Upholstery
Upholstery is the work of providing furniture, especially seats, with padding, springs, webbing, and fabric or leather covers. The word "upholstery" comes from the Middle English word "upholder", which referred to a tradesman who held up his goods. The term is equally applicable to domestic, automobile, airplane and boat furniture, and can be applied to mattresses, particularly the upper layers, though these often differ significantly in design. A person who works with upholstery is called an upholsterer; an apprentice upholsterer is sometimes called an outsider or trimmer. Traditional upholstery uses materials like coil springs (post-1850), animal hair (horse, hog and cow), coir, straw and hay, hessians, linen scrims, wadding, etc., and is done by hand, building each layer up.
Oldsmobile 98
The Oldsmobile 98 (sometimes spelled Ninety-Eight after 1958) is the full-size flagship model of Oldsmobile that was produced from 1940 until 1996. The name — reflecting a "Series 90" fitted with an 8-cylinder engine — first appeared in 1941 and was used again after American consumer automobile production resumed post-World War II. It was, as it would remain, the division's top-of-the-line model, with lesser Oldsmobiles having lower numbers such as the A-body 66 and 68, and the B-body 76 and 78. The Series 60 was retired in 1949, the same year the Oldsmobile 78 was replaced by the 88. The Oldsmobile 76 was retired after 1950.
Valeria Miani
Valeria Miani (1563 – 1620) was a female playwright noted for her works Celina, a Tragedy, and Amorosa Speranza. Miani married Domenico Negri in 1593, with whom she had five children, Isabetta, Isabella, Lucretia, Guilio, and Anzolo. Miani is known for being the first woman to publish a tragedy prior to the 18th century. In addition, she was the third woman in Italy to write in the newly popular genre, the pastoral. Miani's works explored themes such as cross-dressing, death and punishment, female virtue, and female resilience. Miani was born in the year 1563, most likely in the northern Italian city of Padua.
Bookbinding
Bookbinding is the process of physically assembling a book from an ordered stack of paper sheets that are folded together into sections or sometimes left as a stack of individual sheets. The stack is then bound together along one edge by either sewing with thread through the folds or by a layer of flexible adhesive. Alternative methods of binding that are cheaper but less permanent include loose-leaf rings, individual screw posts or binding posts, twin loop spine coils, plastic spiral coils, and plastic spine combs. For protection, the bound stack is either wrapped in a flexible cover or attached to stiff boards.
Subaru Legacy (first generation)
The first generation Subaru Legacy is a mid-size family car / wagon developed by Fuji Heavy Industries. The Legacy was an all new model, and was considered a notable departure from Subaru products in the past. The worldwide introduction of the Legacy sedan and wagon was achieved in 1989. The earlier sedan and wagon are becoming more rare and collectables especially the earlier wagons. Subaru had earned a reputation of building vehicles that were regarded as "quirky" while other Asian manufacturers were bringing more upscale and conventional appearing models to the market. The Legacy was different and became a solid production that changed Subaru's reputation.
Rolls-Royce Phantom (2003)
The Rolls-Royce Phantom VII was a luxury saloon car made by Rolls-Royce Motor Cars. Launched in 2003, it was the first Rolls-Royce developed and introduced after BMW purchased the right to use the Rolls-Royce name and logo in 1998. It is credited with successfully reviving the Rolls-Royce brand and restoring Rolls-Royce's credibility as a maker of luxury cars. The Phantom Drophead Coupé and Phantom Coupé are two-door derivatives of the Phantom launched in 2007 and 2008, respectively. From 2003 until the launch of the smaller Ghost in 2009, the Phantom was the only car produced by Rolls-Royce. The Phantom acted as the company's flagship model.
Mercedes-Benz SLS AMG
The Mercedes-Benz SLS AMG (C197 / R197) is a front mid-engine, 2-seater luxury, limited production supercar automobile developed by Mercedes-AMG of German automaker Mercedes-Benz and was the first Mercedes-Benz automobile designed in-house by AMG. The car, which has gull-wing doors, was the successor to the Mercedes-Benz SLR McLaren and was described by Mercedes-Benz as a spiritual successor to the Mercedes-Benz 300SL Gullwing. SLS stands for "Super Leicht Sport" (Super Light Sport). The Mercedes-Benz SLS AMG was assembled largely by hand, with its chassis and aluminum body shell produced by Magna Steyr in Graz, Austria and then transferred to Sindelfingen, Germany for assembly, with its engine being hand built by AMG in Affalterbach, Germany.

