The Anatomy of a Roller Coaster Essay -- Amusement Parks Rides Essays

The Anatomy of a Roller Coaster To adequately understand the relationship between physics and roller coasters, it is essential to first describe and explain the basic structure of roller coasters. In simple terms, a roller coaster is much like that of a passenger train. To explain, a roller coaster consists of a series of connected cars that move on tracks. However, unlike a train, a roller coaster has no engine, or rather a power source of its own. There are two major types of roller coasters, characterized mainly by their track structure. The tracks of wooden roller coasters are similar to those of traditional railroad tracks, as metal wheels of the roller coaster roll on a flat metal strip that is bolted to a sturdy running track made of laminated wood (How Roller Coasters Work). A majority of wooden roller coasters have the same wheel design as that of a train, where the inner part of the wheel has a wide lip that prevents the car from rolling off the side of the track. Additionally, wooden roller coasters also have another set of wheels that run underneath the track, keeping the cars from flying up into the air. Wooden coaster tracks are braced by wooden crossties and diagonal support beams; the entire track structure rests on an intricate lattice of wooden or steel beams (How Roller Coasters Work). With the wooden roller coaster structure, designers can combine hills, twists, and turns into an infinite variety of course la youts. In wooden roller coasters, however, the exhilarating motion is mainly up and down. The second type of major roller coaster, based on tubular steel tracks, was introduced in the 1950s. Consisting of a pair of long steel tubes, this particular track structure is supported by a sturdy, l... ...), roller coaster designers incorporate tight fits and near misses to create the sensation that the rider is traveling through the structure at out-of-control speeds. In review, in relation to the anatomy, basic workings, and sensations found in roller coasters, physics definitely plays a critical role. More specifically, without the laws of physics, or rather the incorporation of physics, roller coasters would be unknown to the world of entertainment. With the incorporation of physics, roller coaster designers have been able to create better, faster, and more unimaginable thrills with complete accuracy and safety. As mentioned previously, although physics is found in essentially every facet of life, I would like to believe that the majority of entertainment-seeking enthusiasts are grateful that the application of physics isn’t simply restricted to the classroom.

Economic Questions

Because of scarcity, every nation is faced with â€Å"The 3 K eye Economic Questions: Who – consumes the goods & services produced in society? â€Å"For whom? ‘ is a public choice question. All economic systems must determine e which goods and services will be available for public use and which for private use. What -?goods & services should be produced? â€Å"What to produce? ‘ is an allocation question. All economic systems must date ermine how to allocate productive resources in the form of land (natural resources/ raw materials), labor (work for which we earn pay) and capital (human education & job training) (physical buildings, equipment & tools).How – should goods & services be produced? â€Å"How to produce? † is an efficiency question. All economic systems must deter mine how goods and services will be produced. How do different economic systems respond to the 3 Key Economic questions ? First of all, we need to define exactly what an  "Economic System† is: The institutional framework of formal and informal rules that a society uses t o determine what to produce, how to produce and how to distribute goods and services. Another, more popular term for economic system is economy.An economy, o r economic system, is he structural framework in which households, businesses, and governments undertake the production and consumption decisions that allocate limited resources to satisfy unlimited wants and needs. An economic system is primarily characterized by its key institutions, especial y those relating to the ownership and control Of resources and the means Of production. Two realtor economic systems that differ based on key institutions are capitalism and communism.Capitalism is an economic system in which ownership and control is largely in private hands (b genuineness and households), as opposed to public hands (government). One of the key institute actions underlying capitalism is private property rights. Comm unism, in contrast, is an economic system in which ownership and control predominately rests with government. Socialism is a the rid noted economic system that borrows institutions from both capitalism and communism. Economic systems can be categorized according to who makes most Of the De concisions in an economy.Most economies can generally categorized as one of two kinds: ; Market Economy An economy that relies on a system of interdependent market prices to local tee goods, services, and productive resources and to coordinate the diverse plans of con mummers and producers, all of them pursuing their own selflessness. ; Command Economy An economy in which most economic Issues of production and distribution AR e resolved through central planning and control. So, how do different economic systems respond to the three basic economic questions?In a socialist or command system, the central authority determines what, how, an d for whom goods and services will be produced. A Mixed System incorporates elements of both corn and and market systems in determining answers to the three questions. Mixed economies wit h Strong market monuments also include a public goods and services sector, just as command economies like Cuba include a private goods and services sector. In a market economy, most of the decisions in the economy about what to pr educe, how to produce it and who receives it are made by individuals and firms.At the other end of the spectrum: In a command economy, government officials make most of the decisions in t he economy about what to produce, how to produce it and who receives it. Most economic systems also contain elements of tradition or repeating decide ions in ways made at an earlier time or by an earlier generation. Today, nearly all economies are actually mixed, in that some economic decisions are made by individuals and private firms, but some e are also made by government officials, either through rules and regulations or through govern mentored firms. The U. S. Economy leans toward the marionettes side of the spectrum.An economy like Cuba or North Korea is near the command economy side of the spectrum.

Market Economies (â€Å"Capitalism Capitalism is undoubtedly at the top of any list of economic systems operating in the modern world. This system is based on: (1) private appropriative ownership of resource recess and the means of production, (2) individual illiberality freedom on the part of the resource o Wieners to use their resources as they see fit, and (3) competitive markets system of relatively co imitative markets. Ender capitalism, governments establish the basic rules of the game and are responsible for the production of public goods, but the vast majority of resource allocation De concisions are undertaken by individuals, as either consumers or producers. The United States is one of the more noted examp les of capitalism. However, most modern industrialized economies of Europe, Asia, North America, and South America operate under capitalism.Command Economies (â€Å"Socialism†) In theory, socialism is the transition between capitalism and communism and is based on: (1) government ownership of resources and the means of production, (2) worker control of government, and (3) income distributed according to needs. As practiced in the real world, socialism is an economic system based on (1) nationalized intergovernmental ownership and control 01 of key industries and (2) central polycrystalline detailed, but not comprehensive, resound:e local ion decision making by the central government. Ender real world socialism, governments exert extensive control over resource e allocation decisions, primarily involving key industries such as transportation, energy pr deduction, communication, and health care. While Sweden exemplifies modern socialism, several Europe an nations have practiced varying forms of socialism over the decades. Command Economies (â€Å"Communism†) In theory, communism is an economic system based on: (1) a classless society , (2) common ownership of resources, (3) no government, and (4) income distributed accord ins to needs.

Pursuing A Career As An Epidemiologist - 1856 Words

A famous epidemiologist once said â€Å"Epidemiologist is like a bikini: what is revealed is interesting; what is concealed is crucial† (Duesberg). Epidemiology is the study of diseases and informs the public about health epidemics and new health standards put in place. A typical day for an epidemiologist is as follows: they usually work in laboratories, businesses, and offices where they discover many diseases and conduct research while also finding cures for new malignant diseases. Epidemiologist also focuses on medicine for example, they create new antibiotics for vicious diseases or create vaccines to help combat diseases. In order to become an epidemiologist, it would take 4 years as an undergraduate and obtain a Masters in Biology or Public Health. During high school, it is required to take 1 year of Biology and Chemistry or to obtain some kind of science background in order to help me get better prepared. In this paper, I will argue why I selected to pursue a career as an Epidemiologist based on prior knowledge and interest in public health Biology, health epidemics and experiments/case studies. Epidemiology is what advises people of new world epidemics and new health standards worldwide. Epidemiologist are well known for their ideal way to handle and control epidemics of the everyday modern world by conducting research and going through various experiments.
