Dymaxion Car
The Dymaxion car was designed by American inventor Buckminster Fuller during the Great Depression and featured prominently at Chicago's 1933/1934 World's Fair. Fuller built three experimental prototypes with naval architect Starling Burgess – using donated money as well as a family inheritance – to explore not an automobile per se, but the 'ground-taxiing phase' of a vehicle that might one day be designed to fly, land and drive – an "Omni-Medium Transport". Fuller associated the word ''Dymaxion'' with much of his work, a portmanteau of the words ''dynamic'', ''maximum'', and ''tension'', to summarize his goal to do more with less. The Dymaxion's aerodynamic bodywork was designed for increased fuel efficiency and top speed, and its platform featured a lightweight hinged chassis, rear-mounted V8 engine, front-wheel drive (a rare ''RF'' layout), and three wheels. With steering via its third wheel at the rear (capable of 90° steering lock), the vehicle co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Front-wheel Drive
Front-wheel drive (FWD) is a form of internal combustion engine, engine and transmission (mechanics), transmission layout used in motor vehicles, in which the engine drives the front wheels only. Most modern front-wheel-drive vehicles feature a transverse engine, rather than the conventional longitudinal engine arrangement generally found in automobile layout#Rear wheel drive layouts, rear-wheel-drive and four-wheel drive, four-wheel-drive vehicles. Location of engine and transmission By far the most common layout for a front-wheel-drive car is with the engine and transmission at the front of the car, mounted transversely. Other layouts of front-wheel drive that have been occasionally produced are a front-engine mounted longitudinally, a mid-engine layout and a rear-engine layout. History Prior to 1900 Experiments with front-wheel-drive cars date to the early days of the automobile. The world's first self-propelled vehicle, Nicolas-Joseph Cugnot's 1769/1770 Nicola ...

Locomobile Company Of America
The Locomobile Company of America was a pioneering American automobile manufacturer founded in 1899, and known for its dedication to precision before the assembly-line era. It was one of the earliest car manufacturers in the advent of the automobile age. For the first two years after its founding, the company was located in Watertown, Massachusetts. Production was transferred to Bridgeport, Connecticut, in 1900, where it remained until the company's demise in 1929. The company manufactured affordable, small steam cars until 1903, when production switched entirely to internal combustion-powered luxury automobiles. Locomobile was taken over in 1922 by Durant Motors and eventually went out of business in 1929. All cars produced by the original company were always sold under the brand name Locomobile. History The Locomobile Company of America was founded in 1899, the name coined from "locomotive" and "automobile". John B. Walker, editor and publisher of ''Cosmopolitan'', boug ...

Dynamometer
A dynamometer or "dyno" is a device for simultaneously measuring the torque and rotational speed ( RPM) of an engine, motor or other rotating prime mover so that its instantaneous power may be calculated, and usually displayed by the dynamometer itself as kW or bhp. In addition to being used to determine the torque or power characteristics of a machine under test, dynamometers are employed in a number of other roles. In standard emissions testing cycles such as those defined by the United States Environmental Protection Agency, dynamometers are used to provide simulated road loading of either the engine (using an engine dynamometer) or full powertrain (using a chassis dynamometer). Beyond simple power and torque measurements, dynamometers can be used as part of a testbed for a variety of engine development activities, such as the calibration of engine management controllers, detailed investigations into combustion behavior, and tribology. In the medical terminology, h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emergency Banking Act
__NOTOC__ The Emergency Banking Relief Act (E.B.R.A.), (), was an act passed by the United States Congress in March 1933 in an attempt to stabilize the banking system. Bank holiday Beginning on February 14, 1933, Michigan, an industrial state that had been hit particularly hard by the Great Depression in the United States, declared an eight-day bank holiday. Fears of other bank closures spread from state to state as people rushed to withdraw their deposits while they still could do so. Within weeks, all other states held their own bank holidays in an attempt to stem the bank runs, with Delaware becoming the 48th and last state to close its banks on March 4. Following his inauguration on March 4, 1933, President Franklin Roosevelt set out to rebuild confidence in the nation's banking system and to stabilize America's banking system. On March 6, he declared a four-day ''national'' banking holiday that kept all banks shut until Congress could act. During this time, the federal ...

