American Eagle (roller Coaster)
American Eagle is a wooden racing roller coaster located at Six Flags Great America theme park in Gurnee, Illinois. It was the first wooden roller coaster designed by Intamin of Switzerland and was built in 1981 by the contracting firm Figley-Wright at a cost of $10 million. While most of the records have since been broken, American Eagle had the longest drop and fastest speeds among wooden roller coasters when it debuted and is still recognized as a top racing coaster in the United States. History Construction of American Eagle began in June 1980. The attraction was built with approximately of lumber, 129,720 bolts, and of nails. Supports are attached to approximately 2,000 concrete footings that average in diameter and are deep. American Eagle was painted with over of white paint and took over 20,000 man hours to build. American Eagle was designed by Curtis Summers, James Figley, and Leonard Wright. Marriott originally contacted John C. Allen to design the coaster, but he ...

Curtis D
Curtis or Curtiss is a common English given name and surname of Anglo-Norman origin from the Old French ''curteis'' ( Modern French ''courtois'') which derived from the Spanish Cortés (of which Cortez is a variation) and the Portuguese and Galician Cardoso. The name means "polite, courteous, or well-bred". It is a compound of ''curt-'' "court" and ''-eis'' "-ish". The spelling ''u'' to render in Old French was mainly Anglo-Norman and Norman, when the spelling ''o'' was the usual Parisian French one, Modern French ''ou'' ''-eis'' is the Old French suffix for ''-ois'', Western French (including Anglo-Norman) keeps ''-eis'', simplified to ''-is'' in English. The word ''court'' shares the same etymology but retains a Modern French spelling, after the orthography had changed.T. F. Hoad, ''English Etymology'', Oxford University Press paperbook 1993. p. 101a It was brought to England (and subsequently, the rest of the Isles) via the Norman Conquest. In the United Kingdom, th ...

The Wiggles
The Wiggles are an Australian children's music group formed in Sydney in 1991. The group are currently composed of Anthony Field, Lachlan Gillespie, Simon Pryce and Tsehay Hawkins, as well as supporting members Evie Ferris, John Pearce, Caterina Mete and Lucia Field. The Wiggles were founded in 1991 by Field, Murray Cook, Jeff Fatt, Greg Page and Phillip Wilcher. Wilcher left the group after their first album. Page retired in 2006 due to ill health and was replaced by understudy Sam Moran, but returned in 2012, replacing Moran. At the end of 2012, Cook, Fatt and Page retired and were replaced by Gillespie, Pryce and Emma Watkins. Cook and Fatt retained their shareholding in the group and all three continued to have input into its creative and production aspects. Watkins departed the group in 2021, with Hawkins taking her place.

Shockwave (Six Flags Great America)
Shockwave (occasionally stylized as ShockWave or Shock Wave) was a roller coaster manufactured by Arrow Dynamics at Six Flags Great America in Gurnee, Illinois. Standing tall and reaching speeds of , it opened in 1988 as the world's tallest and fastest looping roller coaster with a record-breaking seven inversions: three vertical loops, a boomerang (also known as a batwing), and two regular corkscrews. Shockwave was closed in 2002 and has been dismantled. History In late 1987, Six Flags Great America announced that they would be getting Shockwave for the 1988 season. The ride would be placed towards the front of the park in the Orleans Place section. Shockwave was set to open in April 1988, but the opening was delayed to June 3. Shockwave was designed by Ron Toomer at Arrow Dynamics, and its seven inversions set a new world record among roller coasters previously held by Vortex at Kings Island, which opened a year earlier. In 1989, Great American Scream Machine debuted at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Viper (Six Flags Great America)
Viper is a wooden roller coaster located at Six Flags Great America in Gurnee, Illinois, which opened in 1995. Viper is a clone of the Coney Island Cyclone and is the only roller coaster ever to be built directly by Six Flags. Viper is also the only wooden roller coaster with this name (all other roller coasters named Viper, both operating and not, have been steel roller coasters). It was built by Rygiel Construction. History In 1994, Six Flags Great America announced that they would be adding Viper. It would be a wooden roller coaster scheduled to open for the 1995 season. Construction of the coaster began in the fall of 1994 and was completed in early 1995. Viper opened on April 29, 1995. Throughout the years, Viper's queue has undergone numerous modifications to accommodate additions such as the addition of Raging Bull directly south of the ride and the former entrance to the adjacent Hurricane Harbor water park directly west of the ride. Unlike most clones of the Coney Isl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philadelphia Toboggan Company
Philadelphia Toboggan Coasters (PTC) is one of the oldest existing roller coaster manufacturing companies in the world. Based in Hatfield, Pennsylvania, it was established in 1904 by Henry Auchey and Chester Albright under the name Philadelphia Toboggan Company. The company manufactured carousels, wooden roller coasters, toboggans (roller coaster cars) and later, roller coaster trains. History The Philadelphia Toboggan Company was incorporated January 20, 1904. It built and designed roller coasters until 1979. Notable designers included Joe McKee, John A. Miller, Herbert Schmeck, Frank Hoover, and John C. Allen. When Allen retired as president in 1976, the company stopped designing roller coasters but continued to work on coaster projects until 1979 when it exited the coaster-construction industry permanently. The company manufactured carousels known for their elaborate carvings and decorations. It expanded with the acquisition of the inventory of the Dentzel Carousel Com ...