Oldsmobile 88
The Oldsmobile 88 (known from 1989 onwards as the Eighty Eight) is a full-size car that was sold and produced by Oldsmobile from 1949 until 1999. From 1950 to 1974 the 88 was the division's top-selling line, particularly the entry-level models such as the 88 and Dynamic 88. The 88 series was also an image leader for Oldsmobile, particularly in the early years (1949–51) when it was one of the best performing automobiles thanks to its relatively small size, light weight and advanced overhead-valve high-compression V8 engine. This engine, originally designed for the larger C-bodied and more luxurious 98 series, also replaced the straight-8 on the smaller B-bodied 78.
Oldsmobile V8 engine
The Oldsmobile V8 refers to a series of Oldsmobile engines beginning with the advanced 1949 Rocket which were, along with the 1949 Cadillac V8, the first post-war OHV V8 engines produced by General Motors. Like all other GM divisions, Olds continued building its own V8 engine family for decades, finally adopting the corporate Chevrolet 350 small-block and Cadillac Northstar engine only in the 1990s. All Oldsmobile V8s were manufactured at plants in Lansing, Michigan. All Oldsmobile V8s use a 90° bank angle, and most share a common stroke dimension: for early Rockets, for later Generation 1 engines, and for Generation 2 starting in 1964.
Oldsmobile Aurora
The Oldsmobile Aurora is a mid-size luxury sports sedan made by Oldsmobile from 1994 to 2003. The Aurora rides on the same Cadillac-derived G platform as the two-door Buick Riviera. The Aurora became the high-end sport sedan Oldsmobile, powered by a four-cam, 32-valve 4.0 L V8 supplanting the Oldsmobile Toronado coupe and eventually the Oldsmobile 98, in the lineup. The Aurora offered both a V8- and a V6-powered version in 2001 and 2002 but returned to being V8-only in 2003. It is equipped with a four-speed automatic transmission with performance algorithm shifting. No manual transmission was ever offered on the Aurora.
Oldsmobile
Oldsmobile was a brand of American automobiles produced for most of its existence by General Motors. Olds Motor Vehicle Co. was founded by Ransom E. Olds in 1897. It produced over 35 million vehicles, including at least 14 million built at its Lansing, Michigan factory. At the time of its closure, Oldsmobile was the oldest surviving American automobile marque, and one of the oldest in the world, after Daimler, Peugeot and Tatra. Oldsmobiles were first manufactured by the Olds Motor Vehicle Co. in Lansing, Michigan, a company founded by Ransom E. Olds in 1897. In 1901, the company produced 635 cars, making it the first high-volume gasoline-powered automobile manufacturer.
Buick Electra
The Buick Electra is a full-size luxury car that was built by Buick from 1959 to 1990. Harlow H. Curtice, former president of the Buick division and later president of General Motors, named the car after his sister-in-law, Electra Waggoner Biggs. During its more than 30-year run, Electra was offered in varying body styles including coupe, convertible, sedan, and station wagon. The Electra was replaced by the Buick Park Avenue in 1991. For years, the Super and the Roadmaster constituted the upper echelon of Buick's lineup. The Limited, even more luxurious than the Roadmaster, returned for 1958. For 1959, the former two were renamed the Electra and the Electra 225 respectively, and the last was discontinued for being unsuccessful.
Oldsmobile Starfire
The Oldsmobile Starfire is an automobile nameplate used by Oldsmobile, produced in three non-contiguous generations beginning in 1954. The Starfire nameplate made its debut with the 1954–1956 Ninety- Eight series convertibles. By 1957 all Ninety-Eight series models were Starfires..  After a two-year hiatus a single convertible body style Starfire became available in 1961. Intended to compete in the growing personal luxury car market, it shared most of its sheet metal with other models and was considered part of the full-sized Oldsmobile line. The Starfire Hardtop Coupe joined the convertible for the 1962 model year.

Straight-five engine
The straight-five engine or inline-five engine is an internal combustion engine with five cylinders aligned in one row or plane, sharing a single engine block and crankcase. The justification for a five cylinder engine is that it is almost as compact as an inline-four, and almost as smooth as a straight-six engine. A variation of the inline-five is the narrow-angle V5 (such as the Volkswagen V5 engine) which has a single cylinder-head and cylinder-block, and which is very compact. Henry Ford had an inline-five engine developed in the late 1930s to early 1940s for a compact economy car design, which never saw production due to lack of demand for small cars in the United States.
Cosworth
Cosworth is an automotive engineering company founded in London in , specialising in high-performance internal combustion engines, powertrain, and electronics; for automobile racing (motorsport) and mainstream automotive industries. Cosworth is based in Northampton, England, with North American facilities in Indianapolis and Mooresville, North Carolina. Cosworth has collected 176 wins in Formula One (F1) as engine supplier, ranking second with most wins behind Ferrari. The company was founded as a British racing internal combustion engine maker in 1958 by Mike Costin and Keith Duckworth. Its company name: 'Cosworth', was derived as a portmanteau of the surnames of its two founders (COStin and duckWORTH).
