Physics Of Roller Coasters
The physics of roller coasters comprises the mechanics that affect the design and operation of roller coasters, a machine that uses gravity and inertia to send a train of cars along a winding track. Gravity, inertia, g-forces, and centripetal acceleration give riders constantly changing forces which create certain sensations as the coaster travels around the track. Introduction A roller coaster is a machine that uses gravity and inertia to send a train of cars along a winding track. The combination of gravity and inertia, along with g-forces and centripetal acceleration give the body certain sensations as the coaster moves up, down, and around the track. The forces experienced by the rider are constantly changing, leading to feelings of joy in some riders and nausea in others. Energy Initially, the car is pulled to the top of the first hill and released, at which point it rolls freely along the track without any external mechanical assistance for the remainder of the ride.

Roller Coaster
A roller coaster, or rollercoaster, is a type of amusement ride that employs a form of elevated railroad track designed with tight turns, steep slopes, and sometimes inversions. Passengers ride along the track in open cars, and the rides are often found in amusement parks and theme parks around the world. LaMarcus Adna Thompson obtained one of the first known patents for a roller coaster design in 1885, related to the Switchback Railway that opened a year earlier at Coney Island. The track in a coaster design does not necessarily have to be a complete circuit, as shuttle roller coasters demonstrate. Most roller coasters have multiple cars in which passengers sit and are restrained. Two or more cars hooked together are called a train. Some roller coasters, notably Wild Mouse roller coasters, run with single cars. History The Russian mountain and the Aerial Promenades The oldest roller coasters are believed to have originated from the so-called "Russian Mountains", speciall ...

G-force
The gravitational force equivalent, or, more commonly, g-force, is a measurement of the type of force per unit mass – typically acceleration – that causes a perception of weight, with a g-force of 1 g (not gram in mass measurement) equal to the conventional value of gravitational acceleration on Earth, ''g'', of about . Since g-forces indirectly produce weight, any g-force can be described as a "weight per unit mass" (see the synonym specific weight). When the g-force is produced by the surface of one object being pushed by the surface of another object, the reaction force to this push produces an equal and opposite weight for every unit of each object's mass. The types of forces involved are transmitted through objects by interior mechanical stresses. Gravitational acceleration (except certain electromagnetic force influences) is the cause of an object's acceleration in relation to free fall. The g-force experienced by an object is due to the vector sum of all ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tubular Steel
Cold-formed steel (CFS) is the common term for steel products shaped by cold-working processes carried out near room temperature, such as rolling, pressing, stamping, bending, etc. Stock bars and sheets of cold-rolled steel (CRS) are commonly used in all areas of manufacturing. The terms are opposed to hot-formed steel and hot-rolled steel. Cold-formed steel, especially in the form of thin gauge sheets, is commonly used in the construction industry for structural or non-structural items such as columns, beams, joists, studs, floor decking, built-up sections and other components. Such uses have become more and more popular in the US since their standardization in 1946. Cold-formed steel members have been used also in bridges, storage racks, grain bins, car bodies, railway coaches, highway products, transmission towers, transmission poles, drainage facilities, firearms, various types of equipment and others. These types of sections are cold-formed from steel sheet, strip ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engineers
Engineers, as practitioners of engineering, are professionals who invent, design, analyze, build and test machines, complex systems, structures, gadgets and materials to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost. "Science is knowledge based on our observed facts and tested truths arranged in an orderly system that can be validated and communicated to other people. Engineering is the creative application of scientific principles used to plan, build, direct, guide, manage, or work on systems to maintain and improve our daily lives." The word ''engineer'' (Latin ) is derived from the Latin words ("to contrive, devise") and ("cleverness"). The foundational qualifications of an engineer typically include a four-year bachelor's degree in an engineering discipline, or in some jurisdictions, a master's degree in an engineering discipline plus four to six years of peer-reviewed professional pr ...

Technology
Technology is the application of knowledge to reach practical goals in a specifiable and reproducible way. The word ''technology'' may also mean the product of such an endeavor. The use of technology is widely prevalent in medicine, science, industry, communication, transportation, and daily life. Technologies include physical objects like utensils or machines and intangible tools such as software. Many technological advancements have led to societal changes. The earliest known technology is the stone tool, used in the prehistoric era, followed by fire use, which contributed to the growth of the human brain and the development of language in the Ice Age. The invention of the wheel in the Bronze Age enabled wider travel and the creation of more complex machines. Recent technological developments, including the printing press, the telephone, and the Internet have lowered communication barriers and ushered in the knowledge economy.

