Physics of Boomerangs - 638 Words

Boomerangs are one of the first throwing machines invented by humans. Boomerangs first developed as an improvement of the carved throwing sticks. Usually made of wood and they were banana shaped; both arms were carved into curved surfaces. Typically 3 ft long and weighing 5-10 lbs. they were effective hunting tools. When thrown, boomerangs traveled parallel to the ground as far as 650 ft The physics of a Boomerang can be broken down into three simple reasons: 1. A boomerang has 2 arms or wings, similar to airplane wings, which created lift. 2. In flight, the top rotates in the directions of the boomerang and the bottom rotates in the opposite direction– creating an uneven lift and tilting, which is prevented by torque 3. The torque doesn’t flip the boomerang over, but instead creates angular momentum or gyroscope precession. 1. The boomerang’s arms being shaped like wings are very important. Each wing has both a flat side and a curved side, like an airplane wing. The purpose of the design is to create an airfoil shape therefore creating lift. This lift is created when the thrower thrust the boomerang; that air foils deflects the air down which in return propels the wing up. The air being pushed to the underside of the wing creates 1/3 of the lift of a wing. So if the boomerang doesn’t have a strong airfoil shape, it will not have enough lift to overcome the downward pressure. As the air is moving across the airfoil it has to go farther on the curved surface than it does onShow MoreRelated The Physics of Boomerangs Essay1379 Words   |  6 PagesThe Physics of Boomerangs The successful flight of a boomerang looks as though it never should happen. Its more or less circular flight path comes from the interaction of two physical phenomena: the aerodynamic lift of the arms of the boomerang and the spinning boomerang’s maintenance of angular momentum. Briefly put, the airfoil at the boomerang’s forward rotating edge provides more lift than its rearward rotating edge. This elevates one side of the boomerang. The spinning object maintainsRead MoreCompare And Contrast Batman Of Dc And Iron Man925 Words   |  4 Pagesintellect and enormous amounts of money to create technology for their powers.

The Academic Writing Processes Is The Second Strategy For...

One of the academic writing processes is pre-writing. Pre-writing has two strategies; one of the strategies is invention strategies. The invention strategies is an organizer that presents strategies for â€Å"inventing† ideas or details that may be organized and developed in an essay or in a writing form. An example is brainstorming; this technique is the process of rapidly listing or developing information about a topic. As you brainstorm the ideas, do not worry whether they are bad or good. Another example is clustering; this is a way of mapping out ideas to show their relationship. Write the topic in the center of the page, think of details that can relate to the topic and connect the details around the topic with lines. Organization strategy is the second strategy for pre-writing. Once you have used the invention strategies to develop the ideas about your topic, you may need to use a different set of organizers to help organize those ideas. In the organization strategy, t here are two organizations one of them is graphic organizers. This style visualizes the ideas and their relationships to another. An example of graphic organizers is a Venn diagram; which is used to make comparisons. The other organization is formal outline; this is an organization of information or ideas that can be used for writing a draft. It is important that logical order is used when using an outline and also items should be closely related, and placed together for a more natural flow of ideas.Show MoreRelatedManipulating Mind-Mapping Software to Develop Essay Writing1665 Words   |  7 Pagesexperiences through writing.

