Origins America at the turn of the century was booming with new life and new opportunities. With rapid growth of population, big businesses, and consuming added with the pressure of immigration and labor laws the country was at the brink of bursting. It wasnt hard to tell that America was looking to expand its borders. Don’t waste time! Our writers will create an original "American Imperialism" essay for you Create order As agriculture and factories improved productivity, they were able to make a greater abundance of products and began to look to expand their markets. But these resourceful reasons were not the only thing that started the expansion. Many people inspired americans to push for an expansion. One example is Reverend Josiah Strong who preached that it was religious americans duty to spread their gospel to other nations. Other examples are Aggressive Americans such as Henry Cabot Lodge and Theodore Roosevelt whose belief in social darwinism led them to believe that since America was the fittest and strongest nation, it deserved the earth. Others in nations across the world believed the same causing Europe in 1880 to explore uncharted Africa and in 1890 many other powerful countries took land from China pressuring the U.S. to keep up (Kennedy Cohen, 2016). Impact Imperialism shaped our world today in both positive and negative ways. Some examples of positive impacts are an increase in trade, new technology, educational and medical advancements. America signed Bilateral Economic Treaties which opened doors for trade and involved countries with American business. Some of the countries involved with these treaties were Cuba, Colombia, the Dominican Republic, the British West Indies, Mexico, El Salvador, and, Spanish-dominated Puerto Rico. These countries would export raw goods to the U.S and in return would receive Americas Manufactured goods. (Raymer, 2014). Often times America came in to the country bringing with it new technology that changed the society, such as telegraphs and printing presses. Americans set up road and canal systems along with industrial farming methods increasing the amount of product yielded from local workers. Missionaries also entered new american territories, they educated children and set up schooling systems along with giving medical aid and improved local sanitation ( Muscato, 2003). These all, in theory, improved the way of life for the newly annexed. But in addition to these seemingly positive outcomes there were some extremely negative effects as well. Often times civilizing natives meant forcing a new way of life upon people who had different cultures and beliefs rather than giving them a better life. Natives were often exploited for cheap labor and left to do grueling hard physical labor. They worked long hard hours on fields that were once their own and received little in return. In addition to economic injustices they were also severely discriminated against, as missionaries flocked into the newly annexed land forcing natives into a new religion and to do away with their own cultural beliefs. Congress cared little for the rights of these natives and did little to make sure they were being treated reasonably and fair. Although America was reaping the benefits of their land, the annexed did not get to enjoy the blessings of America. Impact on America America reaped multiple benefits from their Imperialistic feats. One main benefit was the economic growth they experienced. As they expanded their markets foreign trade became a key part in economic successes. As of the 1900s America made $1.5 billion in exports and by 1914 10% of all American made products were being shipped overseas (Raymer, 2014). Countries such as Mexico and Cuba began to rely on America. Mexico during 20th century relied on the U.S. for over half of their oil supply and Cuba relied of U.S. for much of its manufacturing, exporting nearly all of their sugar, a staggering 90% (Raymer, 2014) This gave the U.S. economic power over many countries helping them eventually become a world power. America also with their increase in land was able to establish a more powerful naval and military empire. With newly annexed Hawaiis Pearl Harbor and Cubas Guantanamo Bay the U.S. had two new ocean access military bases. Americas immense military force not only assisted in our imperial agenda but in our eventual rise becoming a world power as well. Conclusion American Imperialism in the 20th century had a broad impact not only on America but on the world. It expanded economies, increased trade, and brought both good and bad results to countries that were annexed but there is no doubt that America left its footprint on the annexed. The imperialistic views of America and their ability to effect the land around them through trade and military power set the stage for america to become the world power it is today.

Gangs Have A Long Negative History Essay - 1479 Words

Gangs have a long negative history. Usually joining a gang is a bad thing to do. Well depending what kind of gang it is, but most of the time it’s been viewed like a violent or a rebellion act. Gangs have had an impact in society for a long time in many different places in the world, and there are a lot of types of gangs. They impact society by increasing the rates of murders, school drop outs, and drug and alcohol abuse. There are many reasons why people join gangs. Some people might join a gang because they’re living in the dangerous side of town or city. They might feel safer being in a gang then not for that sense of protection from fellow gang members. Others seem to join gangs due to peer pressure from others or to have a sense of fitting in somewhere and getting loyalty and respect. Another reason one might join is the need of money. Gang banging has been seen as a way to gain currency and possessions in the past. Gangster rap really impacted gangs over America w hen it first came out. Drug dealing has a lot to do with gangs too but we’ll get to it. There are all types of gangs out there in America but question is. What were the first gangs and where’d they start? In the 1920’s Hispanic gangs began forming in California. They started as smaller groups coming together for unity and socializing in the barrios or neighborhoods where they share same culture, customs, and language. Gang members started as young as 14 year-olds.