Coventry Climax
Coventry Climax was a British forklift truck, fire pump, racing, and other speciality engine manufacturer. The company was started in 1903 as Lee Stroyer, but two years later, following the departure of Stroyer, it was relocated to Paynes Lane, Coventry, and renamed as Coventry-Simplex by H. Pelham Lee, a former Daimler employee, who saw a need for competition in the nascent piston engine market. An early user was GWK, who produced over 1,000 light cars with Coventry-Simplex two-cylinder engines between 1911 and 1915. Just before World War I a Coventry-Simplex engine was used by Lionel Martin to power the first Aston Martin car.
V6 engine
A V6 engine is a V engine with six cylinders mounted on the crankshaft in two banks of three cylinders, usually set at either a 60 or 90 degree angle to each other. The V6 is one of the most compact engine configurations, usually ranging from 2.0 L to 4.3 L displacement (however, much larger examples have been produced for use in trucks), shorter than the inline 4 and more compact than the V8 engine. Because of its short length, the V6 fits well in the widely used transverse engine front-wheel drive layout. The V6 is commercially successful in mid-size cars in the modern age of high fuel prices and price sensitive consumers because it is less expensive to build and has better fuel consumption than the V8, while being smoother in large sizes than the inline 4, which develops increasingly serious vibration problems in larger engines.
Engine balance
Engine balance refers to those factors in the design, production, engine tuning, maintenance and the operation of an engine that benefit from being balanced. Major considerations are:  This article is currently limited to structural and operational balance within an engine in general, and balancing of piston engine components in particular. Piston engine balancing is a complicated subject that covers many areas in the design, production, tuning and operation. The engine considered to be well balanced in a particular usage may produce unacceptable level of vibration in another usage for the difference in driven mass and mounting method, and slight variations in resonant frequencies of the environment and engine parts could be big factors in throwing a smooth operation off balance.
Economy car
An economy car is an automobile that is designed for low-cost purchase and operation. Typical economy cars are small (compact or subcompact), lightweight, and inexpensive to buy. Economy car designers are forced by stringent design constraints to be inventive. Many innovations in automobile design were originally developed for economy cars, such as the Ford Model T and the Austin Mini. Gordon Murray, the Formula 1 and Mclaren F1 designer, said when designing his new Murray T.25 city car: "I would say that building a car to sell for six thousand pounds and designing that for a high-volume production, where you have all the quality issues under control, is a hundred times more difficult than designing a Mclaren F1, or even a racing car.
Seekonk Speedway
Seekonk Speedway is a family entertainment venue that features racing of all kinds on a semi-banked 1/3 mile asphalt-paved oval, located on U.S. Route 6 in Seekonk, Massachusetts. The track holds the distinction of being the longest continually family operated race track in the United States, under the guidance of the Venditti family since it opened on May 30, 1946. The track is sanctioned by NASCAR under the Whelen All-American Series. It is also the widest track in New England at 72 feet. The track's all-time winningest drivers include George Summers and "Radical" Rick Martin of Westport, Massachusetts.

Straight-six engine
The straight-six engine or inline-six engine (often abbreviated I6 or L6) is an internal combustion engine with the cylinders mounted in a straight line along the crankcase with all the pistons driving a common crankshaft (straight engine). The bank of cylinders may be oriented at any angle, and where the bank is inclined to the vertical, the engine is sometimes called a slant-six. The straight-six layout is the simplest engine layout that possesses both primary and secondary mechanical engine balance, resulting in much less vibration than engines with fewer cylinders. In automobiles, the straight-six design is used for engine displacements ranging from approximately .
Bicycle and motorcycle dynamics
Bicycle and motorcycle dynamics is the science of the motion of bicycles and motorcycles and their components, due to the forces acting on them. Dynamics falls under a branch of physics known as classical mechanics. Bike motions of interest include balancing, steering, braking, accelerating, suspension activation, and vibration. The study of these motions began in the late 19th century and continues today. Bicycles and motorcycles are both single-track vehicles and so their motions have many fundamental attributes in common and are fundamentally different from and more difficult to study than other wheeled vehicles such as dicycles, tricycles, and quadracycles.

Big-bang firing order
A big bang engine is an unconventional motorcycle engine designed so that most of the power strokes occur simultaneously or in close succession. This is achieved by changing the ignition timing, changing or re-timing the camshaft, and sometimes in combination with a change in crankpin angle. The goal is to change the power delivery characteristics of the engine. A regular firing multi-cylinder engine fires at approximately even intervals, giving a smooth-running engine. Because of a big bang engine's power delivery imbalance, there exists more vibration and stress in the engine. Thus, the power peaks are very strong and can overwhelm the rear tire (if used in a motorcycle), but when the rear tire does slide, the temporary lull in power between power strokes generally makes the slide easier to catch.
