAR was founded by Bill France, Sr. on February 21,1948, the first NASCAR Strictly Stock race ever was held on June 19,1949, at Daytona Beach, Florida. From 1962, sports cars temporarily took a seat to GT cars. From 1972 through 2003, NASCARs premier series was called the Winston Cup Series, the changes that resulted from RJRs involvement, as well as the reduction of the schedule from 48 to 31 races a year, established 1972 as the beginning of NASCARs modern era. The IMSA GT Series evolved into the American Le Mans Series, the European races eventually became the closely related Le Mans Series, both of which mix prototypes and GTs. The best-known variety of racing, Formula One, which hosts the famous Monaco Grand Prix. In single-seater, the wheels are not covered, and the cars often have aerofoil wings front, in Europe and Asia, open-wheeled racing is commonly referred to as Formula, with appropriate hierarchical suffixes. In North America, the Formula terminology is not followed, the sport is usually arranged to follow an international format, a regional format, and/or a domestic, or country-specific, format. In North America, the used in the National Championship have traditionally been similar though less sophisticated than F1 cars. The series most famous race is the Indianapolis 500, the other major international single-seater racing series is GP2

Formula One
–
Formula One is the highest class of single-seat auto racing that is sanctioned by the Fédération Internationale de lAutomobile. The FIA Formula One World Championship has been the form of racing since the inaugural season in 1950. The formula, designated in the name, refers to a set of rules, the F1 season consists of a series of races, known as Grands Prix, held worldwide on purpose-built F1 circuits and public roads. The results of each race are evaluated using a system to determine two annual World Championships, one for drivers, one for constructors. The racing drivers are required to be holders of valid Super Licences, the races are required to be held on tracks graded 1, the highest grade a track can receive by the FIA. Most events are held in locations on purpose-built tracks, but there are several events in city centres throughout the world. Formula One cars are the fastest road racing cars in the world. Formula One cars race at speeds of up to approximately 375 km/h with engines currently limited in performance to a maximum of 15,000 RPM, the cars are capable of lateral acceleration in excess of five g in corners. The performance of the cars is very dependent on electronics – although traction control and other driving aids have been banned since 2008 – and on aerodynamics, suspension, the formula has radically evolved and changed through the history of the sport. F1 had a global television audience of 425 million people during the course of the 2014 season. Grand Prix racing began in 1906 and became the most popular internationally in the second half of the twentieth century. The Formula One Group is the holder of the commercial rights. Its high profile and popularity have created a major merchandising environment, since 2000 the sports spiraling expenditures and the distribution of prize money favoring established top teams have forced complaints from smaller teams and led several teams to bankruptcy. On 23 January 2017 it was confirmed that Liberty Media had completed its $8 billion acquisition of Delta Topco, the Formula One series originated with the European Grand Prix Motor Racing of the 1920s and 1930s. The formula is a set of rules that all cars must meet. Formula One was a new formula agreed upon after World War II during 1946, the first world championship race was held at Silverstone, United Kingdom in 1950. A championship for constructors followed in 1958, national championships existed in South Africa and the UK in the 1960s and 1970s. Non-championship Formula One events were held for years, but due to the increasing cost of competition