Silver Dollar City
Silver Dollar City is a amusement park in Stone County, Missouri, near the cities of Branson and Branson West. The park is located off of Missouri Route 76 on the Indian Point peninsula of Table Rock Lake. Silver Dollar City opened on May 1, 1960. The park is an 1880s-themed experience that fits Branson's vision as a family-friendly vacation destination with down-home charm. Silver Dollar City's operating season runs from March until December, with the park closed for two months. Silver Dollar City is owned by Herschend Family Entertainment. History Marvel Cave Silver Dollar City is situated at the site of one of the Ozarks' oldest attractions, Marvel Cave. Henry T. Blow, a lead mining magnate, explored the cave with six miners. They found no lead, but were convinced that the flat ceiling of one room was composed of marble, they originally named the cave Marble Cave. The cave remained undisturbed until 1882 when a group led by T. Hodges Jones and Truman S. Powell entered the ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Outlaw Run
Outlaw Run is a wooden roller coaster located at Silver Dollar City in Branson, Missouri. Designed by Alan Schilke, Outlaw Run is the first wooden roller coaster manufactured by Rocky Mountain Construction (RMC) and became the first wooden coaster with multiple inversions. It features a drop, three inversions, and a maximum speed of that makes Outlaw Run the sixth-fastest wooden coaster in the world. Its 81-degree first drop is also the fourth steepest in the world among wooden roller coasters. Development of an early concept began in 2009, and Outlaw Run was officially announced in August 2012.

New Texas Giant
New Texas Giant is a steel roller coaster located at Six Flags Over Texas in Arlington, Texas. It originally opened as Texas Giant, which was the tallest wooden roller coaster in the world when it debuted in 1990. Manufactured by Dinn Corporation and designed by Curtis D. Summers, Texas Giant operated for nearly two decades and was ranked in ''Amusement Today'' magazine's annual Golden Ticket Awards as the best roller coaster in 1998 and 1999. The ride's popularity declined as it gained a negative reputation for its increasing roughness. Texas Giant closed in 2009 and underwent an 18-month refurbishment by Rocky Mountain Construction (RMC). It reemerged as New Texas Giant in 2011. Much of the original wooden structure was kept, but the wooden track was replaced with steel using RMC's I-Box track technology.

Steel Coaster
A steel roller coaster is a roller coaster that is defined by having a track made of steel. Steel coasters have earned immense popularity in the past 50 years throughout the world. Incorporating tubular steel track and polyurethane-coated wheels, the steel roller coasters can provide a taller, smoother, and faster ride with more inversions than a traditional wooden roller coaster. Arrow Dynamics first introduced the steel roller coaster to feature tubular track to the thrill industry with their creations of the Matterhorn Bobsleds (Disneyland) in 1959 and the Runaway Mine Train (Six Flags Over Texas) in 1966. As of 2006, the oldest operating steel roller coaster in North America is Little Dipper at Memphis Kiddie Park in Brooklyn, Ohio and has been operating since April 1952. The oldest operating steel rollercoaster in the world is Montaña Suiza at Parque de Atracciones Monte Igueldo (Spain). It has been operating since 1928.

Wooden Coaster
A wooden roller coaster is a type of roller coaster classified by its wooden Rail tracks, track, which consists of running rails made of flat steel strips mounted on laminated wood. The support structure is also typically made of wood, but may also be made of steel latticework, lattice or truss, which has no bearing on a wooden coaster's classification. The type of wood often selected in the construction of wooden coasters worldwide is southern yellow pine, which grows abundantly in the southern United States, due to its density and adherence to different forms of Wood preservation, pressure treatment. Early wooden roller coaster design of the 19th century featured a single set of wheels running on top of the track, which was common in scenic railway rides. John A. Miller introduced side friction roller coaster, side friction coasters and later Underfriction, underfriction coasters in the early 20th century, which added additional sets of wheels running along multiple sid ...

Parabola
In mathematics, a parabola is a plane curve which is mirror-symmetrical and is approximately U-shaped. It fits several superficially different mathematical descriptions, which can all be proved to define exactly the same curves. One description of a parabola involves a point (the focus) and a line (the directrix). The focus does not lie on the directrix. The parabola is the locus of points in that plane that are equidistant from both the directrix and the focus. Another description of a parabola is as a conic section, created from the intersection of a right circular conical surface and a plane parallel to another plane that is tangential to the conical surface. The line perpendicular to the directrix and passing through the focus (that is, the line that splits the parabola through the middle) is called the "axis of symmetry". The point where the parabola intersects its axis of symmetry is called the "vertex" and is the point where the parabola is most sharply curved. The ...