Straight-twin engine
A straight-twin engine, also known as straight-two, inline-twin, vertical-twin, or parallel-twin is a two-cylinder piston engine which has its cylinders arranged side by side and its pistons connected to a common crankshaft. Compared to V-twins and flat-twins, straight-twins are more compact, simpler, and usually cheaper to make, but may generate more vibration during operation. Straight-twin engines have been primarily used in motorcycles, but are also used in automobiles and in powersports applications. Automobiles with straight-twin engines are usually very small and include city cars and kei cars.
Honda Magna
The Honda Magna was a cruiser motorcycle made from 1982 to 1988 and 1994 to 2003 and powered by Honda's V4 engine taken from the VF/VFR. The engine technology and layout was a descendant of Honda's racing V4 machines, such as the NS750 and NR750. The introduction of this engine on the Magna and the Sabre in 1982, was a milestone in the evolution of motorcycles that would culminate in 1983 with the introduction of the Interceptor V4. The V45's performance is comparable to that of Valkyries and Honda's 1800 cc V-twin cruisers. However, its mix of performance, reliability, and refinement was overshadowed by the more powerful 1,098 cc "V65" Magna in 1983.

Suspension (motorcycle)
A motorcycle's suspension serves a dual purpose: contributing to the vehicle's handling and braking, and providing safety and comfort by keeping the vehicle's passengers comfortably isolated from road noise, bumps and vibrations. The typical motorcycle has a pair of fork tubes for the front suspension, and a swingarm with one or two shock absorbers for the rear suspension. The most common form of front suspension for a modern motorcycle is the telescopic fork. Other fork designs are girder forks, suspended on sprung parallel links (not common since the 1940s) and bottom leading link designs, not common since the 1960s.
City bicycle
A city bicycle, urban bicycle, European city bike (ECB), classic bike or simply city-bike, is a bicycle designed for frequent short, moderately paced rides through relatively flat urban areas. It is a form of utility bicycle commonly seen around the world, built to facilitate everyday riding in normal clothes in a variety of weather conditions. Generally as they are more suitable for urban environments, they focus more on comfort and practicality instead of speed or efficiency. They normally have a slightly curved, roughly planar aligned and elevated handlebar, providing users an upright sitting position.
Guy Martin
Guy Martin (born 4 November 1981) is a British lorry-mechanic better known publicly as a motorcycle racer and a television personality. Martin started racing in 1998, debuting on road circuits at the Isle of Man TT events in 2004, where he gained 15 podium finishes. He has broken his back twice in racing accidents, in the 2010 TT and the 2015 Ulster Grand Prix. Following the Ulster Grand Prix accident, Martin stated that he had retired from motorcycle racing although he never disclosed the decision publicly. However following numerous approaches by Honda Racing team manager Neil Tuxworth, Martin confirmed in January 2017 that he had signed for Lincolnshire-based Honda Racing as partner to 23-times TT winner John McGuinness for the North West 200, Isle of Man TT and Southern 100 races.
Mountain bike trials
Mountain bike trials, also known as observed trials, is a discipline of mountain biking in which the rider attempts to pass through an obstacle course without setting foot to ground. Derived from motorcycle trials, it originated in Catalonia, Spain and is said to have been invented by the father of Ot Pi, a world champion motorcycle trials rider. Pi's father had wanted his son to learn motorcycle trials by practicing on an ordinary bicycle. Trials riding is an extreme test of bicycle handling skills, over all kinds of obstacles, both natural and man-made. It now has a strong – though small – following worldwide, though it is still primarily a European sport.
Electric bicycle laws
Many countries have enacted electric bicycle laws to regulate the use of electric bicycles. Countries such as the United States and Canada have federal regulations governing the safety requirements and standards of manufacture. Other countries like the signatories of the European Union have agreed to wider-ranging legislation covering use and safety of their term EPAC (electric pedal-assisted cycles). However, confusion remains regarding the various laws involving electric bicycles. This stems from the fact that while some countries have national regulations, the legality of road use is left to states and provinces, and then complicated further by municipal laws and restrictions.
Disc brake
A disc brake is a type of brake that uses calipers to squeeze pairs of pads against a disc or "rotor" to create friction. This action retards the rotation of a shaft, such as a vehicle axle, either to reduce its rotational speed or to hold it stationary. The energy of motion is converted into waste heat which must be dispersed. Hydraulically actuated disc brakes are the most commonly used form of brake for motor vehicles, but the principles of a disc brake are applicable to almost any rotating shaft. Development of disc-type brakes began in England in the 1890s. In 1902, the Lanchester Motor Company designed brakes that looked and operated in a similar way to a modern disc-brake system even though the disc was thin and a cable activated the brake pad.