Alfa Romeo (Formula One)
–
Alfa Romeo participated in Formula One, as both a constructor and engine supplier, from 1950 to 1988. Alfa Romeo had often been a force in Grand Prix racing before World War II, from 1934 to the start of World War II in 1939, Alfa rarely won and their cars looked rather outdated and badly built compared to the high-tech Silver Arrows. When the new Formula One World Championship had come around, Alfa had absolutely dominated post-WWII racing from 1946 to 1949- winning every Grand Prix they entered with the exception of 3. In 1950 Nino Farina won the inaugural World Championship of Drivers in a 158 with supercharger, in 1951 Juan Manuel Fangio won while driving an Alfetta 159. The Alfettas engines were powerful for their capacity, in 1951 the 159 engine was producing around 420 bhp. Surprisingly, Alfa Romeo involvement in racing was made with a thin budget, using mostly pre-war technology. For instance the team won two championships using only nine pre-war built engine blocks, during the 1960s, several minor F1 teams used Alfa Romeo straight-4 engines in cars such as the LDS Mk1 and Mk2 Specials, Coopers and De Tomasos. In the end of 1960s Alfa Romeo was developing a new V8 engine for its racing cars, Alfa Romeo briefly returned to Formula One for the 1970 and 1971 seasons with a V8 engine based on their sportscar unit. In 1970 the unit was entrusted to Andrea de Adamich. The combination often failed to qualify and was uncompetitive when it did run in the races, in 1971 a similar arrangement saw de Adamich run most of the second half of the season in a works March car, with a similar lack of success. For 1976 Bernie Ecclestone did a deal for the Brabham Formula One team to use Alfa Romeo engines based on their new sports car unit. At Murrays instigation Alfa produced a narrower V12 design in three months for the 1979 season, but it continued to be unreliable and fuel inefficient. During 1977, and after persuasion by Chiti, Alfa Romeo gave Autodelta permission to start developing a Formula One car on their behalf. Thus named the Alfa Romeo 177, the car made its debut at the 1979 Belgian Grand Prix, the partnership with Brabham had finished before the end of the season, with Bernie Ecclestones outfit returning to Ford/Cosworth DFV engines. This second Alfa works Formula One project was never truly successful during its existence from the middle of 1979 until the end of 1985 and they also endured tragedy when their driver Patrick Depailler was killed testing for the 1980 German Grand Prix at the Hockenheimring. In 1981 they had the services of Mario Andretti, but continued to be dogged by poor reliability, after a restructuring of Autodelta, the team operations and design of the car were outsourced to Euroracing in 1982, with the works engines still being supplied by Autodelta. The 890T was very thirsty and suffered badly at fast circuits- particularly both of Alfas home circuits of Imola and Monza, the engine was developed but the fuel consumption problems were never really rectified. The teams 1985 car, the Alfa Romeo 185T proved to be so uncompetitive that the 1984 car, after being updated to 1985 specifications the car, now dubbed the 184TB, was actually an improvement over the 1985 car, but results were still not forthcoming

Automotive design
–
Automotive design is the profession involved in the development of the appearance, and to some extent the ergonomics, of motor vehicles or more specifically road vehicles. This most commonly refers to automobiles but also refers to motorcycles, trucks, buses, coaches, the functional design and development of a modern motor vehicle is typically done by a large team from many different disciplines included within automotive engineering. Automotive design in context is primarily concerned with developing the visual appearance or aesthetics of the vehicle. Automotive design is practiced by designers who usually have an art background, the task of the design team is usually split into three main aspects, exterior design, interior design, and color and trim design. Graphic design is also an aspect of design, this is generally shared amongst the design team as the lead designer sees fit. Design focuses not only on the outer shape of automobile parts. The aesthetic value will need to correspond to ergonomic functionality and utility features as well, though not all the new vehicular gadgets are to be designated as factory standard items, some of them may be integral to determining the future course of any specific vehicular models. The stylist responsible for the design of the exterior of the vehicle develops the proportions, shape, Exterior design is first done by a series of digital or manual drawings. Progressively, drawings that are more detailed are executed and approved by appropriate layers of management, Clay and or digital models are developed from, and along with the drawings. The data from these models are used to create a full sized mock-up of the final design. With three- and five-axis CNC milling machines, the model is first designed in a computer program and then carved using the machine. Even in times of high-class 3d software and virtual models on power walls, here the emphasis is on ergonomics and the comfort of the passengers. The procedure here is the same as with exterior design, the color and trim designer is responsible for the research, design, and development of all interior and exterior colors and materials used on a vehicle. These include paints, plastics, fabric designs, leather, grains, carpet, headliner, wood trim, Color, contrast, texture, and pattern must be carefully combined to give the vehicle a unique interior environment experience. Designers work closely with the exterior and interior designers, designers draw inspiration from other design disciplines such as, industrial design, fashion, home furnishing, architecture, and sometimes product design. Specific research is done into global trends to design for two to three model years in the future. Trend boards are created from research in order to keep track of design influences as they relate to the automotive industry. The designer then uses this information to develop themes and concepts that are further refined and tested on the vehicle models