Questions: I. Technical and factual information Ii. Formal analysis sculpture and architecture provide a general description of the object or building in the first paragraphA. (for sculptural object only) type of sculpture: is it low relief; high relief; a free standing figure; a group of figures; a combination of these?B. Material and techinical means: is the sculpture/building crafted out of wood, stone? (for sculpture only, is the object modeled in clay, wax, then cast in bronze?) Has the artist left traces of the tools used in carving of modeling the object on the surface (chisel, fingerprints, etc.)?C. Volumes: what kind of volumetric forms are basic to the sculpture/building? Geometrical ones: conical, cubic, or pyramidal? Irregular ones: jagged, smooth, organic?D. Structure: how are these forms organized? Be specific. What? Where exactly?E. Line: how is line used in the sculpture/building? Does the piece have an open or closed silhouette? Are the dominant linear elements seen in the for ms themselves, or are they incised onto the surfaces of the forms? Is there a conflict between the linear and volumetric elements?F. Space: to what degree does the object/building displace space? Do the forms and space interpenetrate? If it is a relief sculpture, does it create its own illusion of space within it? Is recession into depth or projection into the beholders space suggested? Is the object/building meant to be seen from a particular point of view? Is it frontal? Does it turn in space does it change as you walk around it? How? Can its composition be understood from one viewpoint only? From any viewpoints?G. Color: is color added to the sculpture/building (by means of paint, inlaid gems, etc.) Is the color of the material itself important? Does this color possess a special meaning? Does it have a descriptive or expressive function?H. Light: has the artist considered the effect of light upon his work? Are the forms arranged so that a particular effect of light and shade will be attained?I. Textures: what is the texture of the surface? Is it bumpy? Smooth? Does the artist vary textures to enhanced aspects of the composition? What? Where? Why?J. General observations: are there specific symbolic evocations in the work? What, where, why? Does the sculptural object fit into the environment successfully?If it is a building, how does the environment support or detract from the overallsuccess of the building? Answers: I. Technical and Factual Information: The Lexington Minuteman statue is the symbol of warrior. Minutemen were a group of people who prepared a militia group during the American Revolution. They were trained to use any kind of weapons. In Lexington Minuteman it represents John Parker, a leader of this group. The statue was sculpted by Henry Hudson Kitson and placed in the year of 1900 (Galvin, 1989). Although there is confusion on the sculptor as somebody says Daniel Chester French was the sculptor. The statue is being sophistically preserved which helps in managing the access of the statue. II. Formal Analysis: A. Type of Sculpture: In order to identify the type of the sculpture, Hood (1960) seems to have opined it is a free standing statue which helps in development of the structural ethos. The statue is the perpetual figure of low relief. B. Material and Technical Means: It is made of bronze and has been concretized latter on. The statue portrays John Parker standing erect holding a musket in his hand putting on the leg, slightly advanced. Basically, john Parker was a farmer turned soldier in order to protect the national pride. Rigidity and robustness of the statue is significantly noticeable. C. Volumes: The volume of the statue is quite intense. From the geometrical point of view the statue is cubic in nature having smooth body in its portrayal. Defining the statue having a sufficient volume of sophistication it projects an ethnic look. D. Structure: The stature can be spotted in the southeast corner of Battle Green by facing the route of arrival of British force. In the basement of the statue the stone platter can be seen. Richard (2004) has stated that the statue to $10,853 to be build up. As farmers were becoming warriors in that period to protect the British evasion, the structure was needed to be rigid in its nature. This form of the stature is really intrinsic in the approaches which help in developing a convergence. E. Line: The liner approach is literally sophisticated which engages in open silhouette. It helps in managing the surface of the stature as well. Garry (1999) seems to have stated that there is no difference between the linear and volumetric elements. The surface of the forms is also intrinsic in nature which helps in giving a sculptural potentiality. F. Space: The stature suggests heroism and an ethnic sophistication. The statue is having an in depth and informal approach which targets at ensnaring the viewers attraction in one look (Sherman and Hood, 2012). As one walks around the statue, he or she can feel the thrill by witnessing the outlook of the statue. G. Color: The color of the sculpture is brass orientation. The color has been made of this type because it has an intricate meaning. It expresses that how a soldier battles with so many complexities and difficulties. H. Light: The idea of the artist is to give an intense look for this structure. Under the sun it looks bright and in absence of the sun it looks complete black. I. Texture: Within the stones underneath of the stature, there is a written plaque which reads: The Bequest Of Francis Brown Hayes To The Town Of Lexington Erected 1899 (Staicu, 2010). It is completely smooth in the composition. J. General Observation: The structure is environmentally free and is supported within all the seasons. The structure is intrinsic in the approach.

