Expansion and Contraction of Materials When most materials are heated they expand and this increase their volume. One example of expansion is the fitting of the starter ring gear to the flywheel. The gear is heated until it expands sufficiently to pass over the rim of the flywheel, and when it is cool the gear tries to return to its original size, this gripping the flywheel with considerable force. All metals do not expand equally when heated through the same range of temperature, e.g. aluminium
Lab Report Coefficient of Linear Expansion of a Metal Introduction Most solid materials expand upon heating and contract when cooled because it undergoes a change in the energy state of its molecules or atoms. According to the atomic perspective, the average vibrational amplitude of an atom increases as the temperature rises. Each material has a property called ¡§coefficient of linear expansion¡¨ that is indicative of the extent to which a material expands upon heating or contracts when cooling
In 1845, a fellow named John C. Calhoun coined the term "Manifest Destiny." The term Manifest Destiny was a slogan for westward expansion during the 1840's. In the west there was plenty of land, national security, the spread of democracy, urbanization, but there was also poverty out west. People moved out west in search for a new life such as a new beginning. Moving out west, settlers from the east were taking a risk of a lot of things. The climate was different and there were more cultures that
Westward Expansion and Imperialism Throughout most of the nineteenth century, the United States expanded its territory westward through purchase and annexation. At the end of the century, however, expansion became imperialism, as America acquired several territories overseas. This policy shift from expansionism to imperialism came about as a result of American's experience in the Spanish American War and the Congressional debates that followed the American victory. After temporarily resolving
Native American Boarding Schools During the Westward Expansion People know about the conflict between the Indian's cultures and the settler's cultures during the westward expansion. Many people know the fierce battles and melees between the Indians and the settlers that were born from this cultural conflict. In spite of this, many people may not know about the systematic and deliberate means employed by the U.S. government to permanently rid their new land of the Indians who had lived their

Frontier Expansion vs. the American Bison “The wilderness masters the colonist. It finds him a European in dress, industries, tools, modes of travel, and thought. It takes him from the railroad car and puts him in the birch canoe. It strips off the garments of civilization and arrays him in the hunting shirt and the moccasin. It puts him in the log cabin.... Before long he has gone to planting Indian corn and plowing with a sharp stick.... In short, at the frontier the environment is at first

Controlling Environmental Damage Caused by Development and Human Expansion Progress! Progress is something that can not be stopped. Many attempts have been made to limit the amount of human progress and expansion, though development has been halted. The human spirit and instinctive tendency to create and achieve more than those who have come before has created mass environmental damage and destruction along the way. I propose that stricter laws and regulations be created that will reward those
Expansion vs. Preservation William Sonntag was acclaimed in the 1850s as a painter of the dramatic landscape. In his painting “Garden of the Gods,” Sonntag portrays a family in the time of the westward expansion. The very subtle painting, expressed by its loose brushwork, captures the shifting atmospheric contrasts of light and dark. Apparent in the painting is a family struggling to survive in nature. In the bottom left corner of the painting is a weather beaten shack, the home of the struggling
The Louisiana Purchase of 1803 started the Westward Expansion. There were many benefits from the purchase for the US that the French didn’t realize before they sold it. The purchase gave the US access to the Mississippi river which allowed for expansion of river trade to the North and South from the center of the US. The port city of New Orleans was bought by the US and its prosperity benefited the US greatly. The US sent Louis and Clark west to investigate the purchase. They were secretly told
In the twenty-five years between 1865 and 1890, the miles of railroad track in the United States increased from 35,000 to 200,000. The enormous increase in track produced a boost in America's economy. The farming economy was greatly helped by the expansion of the railroad system, which became one of the main and most efficient ways to transport farmers' produce. This was especially helpful to farms in remote locations. The expanded railroad system enabled farmers to produce more crops because of the
Title IX and the Expansion of Educational Rights for Women Title IX legislation, passed in 1972, expanded the rights of an individual in ed ucational opportunities. It equalized academic prospects for individuals by ensuring that males and females must have equal access to educational possibilities. Title IX is traditionally attributed to the growth of athletic programs for women by demanding that programs for women are given the same amount of money and attention as men's teams. However, Title
Expansion of Government Power During the Civil War and Reconstruction Contrary to what I believed in the past, the United States federal government retained and expanded their power and authority during the years of the Civil war along with the period of Reconstruction. Through drafts and monitored elections, they exercised this power during the Civil War. Then, as Reconstruction began, they initiated other methods of increasing their authority over the citizens. Military was placed in Southern
Problems with the Expansion of NATO Throughout the Clinton years the government has tried to make NATO expansion look like a risk free operation. But the truth is that there are many risks and dangers that go with the expansion of NATO. It has been said that the expansion of NATO would be a fatal error in the American policy. As NATO expands it is drawing an imaginary dividing line separating the many NATO nations from the Ukraine, Russia and other countries in the eastern half of the world. The
numerous people were affected in many facets of life. This all means that progress is awsome to achieve, but when achieved, people have to realize the process they had to do to achieve it, which was stepping on other people to get there. Westward expansion was the greatest method to achieve the grouping of the natural resources found and use them as needed. To gain access to the western part of the country the white settlers had to pass through the Native Americans. While pushing westward the white
Treatment of Change and Expansion in Lotos-Eaters and Rip Van Winkle During the Victorian Era, great accomplishments lead to prosperity for the British Empire. Accomplishments include owning nearly a quarter of the world’s land and its people. As a result, trade and commerce expanded, and Great Britain reached the height of its power. Furthermore, science rapidly made progress during this time. These rapid strides in economic and technological advances gave the British people a feeling of pessimism

Imagine spending twenty-four years in prison for a crime you did not commit. Furthermore, imagine that conviction is based on witness testimony and no valid forensic evidence. This is the case for Texas resident Steven Phillips and countless others whose unfortunate circumstances stem from the fallacious nature of human memory. Phillips was wrongly convicted in 1982 based on a few of the many inadequacies of human memory (“Know the Cases”). Unfortunately, this is an all-too-common occurrence due
I believe that time is a gift from God and it is up to individuals to make wise decisions regarding how they will invest the time that God has granted them. My perception of time dictates, to a degree, how I chose to use it. I believe that time is linear - there is a beginning and an end - God, the creator of time. For this reason, I strive to use my time wisely. One day I will be unable to live like I do now, so I believe that it is important to make the most of what time I have. However, I also
