A gear or cogwheel is a rotating machine part having cut teeth, or cogs, which mesh with another toothed part in order to transmit torque. Two or more gears working in tandem are called a transmission and can produce a mechanical advantage through a gear ratio and thus may be considered a simple machine. Geared devices can change the speed, torque, and direction of a power source. The most common situation is for a gear to mesh with another gear; however, a gear can also mesh with a non-rotating toothed part, called a rack, thereby producing translation instead of rotation. The gears in a transmission are analogous to the wheels in a pulley. An advantage of gears is that the teeth of a gear prevent slipping. When two gears of unequal number of teeth are combined, a mechanical advantage is produced, with both the rotational speeds and the torques of the two gears differing in a simple relationship. In transmissions which offer multiple gear ratios, such as bicycles and cars, the term gear, as in first gear, refers to a gear ratio rather than an actual physical gear. The term is used to describe similar devices even when the gear ratio is continuous rather than discrete, or when the device does not actually contain any gears, as in a continuously variable transmission.
Fifth Gear is a British motoring television magazine series. Originally shown on Channel 5 from 2002 to 2011 and Discovery since 2012, the show is currently presented by Tiff Needell, Vicki Butler-Henderson, Jason Plato and Jonny Smith. Fifth Gear's rival show is BBC Two's Top Gear. Fifth Gear was first broadcast on 8 April 2002 as 5th Gear, and as a continuation of the original incarnation of the BBC show Top Gear, which was cancelled in 2001. Top Gear was relaunched later that year; Channel 5 originally wanted to carry on using the Top Gear name, but the BBC refused. Several of Top Gear's ex-presenters, including Quentin Willson, Tiff Needell, and Vicki Butler-Henderson were hired by Channel 5 to present Fifth Gear. The show was renamed as Fifth Gear in 2005. Repeats of Fifth Gear also started being broadcast on UKTV channel, Dave in April 2008 and later on Discovery Turbo.
A gear train is formed by mounting gears on a frame so that the teeth of the gears engage. Gear teeth are designed to ensure the pitch circles of engaging gears roll on each other without slipping, this provides a smooth transmission of rotation from one gear to the next. The transmission of rotation between contacting toothed wheels can be traced back to the Antikythera mechanism of Greece and the South Pointing Chariot of China. Illustrations by the renaissance scientist Georgius Agricola show gear trains with cylindrical teeth. The implementation of the involute tooth yielded a standard gear design that provides a constant speed ratio. Some important features of gears and gear trains are: ⁕The ratio of the pitch circles of mating gears defines the speed ratio and the mechanical advantage of the gear set. ⁕A planetary gear train provides high gear reduction in a compact package. ⁕It is possible to design gear teeth for gears that are non-circular, yet still transmit torque smoothly. ⁕The speed ratios of chain and belt drives are computed in the same way as gear ratios. See bicycle gearing.
A pinion is a round gear used in several applications: ⁕usually the smallest gear in a gear drive train, although in the case of John Blenkinsop's Salamanca, the pinion was rather large. In many cases, such as remote controlled toys, the pinion is also the drive gear. ⁕the smaller gear that drives in a 90-degree angle towards a crown gear in a differential drive. ⁕the small front sprocket on a chain driven motorcycle. ⁕the round gear that engages and drives a rack in a rack and pinion mechanism and against a rack in a rack railway. ⁕in the case of radio-controlled cars with an engine this pinion gear can be referred to as a clutch bell when it is paired with a centrifugal clutch.
The gear ratio of a gear train, also known as its speed ratio, is the ratio of the angular velocity of the input gear to the angular velocity of the output gear. The gear ratio can be calculated directly from the numbers of teeth on the gears in the gear train. The torque ratio of the gear train, also known as its mechanical advantage, is determined by the gear ratio. The speed ratio and mechanical advantage are defined so they yield the same number in an ideal linkage.
A fixed-gear bicycle is a bicycle that has a drivetrain with no freewheel mechanism. The freewheel was developed early in the history of bicycle design but the fixed-gear bicycle remained the standard track racing design. More recently the 'fixie' has become a popular alternative among mainly urban cyclists, offering the advantages of simplicity compared with the standard multi-geared bicycle. Most bicycles incorporate a freewheel to allow the pedals to remain stationary while the bicycle is in motion, so that the rider can coast, i.e., ride without pedalling using the forward or downhill momentum of bike and rider. A fixed-gear drivetrain has the drive sprocket threaded or bolted directly to the hub of the back wheel, so that the rider cannot stop pedalling. When the rear wheel turns, the pedals turn in the same direction. This allows a cyclist to apply a weak braking force without using a brake, by resisting the rotation of the cranks. It also makes it possible to ride backwards although learning to do so is much more difficult than riding forward. As a general rule, fixed-gear bicycles are single-speed. A derailleur cannot be fitted because the chain cannot have any slack, but hub gearing can, for example a Sturmey-Archer fixed-gear 3-speed hub, in which case is a fixed-gear multi-speed arrangement. Most fixed-gear bicycles only have a front brake, and some have no brakes at all.