Chassis
–
A chassis consists of an internal vehicle frame that supports an artificial object in its construction and use, can also provide protection for some internal parts. An example of a chassis is the underpart of a motor vehicle, if the running gear such as wheels and transmission, and sometimes even the drivers seat, are included, then the assembly is described as a rolling chassis. In the case of vehicles, the rolling chassis means the frame plus the running gear like engine, transmission, drive shaft, differential. An under body, which is not necessary for integrity of the structure, is built on the chassis to complete the vehicle. For commercial vehicles, a rolling chassis consists of an assembly of all the parts of a truck to be ready for operation on the road. The design of a car chassis will be different than one for commercial vehicles because of the heavier loads. Commercial vehicle manufacturers sell chassis only, cowl and chassis, as well as chassis cab versions that can be outfitted with specialized bodies and these include motor homes, fire engines, ambulances, box trucks, etc. In particular applications, such as buses, a government agency like National Highway Traffic Safety Administration in the U. S. defines the design standards of chassis. An armoured fighting vehicles hull serves as the chassis and comprises the part of the AFV that includes the tracks, engine, drivers seat. This describes the hull, although common usage might include the upper hull to mean the AFV without the turret. The hull serves as a basis for platforms on tanks, armoured carriers, combat engineering vehicles. In an electronic device, the chassis consists of a frame or other supporting structure on which the circuit boards. In the absence of a frame, the chassis refers to the circuit boards and components themselves. The combination of chassis and outer covering is called an enclosure.

Carbon fiber reinforced polymer
–
Carbon fiber reinforced polymer, carbon fiber reinforced plastic or carbon fiber reinforced thermoplastic, is an extremely strong and light fiber-reinforced plastic which contains carbon fibers. The spelling fibre is common in British Commonwealth countries, the binding polymer is often a thermoset resin such as epoxy, but other thermoset or thermoplastic polymers, such as polyester, vinyl ester or nylon, are sometimes used. The composite may contain other fibers, such as an aramid, aluminium, ultra-high-molecular-weight polyethylene or glass fibers, the properties of the final CFRP product can also be affected by the type of additives introduced to the binding matrix. The most frequent additive is silica, but other such as rubber. The material is referred to as graphite-reinforced polymer or graphite fiber-reinforced polymer. In product advertisements, it is referred to simply as graphite fiber for short. In this case the composite consists of two parts, a matrix and a reinforcement, in CFRP the reinforcement is carbon fiber, which provides the strength. The matrix is usually a resin, such as epoxy. Because CFRP consists of two elements, the material properties depend on these two elements. The reinforcement will give the CFRP its strength and rigidity, measured by stress, unlike isotropic materials like steel and aluminum, CFRP has directional strength properties. The properties of CFRP depend on the layouts of the carbon fiber, the following equation, E c = V m E m + V f E f is valid for composite materials with the fibers oriented in the direction of the applied load. Typical epoxy-based CFRPs exhibit virtually no plasticity, with less than 0. 5% strain to failure, although CFRPs with epoxy have high strength and elastic modulus, the brittle fracture mechanics present unique challenges to engineers in failure detection since failure occurs catastrophically. As such, recent efforts to toughen CFRPs include modifying the existing epoxy material, One such material with high promise is PEEK, which exhibits an order of magnitude greater toughness with similar elastic modulus and tensile strength. However, PEEK is much more difficult to process and more expensive, despite its high initial strength-to-weight ratio, a design limitation of CFRP is its lack of a definable fatigue endurance limit. This means, theoretically, that stress cycle failure cannot be ruled out, environmental effects such as temperature and humidity can have profound effects on the polymer-based composites, including most CFRPs. While the carbon fibers themselves are not affected by the moisture diffusing into the material, the carbon fibers can cause galvanic corrosion when CRP parts are attached to aluminum. The primary element of CFRP is a filament, this is produced from a precursor polymer such as polyacrylonitrile, rayon. Precursor compositions and mechanical processes used during spinning filament yarns may vary among manufacturers, after drawing or spinning, the polymer filament yarns are then heated to drive off non-carbon atoms, producing the final carbon fiber