Market Structure during Post

The words Capitalism and Socialism are distinct in usage and have been used in the Maoist regime and the Reform Era, which is commonly known as the post-Mao regime. This happened after the death of Mao in September 1976. Deng, the chief architect of change who explicitly rejected Mao’s â€Å"politics in command† which brought about certain undesirable aspects such as the Great Leap Forward and the Cultural Revolution replaced it.Advertising We will write a custom essay sample on Market Structure during Post-Mao China: Capitalism or Socialism? specifically for you for only $16.05 $11/page Learn More His economic objective was to do away with the all the aspects that made China poor especially peasant backwardness. One of the key economic sectors that needed to be reformed were national defense, agriculture as well as science and technology. The aim of this change is to transform China into a socially and economically highly developed country within the next 30 to 50 years. China is no doubt in a capitalistic economy after going through an unsatisfactory â€Å"halfway house† which was neither capitalism nor socialism that brought about bureaucratic intrusion in the economy. This yielded very poor results in the economy. The Chinese economy has seen undergone a sweeping economy. Most of China’s retail stores and service shops are currently under private ownership. Privatization of property has also extended to other sectors such as the real estate and the agricultural sectors. This has led to the permeation of a great sense of division of labor in the agricultural sector. Despite the increasing trend of the cost of living in China, a great proportion of the Chinese population appreciates the freedom of choice within the Chinese markets. Most of the retail stores offer a variety of products with varying consumer friendly prices. The communist ties of the Chinese community have lost their strong ties paving w ay for a new approach to the economic affairs of the nation. This has led to a great improvement in the standards of living for most of the citizens especially those are not financially stable. In the traditional setting, capitalism refers to the control of the means of production in an economy by the affluent class- capitalists. The class of capitalists is able to control a large proportion of a nation’s economy because of the favors they receive from the political system in the country in question. In the contemporary society, it refers to the privatization of the means of production in a country’s economy. On the other hand, socialism refers to the phenomenon whereby the ownership as well as the major means of production is under the control of the state. All the people in the society have substantial control over the available means of production. It is applied to an economic system in which property is held in common and not individually and a political hierarchy governs the most important relationships within the economic system.Advertising Looking for essay on political sciences?

One of the major changes is the increase in the gap between the rich and the poor in the Chinese community. The housing market and consumerism have undergone drastic changes in the recent past. Additionally, most of the economic sectors have undergone privatization. There has been an increase in the number of people in the Chinese community as well as a similar increase in the number of the affluent in the society. The poor are getting poorer whereas the rich continue amassing wealth. Capitalism makes it hard for the Chinese people to adapt and live to tell the tale. It makes it hard for the people to identify with what they were used to such as their traditional culture, family background and ones surname. In essence , identity of the majority in the Chinese population is continually becoming a problem. Today, socioeconomic status and the struggle to be rich are choking them to death for the mere purpose of identity in the society. It is very clear that while some are gaining, others are losing pushing socioeconomic classes in opposite directions. Getting a job has become a painful experience for many unlike before where people had work units. Most of the jobs are under privatization. Much effort is on the peoples’ abilities to produce quality products and work effectively. They are now competing to get a job and finding new identities as they work on their own, which proves to be vicious and difficult. Greed too has changed the way people relate and conduct their lives. Due to the hardships associated with the capitalist market, many people have to work for longer hours to be able to access most of the basic consumer products. During the Mao regime, the people measured their wealth in te rms of children, land as well as their homes. They also acted as a form of their identity. The earlier Chinese population would know ones socioeconomic status and their identity if they mentioned where they lived. This too changed during post-Mao era where housing was privatized. â€Å"The demise of public housing regime and the rise of commercial real estate industry have opened up new opportunities for the people in the urban centers to seek differentiated lifestyles, status recognition and cultural orientations† (Zhang, 2008, 24).