Train (roller Coaster)
A roller coaster train is a vehicle made up of two or more cars connected by specialized joints which transports passengers around a roller coaster's circuit. It is called a train because the cars follow one another around the track, the same reason as for a railroad train. Individual cars vary in design and can carry from one to eight or more passengers each. Many roller coasters operate more than one train, sometimes several, simultaneously. Typically they operate two trains at a time, with one train loading and unloading while the other train runs the course. On the Rock 'n' Roller Coaster at Walt Disney World, for example, there are five trains, but only four operate at a time (the trains are rotated out on a regular basis for safety reasons). Basic safety features Wheels Roller coaster trains have wheels that run on the sides (side friction or guide wheels) and underneath the track (upstop, underfriction, or underlocking wheels) as well as on top of it (road or running ...

Lift Hill
A lift hill, or chain hill, is an upward-sloping section of track on a roller coaster on which the roller coaster train is mechanically lifted to an elevated point or peak in the track. Upon reaching the peak, the train is then propelled from the peak by gravity and is usually allowed to coast throughout the rest of the roller coaster ride's circuit on its own momentum, including most or all of the remaining uphill sections. The initial upward-sloping section of a roller coaster track is usually a lift hill, as the train typically begins a ride with little speed, though some coasters have raised stations that permit an initial drop without a lift hill. Although uncommon, some tracks also contain multiple lift hills. Lift hills usually propel the train to the top of the ride via one of two methods: a chain lift involving a long, continuous chain which trains hook on to and are carried to the top; or a drive tire system in which multiple motorized tires (known as friction wheels) ...

Friction
Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: *Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact. Dry friction is subdivided into ''static friction'' ("stiction") between non-moving surfaces, and ''kinetic friction'' between moving surfaces. With the exception of atomic or molecular friction, dry friction generally arises from the interaction of surface features, known as asperities (see Figure 1). *Fluid friction describes the friction between layers of a viscous fluid that are moving relative to each other. *Lubricated friction is a case of fluid friction where a lubricant fluid separates two solid surfaces. *Skin friction is a component of drag, the force resisting the motion of a fluid across the surface of a body. *Internal friction is the force resisting motion between the elements making up a ...

Match Fixing
In organized sports, match fixing is the act of playing or officiating a match with the intention of achieving a pre-determined result, violating the rules of the game and often the law. There are many reasons why match fixing might take place, including receiving bribes from bookmakers or sports bettors, and blackmail. Competitors may also intentionally perform poorly to gain a future advantage, such as a better draft pick or to face an easier opponent in a later round of competition. A player might also play poorly to rig a handicap system. Match fixing, when motivated by gambling, requires contacts (and normally money transfers) between gamblers, players, team officials, and/or referees. These contacts and transfers can sometimes be discovered, and lead to prosecution by the law or the sports league(s). In contrast, losing for future advantage is internal to the team and very difficult to prove. Often, substitutions made by a coach designed to deliberately increase the tea ...

Center Of Mass
In physics, the center of mass of a distribution of mass in space (sometimes referred to as the balance point) is the unique point where the weighted relative position of the distributed mass sums to zero. This is the point to which a force may be applied to cause a linear acceleration without an angular acceleration. Calculations in mechanics are often simplified when formulated with respect to the center of mass. It is a hypothetical point where the entire mass of an object may be assumed to be concentrated to visualise its motion. In other words, the center of mass is the particle equivalent of a given object for application of Newton's laws of motion. In the case of a single rigid body, the center of mass is fixed in relation to the body, and if the body has uniform density, it will be located at the centroid. The center of mass may be located outside the physical body, as is sometimes the case for hollow or open-shaped objects, such as a horseshoe. In the case of a ...

Momentum
In Newtonian mechanics, momentum (more specifically linear momentum or translational momentum) is the product of the mass and velocity of an object. It is a vector quantity, possessing a magnitude and a direction. If is an object's mass and is its velocity (also a vector quantity), then the object's momentum is : \mathbf = m \mathbf. In the International System of Units (SI), the unit of measurement of momentum is the kilogram metre per second (kg⋅m/s), which is equivalent to the newton-second. Newton's second law of motion states that the rate of change of a body's momentum is equal to the net force acting on it. Momentum depends on the frame of reference, but in any inertial frame it is a ''conserved'' quantity, meaning that if a closed system is not affected by external forces, its total linear momentum does not change. Momentum is also conserved in special relativity (with a modified formula) and, in a modified form, in electrodynamics, quantum mechanics, ...