Monocoque
–
Monocoque, also structural skin, is a structural system where loads are supported through an objects external skin, similar to an egg shell. The word monocoque is a French term for single shell or single hull, a true monocoque carries both tensile and compressive forces within the skin and can be recognised by the absence of a load carrying internal frame. By contrast, a semi-monocoque is a combining a tensile stressed skin. Other semi-monocoques not to be confused with true monocoques include vehicle unibodies, which tend to be composites, early aircraft were constructed using frames, typically of wood or steel tubing, which could then be covered with fabric such as irish linen or cotton. The skin added nothing to the strength of the airframe and was dead weight beyond providing a smooth sealed surface. This reduced drag so effectively it was able to win most of the races it was entered into, however, it was prone to damage from moisture and delamination. While all metal aircraft from the Junkers firm had appeared as early as 1915, the first metal monocoques were built by Claudius Dornier, while working for Zeppelin-Lindau. After failed attempts with several large flying boats in which a few components were monocoques, the aluminum alloy monocoque chassis was first used in the 1962 Lotus 25 Formula 1 race car. The term monocoque is frequently misused when referring to unibody cars, in motor racing, the safety of the driver depends on the car body which must meet stringent regulations and a few cars have been built with monocoque structures. Tanks and other armored vehicles such as the German Fuchs 2 and this reduces weight for a given amount of armor compared to vehicles to which armor has been attached to an underlying frame. A monocoque-framed motorcycle was developed by the Spanish motorcycle manufacturer, Ossa, Ossa won four Grand Prix races with the monocoque bike before their rider was killed during the 1970 Isle of Man TT, causing the Ossa factory to withdraw from Grand Prix competition. Notable designers such as Eric Offenstadt and Dan Hanebrink created unique monocoque designs in the early 1970s, the 1973 Isle of Man TT was won by Peter Williams on the monocoque-framed Norton John Player Special that he helped design. Honda also experimented with a monocoque Grand Prix racing motorcycle named the NR500 in 1979, in 1987 John Britten developed the Aero-D One, featuring a composite monocoque chassis that weighed only 12 kg. The first time an aluminium monocoque frame appeared on a production motorcycle was the 2000 Kawasaki Ninja ZX-12R. This was Kawasakis flagship production sportbike aimed at being the fastest production motorcycle, various rockets have used pressure-stabilized monocoque designs, such as Atlas and Falcon 1. Balloon tanks are not true monocoques but act in the way as inflatable shells. A balloon tank skin only handles tensile forces while compression is resisted by internal pressure in a way similar to semi-monocoques braced by a solid frame. This becomes obvious when internal pressure is lost and the structure collapses, the Handle is an electric guitar characterized by its hollow sectioned monocoque chassis, created by the award-winning designer Peter Solomon

Wheelbase
–
In both road and rail vehicles, the wheelbase is the distance between the centers of the front and rear wheels. For road vehicles with more than two axles, the wheelbase is defined as the distance between the axle and the centerpoint of the driving axle group. In the case of a truck, the wheelbase would be the distance between the steering axle and a point midway between the two rear axles. The wheelbase of a vehicle equals the distance between its front and rear wheels, at equilibrium, the total torque of the forces acting on a vehicle is zero. So, for example, when a truck is loaded, its center of gravity shifts rearward, the amount the vehicle sinks will depend on counter acting forces like the size of the tires, tire pressure, and the stiffness of the suspension. If the vehicle is accelerating or decelerating, extra torque is placed on the rear or front tire respectively, so, as is common experience, when the vehicle accelerates, the rear usually sinks and the front rises depending on the suspension. Likewise, when braking the front noses down and the rear rises, because of the effect the wheelbase has on the weight distribution of the vehicle, wheelbase dimensions are crucial to the balance and steering. For example, a car with a greater weight load on the rear tends to understeer due to the lack of the load on the front tires. This is why it is crucial, when towing a single-axle caravan, likewise, a car may oversteer or even spin out if there is too much force on the front tires and not enough on the rear tires. Also, when turning there is lateral torque placed upon the tires which imparts a turning force that depends upon the length of the distances from the CM. Wheelbases provide the basis for one of the most common vehicle size class systems, some luxury vehicles are offered with long-wheelbase variants to increase the spaciousness and therefore the luxury of the vehicle. Prime Minister of the United Kingdom Tony Blair was given a version of the Rover 75 for official use. In contrast, coupé varieties of vehicles such as the Honda Accord are usually built on shorter wheelbases than the sedans they are derived from. The wheelbase on many commercially available bicycles and motorcycles is so short, relative to the height of their centers of mass, in skateboarding the word wheelbase is used for the distance between the two inner pairs of mounting holes on the deck. This is different from the distance between the centers of the two wheel pairs. A reason for this use is that decks are sold with prefabricated holes. It is therefore easier to use the holes for measuring and describing this characteristic of the deck. A common misconception is that the choice of wheelbase is influenced by the height of the skateboarder, however, the length of the deck would then be a better candidate, because the wheelbase affects characteristics useful in different speeds or terrains regardless of the height of the skateboarder
