Rollback (roller Coaster)
A rollback occurs on a launched roller coaster when the train is not launched fast enough to reach the top of the tower or hill. It will roll backwards down the tower, and will be stopped by brakes on the launch track. Any roller coaster on which it is possible for a rollback to occur will have these brakes. Intamin, a manufacturer of roller-coasters, refers to the "rollback" as a "short shot". Most coasters contain at least one anti-rollback device to prevent a train from rolling backwards while ascending the main lift. This is typically with chain-driven lifts, not hydraulic launchers such as Kingda Ka. Factors Rollbacks are most common (though still quite rare) on the world's largest launched roller coasters like Top Thrill Dragster at Cedar Point and Kingda Ka at Six Flags Great Adventure, along with somewhat smaller rides such as Stealth at Thorpe Park and launched roller coasters of the same type, such as Xcelerator at Knott's Berry Farm and Storm Runner at Hers ...

Friction
Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. Types of friction include dry, fluid, lubricated, skin, and internal -- an incomplete list. The study of the processes involved is called tribology, and has a history of more than 2000 years. Friction can have dramatic consequences, as illustrated by the use of friction created by rubbing pieces of wood together to start a fire. Another important consequence of many types of friction can be wear, which may lead to performance degradation or damage to components. It is known that frictional energy losses account for about 20% of the total energy expenditure of the world. As briefly discussed later, there are many different contributors to the retarding force in friction, ranging from asperity deformation to the generation of charges and changes in local structure. When two bodies in contact move relative to each other, due to these variou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Launched Roller Coaster
The launched roller coaster is a type of roller coaster that initiates a ride with high amounts of acceleration via one or a series of linear induction motors (LIM), linear synchronous motors (LSM), catapults, tires, chains, or other mechanisms employing hydraulic or pneumatic power, along a launch track. This mode of acceleration powers many of the fastest roller coasters in the world. Electromagnetic LIM / LSM Linear induction motor (LIM) and linear synchronous motor (LSM) coasters use propulsion via electromagnets, which utilize large amounts of electricity to propel the coaster train along its track into the ride elements (e.g. inversions, twists, turns and short drops). Ten design companies managing these types of rides are Vekoma, Intamin, Gerstlauer, Premier Rides, Maurer, Zierer, Mack Rides, Bolliger & Mabillard, Rocky Mountain Construction and S&S Worldwide. Both Rocky Mountain Construction and Bolliger & Mabillard established their first LSM launched co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
