6 Kinds of Simple Machines

6 Kinds of Simple Machines Work is performed by applying a force over a distance. These six simple machines create a greater output force than the input force; the ratio of these forces is the mechanical advantage of the machine. All six of the simple machines listed here have been used for thousands of years, and the physics behind several of them were quantified by the Greek philosopher Archimedes (ca. 287–212Â  BCE). When combined, these machines can be used together to create an even greater mechanical advantage, as in the case of a bicycle. Lever A lever is a simple machine that consists of a rigid object (often a bar of some kind) and a fulcrum (or pivot). Applying a force to one end of the rigid object causes it to pivot about the fulcrum, causing a magnification of the force at another point along the rigid object. There are three classes of levers, depending on where the input force, output force, and fulcrum are in relation to each other. The earliest lever was in use as a balance scale by 5000 BCE; Archimedes is credited with saying Give me a place to stand and I will move the earth. Baseball bats, seesaws, wheelbarrows, and crowbars are all types of levers. Wheel Axle A wheel is a circular device that is attached to a rigid bar in its center. A force applied to the wheel causes the axle to rotate, which can be used to magnify the force (by, for example, having a rope wind around the axle). Alternately, a force applied to provide rotation on the axle translates into rotation of the wheel. It can be viewed as a type of lever that rotates around a center fulcrum. The earliest wheel and axle combination known was a toy model of a four-wheeled cart made in Mesopotamia about 3500 BCE. Ferris wheels, tires, and rolling pins are examples of wheels and axles. Inclined Plane An inclined plane is a plane surface set at an angle to another surface. This results in doing the same amount of work by applying the force over a longer distance. The most basic inclined plane is a ramp; it requires less force to move up a ramp to a higher elevation than to climb to that height vertically. No one invented the inclined plane since it occurs naturally in nature, but people used ramps to build large buildings (monumental architecture) as early as 10,000–8,500Â  BCE. Archimedess On Plane Equilibrium describes the centers of gravity for various geometrical plane figures. Wedge The wedge is often considered a double inclined plane- both sides are inclined- that moves to exert a force along the lengths of the sides. The force is perpendicular to the inclined surfaces, so it pushes two objects (or portions of a single object) apart. Axes, knives, and chisels are all wedges. The common door wedge uses the force on the surfaces to provide friction, rather than separate things, but its still fundamentally a wedge. The wedge is the oldest simple machine, made by our ancestors Homo erectus at least as long ago as 1.2 million years to make stone tools. Screw A screw is a shaft that has an inclined groove along its surface. By rotating the screw (applying a torque), the force is applied perpendicular to the groove, thus translating a rotational force into a linear one. It is frequently used to fasten objects together (as the hardware screw and bolt does). The Babylonians in Mesopotamia developed the screw in the 7th century BCE, to elevate water from a low-lying body to a higher one (irrigate a garden from a river). This machine would later to be known as Archimedes screw. Pulley A pulley is a wheel with a groove along its edge, where a rope or cable can be placed. It uses the principle of applying force over a longer distance, and also the tension in the rope or cable, to reduce the magnitude of the necessary force. Complex systems of pulleys can be used to greatly reduce the force that must be applied initially to move an object. Simple pulleys were used by the Babylonians in the 7th century BCE; the first complex one (with several wheels) was invented by the Greeks about 400 BCE. Archimedes perfected the existing technology, making the first fully-realized block and tackle. Whats a Machine? The first use of the word machine (machina) in Greek was by the ancient Greek poet Homer in the 8th century BCE, who used it to refer to political manipulation. The Greek playwright Aeschylus (523–426 BCE) is credited with using the word in reference to theatrical machines such as the deus ex machina or god from a machine. This machine was a crane that brought actors playing gods onto the stage. Sources and Further Reading Bautista Paz, Emilio, et al. A Brief Illustrated History of Machines and Mechanisms.