Dymaxion Corporation At Bridgeport Connecticut
Dymaxion is a term coined by architect and inventor Buckminster Fuller and associated with much of his work, prominently his Dymaxion house and Dymaxion car. A portmanteau of the words ''dynamic'', ''maximum'', and ''tension'', Dymaxion sums up the goal of his study, "maximum gain of advantage from minimal energy input". Description A name was needed for the display of Fuller's first architectural model, later to be known as the Dymaxion house, at the Marshall Field's department store in Chicago. To create the name, wordsmith Waldo Warren was hired by Marshall Field's and spent two days listening to Fuller, getting a feel for his idiosyncratic use of language—later playing with the syllables typical of Fuller's speech until he and Fuller agreed on the word ''Dymaxion''. Fuller used the word for many of his inventions during the decades to follow, including the Dymaxion house, the Dymaxion deployment unit, the Dymaxion car, and the Dymaxion world map. Dymaxion also cam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Short (finance)
In finance, being short in an asset means investing in such a way that the investor will profit if the market value of the asset falls. This is the opposite of the more common Long (finance), long Position (finance), position, where the investor will profit if the market value of the asset rises. An investor that sells an asset short is, as to that asset, a short seller. There are a number of ways of achieving a short position. The most basic is physical selling short or short-selling, by which the short seller Securities lending, borrows an asset (often a security (finance), security such as a share (finance), share of stock or a bond (finance), bond) and sells it. The short seller must later buy the same amount of the asset to return it to the lender. If the market price of the asset has fallen in the meantime, the short seller will have made a profit equal to the difference in price. Conversely, if the price has risen then the short seller will bear a loss. The short seller ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isadora Duncan
Angela Isadora Duncan (May 26, 1877, or May 27, 1878 – September 14, 1927) was an American-born dancer and choreographer, who was a pioneer of modern contemporary dance and performed to great acclaim throughout Europe and the United States. Born and raised in California, she lived and danced in Western Europe, the U.S., and Soviet Russia from the age of 22. She died when her scarf became entangled in the wheel and axle of the car in which she was travelling in Nice, France. Early life Angela Isadora Duncan was born in San Francisco, the youngest of the four children of Joseph Charles Duncan (1819–1898), a banker, mining engineer and connoisseur of the arts, and Mary Isadora Gray (1849–1922). Her brothers were Augustin Duncan and Raymond Duncan; her sister, Elizabeth Duncan, was also a dancer. Soon after Isadora's birth, her father was investigated and charged following the collapse of the family’s bank, which coincided with a larger reorganization of San Francisco’ ...

The Last Dymaxion
''The Last Dymaxion: Buckminster Fuller's Dream Restored'' is a 2012 documentary film directed by Noel Murphy. about Buckminster Fuller's 1933 Dymaxion car as well as Fuller himself. The film features British architect Norman Foster, who called the car "an incredibly beautiful aesthetic object" and rebuilt the fourth Dymaxion car from drawings and study of the first three cars. In the film, noted automobile collector Jay Leno calls Buckminster Fuller a genius. Buckminster Fuller's advocacy for humanity permeates the film. Director Noel Murphy said describing "Buckminster Fuller as a car designer would be like describing Jimi Hendrix as a guitar tech". Fuller was a visionary environmentalist; his lightweight teardrop-shaped car spun on three wheels, held a dozen people and was originally meant to run on alcohol fuel. The documentary explores his other green innovations, including his geodesic domes and philosophical approach to architecture. Story Exploring Fuller's invention of ...

Turbulence
In fluid dynamics, turbulence or turbulent flow is fluid motion characterized by chaotic changes in pressure and flow velocity. It is in contrast to laminar flow, which occurs when a fluid flows in parallel layers with no disruption between those layers. Turbulence is commonly observed in everyday phenomena such as surf, fast flowing rivers, billowing storm clouds, or smoke from a chimney, and most fluid flows occurring in nature or created in engineering applications are turbulent. Turbulence is caused by excessive kinetic energy in parts of a fluid flow, which overcomes the damping effect of the fluid's viscosity. For this reason, turbulence is commonly realized in low viscosity fluids. In general terms, in turbulent flow, unsteady vortices appear of many sizes which interact with each other, consequently drag due to friction effects increases. The onset of turbulence can be predicted by the dimensionless Reynolds number, the ratio of kinetic energy to viscous damping ...

Aerodynamic Lift
When a fluid flows around an object, the fluid exerts a force on the object. Lift is the component of this force that is perpendicular to the oncoming flow direction. It contrasts with the drag force, which is the component of the force parallel to the flow direction. Lift conventionally acts in an upward direction in order to counter the force of gravity, but it is defined to act perpendicular to the flow and therefore can act in any direction. If the surrounding fluid is air, the force is called an aerodynamic force. In water or any other liquid, it is called a hydrodynamic force. Dynamic lift is distinguished from other kinds of lift in fluids. Aerostatic lift or buoyancy, in which an internal fluid is lighter than the surrounding fluid, does not require movement and is used by balloons, blimps, dirigibles, boats, and submarines. Planing lift, in which only the lower portion of the body is immersed in a liquid flow, is used by motorboats, surfboards, windsurfers, sailb ...
