 picture info Manual Transmission Animation: shifting mechanism of a gearbox with 4 gears A manual transmission, also known as a manual gearbox, or colloquially in some countries (e.g. the United States) as a stick shift is a type of transmission used in motor vehicle applications. It uses a driver-operated clutch engaged and disengaged by a foot pedal (automobile) or hand lever (motorcycle), for regulating torque transfer from the engine to the transmission; and a gear selector operated by hand (automobile) or by foot (motorcycle). A conventional 5-speed manual transmission is often the standard equipment in a base-model vehicle, while more expensive manual vehicles are usually equipped with a 6-speed transmission instead; other options include automatic transmissions such as a traditional automatic (hydraulic planetary) transmission (often a manumatic), a semi-automatic transmission, or a continuously variable transmission (CVT) [...More Info...]       [...Related Items...] picture info Flywheel A flywheel is a mechanical device specifically designed to efficiently store rotational energy. Flywheels resist changes in rotational speed by their moment of inertia. The amount of energy stored in a flywheel is proportional to the square of its rotational speed. The way to change a flywheel's stored energy is by increasing or decreasing its rotational speed by applying a torque aligned with its axis of symmetry, Common uses of a flywheel include: picture info United States The United States of America (USA), commonly known as the United States (U.S. or US) or America, is a country comprising 50 states, a federal district, five major self-governing territories, and various possessions. At 3.8 million square miles (9.8 million km2--->), it is the world's third or fourth-largest country by total area and is slightly smaller than the entire continent of Europe. Most of the country is located in central North America between Canada and Mexico. With an estimated population of over 328 million, the U.S. is the third most populous country. The capital is Washington, D.C., and the most populous city is New York City. Paleo-Indians migrated from Siberia to the North American mainland at least 12,000 years ago. European colonization began in the 16th century [...More Info...]       [...Related Items...] picture info Brass Brass is a metallic alloy that is made of copper and zinc. The proportions of zinc and copper can vary to create different types of brass alloys with varying mechanical and electrical properties. It is a substitutional alloy: atoms of the two constituents may replace each other within the same crystal structure. In contrast, bronze is an alloy of copper and tin. Both bronze and brass may include small proportions of a range of other elements including arsenic, lead, phosphorus, aluminium, manganese, and silicon [...More Info...]       [...Related Items...] picture info Throttle A throttle is the mechanism by which fluid flow is managed by constriction or obstruction. An engine's power can be increased or decreased by the restriction of inlet gases (by the use of a throttle), but usually decreased. The term throttle has come to refer, informally, to any mechanism by which the power or speed of an engine is regulated, such as a car's accelerator pedal. What is often termed a throttle (in an aviation context) is also called a thrust lever, particularly for jet engine powered aircraft [...More Info...]       [...Related Items...] picture info Power Band The power band of an internal combustion engine or electric motor is the range of operating speeds under which the engine or motor is able to operate most efficiently. While engines and motors have a large range of operating speeds, the power band is usually a much smaller range of engine speed, only half or less of the total engine speed range (electric motors are an exception—see the section on electric motors below). Specifically, power band is the range of RPM around peak power output. The power band of an internal combustion gasoline automobile engine typically starts at midrange engine speeds (around 4,000 RPM) where maximum torque is produced, and ends close to the redline after reaching maximum power between 5,000 and 6,500 RPM [...More Info...]       [...Related Items...] Commercial Motor Vehicle A commercial vehicle is any type of motor vehicle used for transporting goods or paying passengers. The European Union defines a "commercial motor vehicle" as any motorised road vehicle, that by its type of construction and equipment is designed for, and capable of transporting, whether for payment or not: (1) more than nine persons, including the driver; (2) goods and "standard fuel tanks". This means the tanks permanently fixed by the manufacturer to all motor vehicles of the same type as the vehicle in question and whose permanent fitting lets fuel be used directly, both for propulsion and, where appropriate, to power a refrigeration system [...More Info...]       [...Related Items...] picture info Thrust Bearing A thrust bearing is a particular type of rotary bearing. Like other bearings they permit rotation between parts, but they are designed to support a predominantly axial load. Thrust bearings come in several varieties. picture info Linkage (mechanical) A mechanical linkage is an assembly of bodies connected to manage forces and movement. The movement of a body, or link, is studied using geometry so the link is considered to be rigid. The connections between links are modeled as providing ideal movement, pure rotation or sliding for example, and are called joints. A linkage modeled as a network of rigid links and ideal joints is called a kinematic chain. Linkages may be constructed from open chains, closed chains, or a combination of open and closed chains. Each link in a chain is connected by a joint to one or more other links [...More Info...]       [...Related Items...] picture info Internal Combustion Engine An internal combustion engine (ICE) is a heat engine where the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high-temperature and high-pressure gases produced by combustion applies direct force to some component of the engine. The force is applied typically to pistons, turbine blades, rotor or a nozzle [...More Info...]       [...Related Items...] picture info Torque Torque, moment, or moment of force is rotational force. Just as a linear force is a push or a pull, a torque can be thought of as a twist to an object. In three dimensions, the torque is a pseudovector; for point particles, it is given by the cross product of the position vector (distance vector) and the force vector. The symbol for torque is typically ${\displaystyle \tau }$, the lowercase Greek letter tau. When it is called moment of force, it is commonly denoted by M. The magnitude of torque of a rigid body depends on three quantities: the force applied, the lever arm vector connecting the origin to the point of force application, and the angle between the force and lever arm vectors [...More Info...]       [...Related Items...] picture info Porsche Dr. Ing. h.c.

Almost as soon as automobiles had been invented, races of various sorts were organised, with the first recorded as early as 1867. Many of the earliest events were effectively reliability trials, aimed at proving these new machines were a practical mode of transport, but soon became an important way for competing makers to demonstrate their machines [...More Info...]       [...Related Items...] picture info Motor Vehicle A motor vehicle is a self-propelled vehicle, commonly wheeled, that does not operate on rails, such as trains or trams and used for the transportation of passengers, or passengers and property. The vehicle propulsion is provided by an engine or motor, usually by an internal combustion engine, or an electric motor, or some combination of the two, such as hybrid electric vehicles and plug-in hybrids. For legal purposes motor vehicles are often identified within a number of vehicle classes including cars, buses, motorcycles, off-road vehicles, light trucks and regular trucks. These classifications vary according to the legal codes of each country [...More Info...]       [...Related Items...] picture info Porsche 356 The Porsche 356 is a luxury sports car which was first produced by Austrian company Porsche Konstruktionen GesmbH (1948–1949), and then by German company Dr. Ing. h. c. F. Porsche GmbH (1950–1965). It was Porsche's first production automobile. Earlier cars designed by the Austrian company include Cisitalia Grand Prix race car, the Volkswagen Beetle, and Auto Union Grand Prix cars. The 356 is a lightweight and nimble-handling, rear-engine, rear-wheel drive, two-door available both in hardtop coupé and open configurations. Engineering innovations continued during the years of manufacture, contributing to its motorsports success and popularity. Production started in 1948 at Gmünd, Austria, where approximately 50 cars were built. In 1950 the factory relocated to Zuffenhausen, Germany, and general production of the 356 continued until April 1965, well after the replacement model 911 made its autumn 1963 debut [...More Info...]       [...Related Items...] picture info Truck A truck or lorry is a motor vehicle designed to transport cargo. Trucks vary greatly in size, power, and configuration; smaller varieties may be mechanically similar to some automobiles. Commercial trucks can be very large and powerful and may be configured to be mounted with specialized equipment, such as in the case of refuse trucks, fire trucks, concrete mixers, and suction excavators. In American English, a commercial vehicle without a trailer or other articulation is formally a "straight truck" while one designed specifically to pull a trailer is not a truck but a "tractor". Modern trucks are largely powered by diesel engines, although small to medium size trucks with gasoline engines exist in the US, Canada, and Mexico [...More Info...]       [...Related Items...]
