Dymaxion Car
The streamlined 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), th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rear Engine
In automobile design, a rear-engine design layout places the engine at the rear of the vehicle. The center of gravity of the engine itself is behind the rear axle. This is not to be confused with the center of gravity of the whole vehicle, as an imbalance of such proportions would make it impossible to keep the front wheels on the ground. Rear-engined vehicles almost always have a rear-wheel drive car layout, but some are four wheel drive. This layout has the following features: *Packaging: since there is no need for a transmission tunnel, the floor can be flat. *Rear traction: having the engine located over the driven wheels increases downward pressure, which is helpful for grip on loose surfaces, although can be prone to oversteer. *Simplicity of manufacture: the engine is near the driven wheels, and the transmission can be merged with the differential to save space. This layout was once popular in small, inexpensive cars and light commercial vehicles. Today most car makers have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dynamometer
A dynamometer or "dyno" for short, 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, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emergency Banking Act
__NOTOC__ The Emergency Banking Act (EBA) (the official title of which was the Emergency Banking Relief Act), Public Law 73-1, 48 Stat. 1 (March 9, 1933), 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 a four-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'' bank ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. Dymaxion, a portmanteau of the words ''dynamic'', ''maximum'', and ''tension''; 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 al ...

Short (finance)
In finance, being short in an asset means investing in such a way that the investor will profit if the value of the asset falls. This is the opposite of a more conventional "long" position, where the investor will profit if the value of the asset rises. There are a number of ways of achieving a short position. The most fundamental method is "physical" selling short or short-selling, which involves borrowing assets (often securities such as shares or bonds) and selling them. The investor will later purchase the same number of the same type of securities in order to return them to the lender. If the price has fallen in the meantime, the investor will have made a profit equal to the difference. Conversely, if the price has risen then the investor will bear a loss. The short seller must usually pay a fee to borrow the securities (charged at a particular rate over time, similar to an interest payment), and reimburse the lender for any cash returns such as dividends that were due ...

Isadora Duncan
Angela Isadora Duncan (May 26, 1877 or May 27, 1878 – September 14, 1927) was an American dancer and choreographer, who was a pioneer of modern contemporary dance, who performed to great acclaim throughout Europe and the US. Born and raised in California, she lived and danced in Western Europe, the US and the Soviet Union from the age of 22 until her death at age 50 when her scarf became entangled in the wheel and axle of the car in which she was travelling in Nice, France. Early life 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 found to have been using funds from two banks he had helped set up to finance his private stock speculations. Although he avoided prison time, I ...

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 ...

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 a 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. This increases the energy needed to pump fluid through a pipe. The onset of turbulence can be predicted by the dimensionless Rey ...

Aerodynamic Lift
A fluid flowing around an object exerts a force on it. 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 can act in any direction at right angles to the flow. 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, sailboats, and water-skis. Overview A fluid flowing aro ...

Steering
Steering is a system of components, linkages, and other parts that allows a driver to control the direction of the vehicle. Introduction The most conventional steering arrangement allows a driver to turn the front wheels of a vehicle using a hand–operated steering wheel positioned in front of the driver. The steering wheel is attached to a steering column A column or pillar in architecture and structural engineering is a structural element that transmits, through compression, the weight of the structure above to other structural elements below. In other words, a column is a compression member. ..., which is linked to rods, pivots and gears that allow the driver to change the direction of the front wheels. Other arrangements are sometimes found on different types of vehicles; for example, a tiller or rear-wheel steering. Tracked vehicles such as bulldozers and tanks usually employ differential steering, where the tracks are made to move at different speeds or even in ...