An escapement is a device in mechanical watches and clocks that transfers energy to the timekeeping element and allows the number of its oscillations to be counted. The impulse action transfers energy to the clock's timekeeping element to replace the energy lost to friction during its cycle, to keep the timekeeper oscillating. The escapement is driven by force from a coiled spring or a suspended weight, transmitted through the timepiece's gear train. The amount of stored energy, energy loss and efficiency of transfer to the timekeeping element determines the time a clock will run after it has been wound. The escapement releases the tooth of a gear, which therefore changes from a "locked" state to a "drive" state until the opposite arm strikes another tooth on the gear, which locks the gear again. A clock's tick is the sound of the gear train stopping as the escapement locks. The gear train is accelerated and decelerated with each tick of the clock. This locking action of the escapement allows each cycle of the timekeeping element to be counted. During each cycle the escapement permits a gear train to advance or escape slightly. The periodic advancement results in moving the timepiece's hands forward at a steady rate. This starting and stopping accounts for most of the energy usage from the spring or weight when a clock is in good working order.
Chain drive is a way of transmitting mechanical power from one place to another. It is often used to convey power to the wheels of a vehicle, particularly bicycles and motorcycles. It is also used in a wide variety of machines besides vehicles. Most often, the power is conveyed by a roller chain, known as the drive chain or transmission chain, passing over a sprocket gear, with the teeth of the gear meshing with the holes in the links of the chain. The gear is turned, and this pulls the chain putting mechanical force into the system. Another type of drive chain is the Morse chain, invented by the Morse Chain Company of Ithaca, New York, USA. This has inverted teeth. Sometimes the power is output by simply rotating the chain, which can be used to lift or drag objects. In other situations, a second gear is placed and the power is recovered by attaching shafts or hubs to this gear. Though drive chains are often simple oval loops, they can also go around corners by placing more than two gears along the chain; gears that do not put power into the system or transmit it out are generally known as idler-wheels. By varying the diameter of the input and output gears with respect to each other, the gear ratio can be altered, so that, for example, the pedals of a bicycle can spin all the way around more than once for every rotation of the gear that drives the wheels.
A gear pump uses the meshing of gears to pump fluid by displacement. They are one of the most common types of pumps for hydraulic fluid power applications. Gear pumps are also widely used in chemical installations to pump fluid with a certain viscosity. There are two main variations; external gear pumps which use two external spur gears, and internal gear pumps which use an external and an internal spur gear. Gear pumps are positive displacement, meaning they pump a constant amount of fluid for each revolution. Some gear pumps are designed to function as either a motor or a pump.
Dr. Hal Emmerich, nicknamed Otacon, is a fictional character from Konami's Metal Gear series. Created by Hideo Kojima and designed by Yoji Shinkawa, Otacon was introduced in the series in Metal Gear Solid. In Metal Gear Solid, Otacon, an ArmsTech employee who designed Metal Gear REX, becomes a close ally of Solid Snake upon learning of REX's nuclear strike capabilities. After the events of Metal Gear Solid, he helped Solid Snake form Philanthropy, a group whose main objective is to prevent proliferation of Metal Gear-type weapons. Snake and Otacon infiltrate the military installations and facilities of the world, delving into their compounds through stealth and cyber hacking. In a sense, Snake is the brawn and Otacon is the brains behind "Philanthropy." A devoted fan of anime, Hal's chosen nickname is the short form of the Otaku Convention, with reference to Otakon held in Baltimore each year. The name "Hal" is a direct reference to the computer HAL 9000 from the film 2001: A Space Odyssey, one of several references to the film which is present in Metal Gear Solid; in the Otacon ending of the game, Hal and Snake make direct comparisons to the film.

An automatic is one type of motor vehicle transmission that can automatically change gear ratios as the vehicle moves, freeing the driver from having to shift gears manually. Most automatic transmissions have a defined set of gear ranges, often with a parking pawl feature that locks the output shaft of the transmission. Similar but larger devices are also used for heavy-duty commercial and industrial vehicles and equipment. Some machines with limited speed ranges or fixed engine speeds, such as some forklifts and lawn mowers, only use a torque converter to provide a variable gearing of the engine to the wheels. Besides automatics, there are also other types of automated transmissions such as a continuously variable transmission and semi-automatic transmissions, that free the driver from having to shift gears manually, by using the transmission's computer to change gear, if for example the driver were redlining the engine. Despite superficial similarity to other transmissions, automatic transmissions differ significantly in internal operation and driver's feel from semi-automatics and CVTs. An automatic uses a torque converter instead of a clutch to manage the connection between the transmission gearing and the engine. In contrast, a CVT uses a belt or other torque transmission scheme to allow an "infinite" number of gear ratios instead of a fixed number of gear ratios. A semi-automatic retains a clutch like a manual transmission, but controls the clutch through electrohydraulic means.
A belly landing or gear-up landing occurs when an aircraft lands without its landing gear fully extended and uses its underside, or belly, as its primary landing device. Normally the term gear-up landing refers to incidents in which the pilot forgets to extend the landing gear, while belly landing refers to incidents where a mechanical malfunction prevents the pilot from extending the landing gear. During a belly landing, there is normally extensive damage to the airplane. Belly landings carry the risk that the aircraft may flip over, disintegrate, or catch fire if it lands too fast or too hard. Extreme precision is needed to ensure that the plane lands as straight and level as possible while maintaining enough airspeed to maintain control. Strong crosswinds, low visibility, damage to the airplane, or unresponsive instruments or controls greatly increase the danger of performing a belly landing. Still, belly landings are one of the most common types of aircraft accidents, and are normally not fatal if executed carefully.