Report on foreign language film - Research Paper Example The movie revolves around a young Polish boy whom Visconti uses to incarnate beauty. He is a 14-year-old boy named Tadzio, played by Swedish Bjà ¸rn Andresen. The boy’s mother is played by Silvana Mangano, a beautiful Italian actress. Tadzio, the longhaired blond boy is the focus of attention of Gustav Von Aschenbach (Dirk Bogarde). An obsession of the boys beauty by Aschenbach leads to the question on the nature of the admiration (Andre 34). The main question in the movie is whether it is ethically okay in the moral standards or not. There is the mystery behind the movie in its structure and style, its symbolism and politics owing much of these to the novel by Thomas Mann’s with the same title Death in Venice, which the movie is based on. The movie is largely silent, in performance, and the actor Bogarde delivered an enlargement of meaning. The romantic suffering of Von Aschenbach manifested by his passion for Tadzio, emotional suffering on the death of his daughter. Setting Von Aschenbach on a journey of creation of beauty and purity discovered in Tadzio. The cinematography by Pasquale De Santis is also depicted in the movie. Scenes are well framed; there are lots of camera spinning from left to right allowing the observation of secondary characters. Costumes are highly stylized, and convey a Victorian look and feel, (Can 18). Can continues by making analysis on the soundtrack, which he says are echoes of one of Mahler melodies; the Adagietto of the Fifth Symphony. According to Snowball, Visconti overdid many things in the movie, which is quite evident at the end with the death of Aschenbach. He feels the movie become very boring toward the end but only saved by lovely things on the periphery. According to Snowball, he movie represents a deadly pestilence threatening both physically and represents the corruption that compromises and threatens all ideals. James feels that the Death in Venice was

Final Review - Assignment Example a. In his book, Momaday has brought up a unique platform and from this one can view the cultural history of the Kiowa people. Through this book, Momaday has been able to bring out his own sense of background. The book has been structured to bring out a sense of purpose for Momaday who is a Kiowa Indian in the sense that he was born of that origin. Though he was born into that culture, he received his education in the American way. The book is structured to bring out the ancestral heritage of the Kiowa Indians, and in his own way he has constructed this in his book through the dominant culture, his own memory of the events and also, his imagination so that the structure of the book can come out right. He has managed to bring out the origin of the Kiowa people, their development of their own culture and how they still exist up to date. He has managed to carry on the mantel of their tradition (Momaday, 45). b. The way to the rainy mountain is a book written by Momaday who tells of his a ncestor’s, the Kiowa Indians and their origin, their cultures and tradition and also how they still exist today through imagination and through writing about them (Momaday, 12). The genre of this book is Folklore, which basically means that it mainly consists of legends, oral history, jokes, proverbs, popular beliefs, stories and customs. The absolutely true diary of a part time Indian is a book about a young Indian who grew up on a reservation and decided to go to a white school where he starts being treated as an outcast. The book tells of his struggle to gain his status both in school and at the reservation. The genre of this book is young-adult fiction in that it is one targeted for adolescents and young adults (Sherman, 14). c. Wampum can be described as the sacred shell beads that were traditionally used by the Eastern Woodlands tribes. These were the indigenous people of North America. They were at times used as currency during the colonist’s period. They were s ignificant in terms of being used as a symbol for tradition like in marriages. Some of the uses include being used to mark exchanges such as in marriages, engagements and also agreements in terms of betrothal. Question 2 Historical events would likely to have been interpreted from a Native American point of view rather than an Anglo American point of view because in the real sense, Native Americans were the initially the inventors of most traditions and those traditions still exist and thus, their experience is much more exhibited. Native Americans and their history have become the interest of many people, both Indians and non-Indians alike. There is an interesting fact about discussing the history of Indians and thus it brings out an informative and appealing manner to their history (Mary, 22). a. When the congress unilaterally decided to stop making treaties with the Native Nations and forced assimilation, there were many effects and affects that followed. There was the assassinat ion of resistance leaders and also some of the leaders were separated from their people and imprisoned in certain remote facilities like Fort Marion. Geronimo was among those imprisoned (Geronimo, 45). b. The Native Americans would classify the
