Private Company
A privately held company (or simply a private company) is a company whose shares and related rights or obligations are not offered for public subscription or publicly negotiated in the respective listed markets, but rather the company's stock is offered, owned, traded, exchanged privately, or Over-the-counter (finance), over-the-counter. In the case of a closed corporation, there are a relatively small number of shareholders or company members. Related terms are closely-held corporation, unquoted company, and unlisted company. Though less visible than their public company, publicly traded counterparts, private companies have major importance in the world's economy. In 2008, the 441 list of largest private non-governmental companies by revenue, largest private companies in the United States accounted for ($1.8 trillion) in revenues and employed 6.2 million people, according to ''Forbes''. In 2005, using a substantially smaller pool size (22.7%) for comparison, the 339 companies on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cannondale Prepared By Cyclocrossworld
The Cannondale Bicycle Corporation is an American division of Dutch conglomerate Pon Holdings that supplies bicycles. Its headquarters are in Wilton, Connecticut with engineering offices in Freiburg, Germany. Frames are manufactured in Taiwan. History The company was founded in 1971 by Joe Montgomery and Murdock MacGregor to manufacture precast concrete housing. Later Ron Davis came to Cannondale from CBS Laboratories where he was vice-president in charge of the development of microfilm reproduction. Davis had an idea for an internal combustion engine that would use ammonia as fuel. Davis, with MacGregor as his assistant, managed to duplicate and exceed results obtained by Allison Engine, then a division of General Motors. Faced with a commitment to invest a large amount of capital to take the project to a workable model installed in an automobile, Montgomery decided that the company should raise capital by developing and marketing other products that they had conceived.

Toroid
In mathematics, a toroid is a surface of revolution with a hole in the middle. The axis of revolution passes through the hole and so does not intersect the surface. For example, when a rectangle is rotated around an axis parallel to one of its edges, then a hollow rectangle-section ring is produced. If the revolved figure is a circle, then the object is called a torus. The term ''toroid'' is also used to describe a toroidal polyhedron. In this context a toroid need not be circular and may have any number of holes. A ''g''-holed ''toroid'' can be seen as approximating the surface of a torus having a topological genus, ''g'', of 1 or greater. The Euler characteristic χ of a ''g'' holed toroid is 2(1-''g'').Stewart, B.; "Adventures Among the Toroids:A Study of Orientable Polyhedra with Regular Faces", 2nd Edition, Stewart (1980). The torus is an example of a toroid, which is the surface of a doughnut. Doughnuts are an example of a solid torus created by rotating a disk, and s ...

Moment Of Inertia
The moment of inertia, otherwise known as the mass moment of inertia, angular mass, second moment of mass, or most accurately, rotational inertia, of a rigid body is a quantity that determines the torque needed for a desired angular acceleration about a rotational axis, akin to how mass determines the force needed for a desired acceleration. It depends on the body's mass distribution and the axis chosen, with larger moments requiring more torque to change the body's rate of rotation. It is an extensive (additive) property: for a point mass the moment of inertia is simply the mass times the square of the perpendicular distance to the axis of rotation. The moment of inertia of a rigid composite system is the sum of the moments of inertia of its component subsystems (all taken about the same axis). Its simplest definition is the second moment of mass with respect to distance from an axis. For bodies constrained to rotate in a plane, only their moment of inertia about an axis ...

Team CSC
Tinkoff () was a Russian-registered professional cycling team from Russia and previously Denmark. It competed in the UCI World Tour. The team was owned by Russian Oleg Tinkov and, from 1999 until March 2015, was managed by former Tour de France winner Bjarne Riis. The team was sponsored by the Russian Tinkoff Bank, a credit systems company. Founded in 1998 as home-Jack & Jones, the team started in cycling's second division. In 2000 it moved into the top division, now known as the UCI World Tour. Since 2000, under differing sponsor names (Memory Card-Jack & Jones and CSC-Tiscali), the team rode the Tour de France. It has won the overall classification in all three of the Grand Tours. In the 2008 Tour de France, Carlos Sastre won the general classification, Andy Schleck won the young rider classification, and the team won the overall team classification, and Ivan Basso won the 2006 Giro d'Italia, as well as finishing third and second in the 2004 and 2005 Tour de France.

Time Trial Bike Ellen Van Dijk 2014
Time is the continued sequence of existence and events that occurs in an apparently irreversible succession from the past, through the present, into the future. It is a component quantity of various measurements used to sequence events, to compare the duration of events or the intervals between them, and to quantify rates of change of quantities in material reality or in the conscious experience. Time is often referred to as a fourth dimension, along with three spatial dimensions. Time has long been an important subject of study in religion, philosophy, and science, but defining it in a manner applicable to all fields without circularity has consistently eluded scholars. Nevertheless, diverse fields such as business, industry, sports, the sciences, and the performing arts all incorporate some notion of time into their respective measuring systems. 108 pages. Time in physics is operationally defined as "what a clock reads". The physical nature of time is addressed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wind Tunnel
Wind tunnels are large tubes with air blowing through them which are used to replicate the interaction between air and an object flying through the air or moving along the ground. Researchers use wind tunnels to learn more about how an aircraft will fly. NASA uses wind tunnels to test scale models of aircraft and spacecraft. Some wind tunnels are large enough to contain full-size versions of vehicles. The wind tunnel moves air around an object, making it seem as if the object is flying. Most of the time, large powerful fans suck air through the tube. The object being tested is held securely inside the tunnel so that it remains stationary. The object can be an aerodynamic test object such as a cylinder or an airfoil, an individual component, a small model of the vehicle, or a full-sized vehicle. The air moving around the stationary object shows what would happen if the object was moving through the air. The motion of the air can be studied in different ways; smoke or dye can be ...

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 ...

Zipp 2001
Zipp 2001 and 3001 were a line of bicycle frames, now discontinued, made by the Zipp company. Though they have been out of production since 1997, they are still considered one of the fastest time trial frames ever made , and still have a cult following within triathlon, where they remain race-legal . The mid-1990s were a fertile time for bicycle designers. New materials (aluminum, carbon fiber) presented new design possibilities, and a number of "non-traditional" designs appeared. While the Zipp 2001 may be one of the better known products, other frames made in this era included Hotta, Softride Softride was a manufacturer of bicycles located in Bellingham, Washington. They specialized in bicycles for triathletes. The bicycle frames were distinctive for their lack of seat tubes and seat stays. The idea was to reduce aerodynamic drag an ..., Trek's Y-foil, and the Cheetah Cat. Theory Timeline The frame that was to become the 2001 was first shown in prototype form in 1 ...