Superior Court Observation Free Essays

Business Law 115 Superior Court Observation The Superior Court session I observed was an alcohol impairment case. The defendant in this case, had been found guilty in District Court, but had filed an appeal to the District Court’s decision. The morning began with the juryselection process. We will write a custom essay sample on Superior Court Observation or any similar topic only for you Order Now The potential juror pool began with approximately 30 people. The Clerk of Court, Wendy Williams,drew twelve names at random form a bowl to begin the selection process. Once the initial twelve names were pulled, both attorneys had the opportunity to â€Å"interview† thepotential jurors. The prosecution attorney, Emily Cowen, began the process by asking each person to givesome general background information on themselves. This information included where they were from, how long they had lived in the Hendersonville area, their maritalstatus, occupation, etc. After getting this information, the prosecutor asked questions, such as: Did they feel they could hear the case and form an unbiased opinion? Had they ever served on a jury in the past? Had they ever had any negative experiences with any law enforcement officer? Other questions were asked more specifically referring to the DUI, such as: Did they have any family or friends who had been charged with DUI? The defense attorney, J. Michael Edney, then had the opportunity toask his questions. His questions had an emphasis on items such as whether they had a problem with alcohol use, etc†¦ After the initial questioning, three potential jurors were dismissed. One was dismisseddue to being a past victim of a drunk driver. The second was dismissed due to religious beliefs and the third was dismissed by the prosecutor for reasons that were not obvious to an observer. The Clerk of Court drew three more names from the bowl and those potential jurors were basically asked the same questions as the initial twelve. Of this group of three, the defense attorney dismissed two. The first was apparently dismissed because his brother had multiple DUI convictions. The reason for the second dismissal was not obvious. The Clerk of Court then drew two more names. These two potential jurors were questioned in the same manner and accepted by the attorneyson both side. After the jury of twelve was seated, the process was repeated to find an alternate. The purpose if the alternate was to step in if, for any reason, any of the jurors could not serve during the whole trial. The remaining jury pool was excused from the courtroom. The attorney for the Prosecution began with her opening statement, followed by the defense attorney. The prosecution called the first witness, an officer with the Henderson County Sheriff’s Department. The officer was sworn in and then questioned by the Prosecutor about the events of the night when the defendant was placed under arrest. The defense attorney then cross-examined the witness, followed by a prosecution re-direct and then a defense re-cross examination. The witness was then excused. What struck me during the questioning were the actions of the judge. He sat with his head resting in his hand, almost like he was sleeping. However, he did not miss a beat when an objection was made. He either quickly sustained or over-ruled the objection without even raising his head. At this point in the proceedings, the judge called for a lunch recess. He instructed the jury of six rulesto follow during breaks, briefly these were: They were not to discuss the case amongst themselves. They were not to discuss the case with anyone else outside the courtroom. There should be no formation of an opinion until deliberation. They are not to communicate with anyone involved with the case. They should not read or listen to any media coverage about the trial. Lastly, if applicable, there should be no visitation of the crime scene or no independent inquiry. He explained that any violation of these rules would be considered contempt and punishable as so. After the recess, the prosecution called two more witnesses, another Sheriff’s deputy and an officer with the Highway Patrol. They were both questioned by the prosecution, then the defense. Both were also faced with a re-direct and a re-cross. The witnesses were excused after theirtestimony. At this point, the prosecution rested its case. The defense than began theircase presentation. The defense called the defendant to the stand to testify on his own behalf. After his initial testimony, he was cross-examined by the prosecution. There was no re-direct or re-cross. The defense rested their case. The jury was then sent out of the courtroom so the charge conference could take place. This process involves discussions the prosecution and defense as to which instructions would be given to the jury. There is a large set of written instructions and they discussed which are relevant to the case and would be provided to the jury. Once this was completed, the jury was called back into the courtroom and given instructions on the closing statements. These instructions were the same as they were for the opening statements. The defense gave his closing statement first, followed by the prosecution’s closing statement. The judge then instructed the jury on proper application of the law. He stated that if the prosecution did not prove its case beyond a reasonable doubt, then they must find the defendant not guilty. However, if they did prove their case, the jury must find the defendant guilty. He also instructed the jury on the items agreed upon during the charge conference. The jury then retired to the deliberation room. At this point, the alternate juror is excused. While the jury was deliberating, I observed a conversation between the two attorneys and some other attorneys that happened to be in the courtroom. The prosecutor made the comment that the defendant admitted he had been drinking and that was basically the whole of the case. To that, the defense attorney relied, â€Å"The truth is irrelevant. † I found that statement quite surprising and it has stuck with me, I think, more than any other information. The jury did not come back with a verdict by the end of the day. When I called the Clerk of Court office the following morning, I was told that they had come back at around 10:30 am with a guilty verdict. How to cite Superior Court Observation, Essays

Properties of Engineering Materials free essay sample

Engineering materials Choice of materials for a machine element depends very much on its properties, cost, availability and such other factors. It is therefore important to have some idea of the common engineering materials and their properties before learning the details of design procedure. Common engineering materials are normally classified as metals and nonmetals. Metals may conveniently be divided into ferrous and non-ferrous metals. Important ferrous metals for the present purpose are: (i) Cast iron (ii) wrought iron (iii) steel. Some of the important non-ferrous metals used in engineering design are: (a) Light metal group such as aluminum and its alloys, magnesium and Manganese alloys. (b) Copper based alloys such as brass (Cu-Zn), bronze (Cu-Sn). (c) White metal group such as nickel, silver, white bearing metals e. g. Selection criteria for engineering materials The selection of material, for engineering purposes, is one of the most difficult problem for designer. The best material is one which serves the desired objective at the minimum cost. The following factors should be considered while selecting the material: 1. Availability of the materials. . Suitability of the materials for the working conditions in service. 3. The cost of the material. 4. Its susceptibility to corrosion. 5. Its physical, chemical as well as thermal stability. 6. Material must withstand service demands. Such as dimensional stability, adequate strength, toughness, thermal conductivity etc. 7. The extent of the stresses induced. 8. Factor of safety desired. 9. The initial stresses during the material processing. 10. Its density, melting point, boiling point at the working conditions. 11. The extent of surface finish required. 12. Fabrication requirement. 13. Ease of joining, repair by welding etc. 4. Disposability and recyclability. 15. The aesthetics of the material. 16. Chemical nature of the material. 17. Environmental conditions. Mechanical properties of engineering materials Elasticity This is the property of a material to regain its original shape after deformation when the external forces are removed. All materials are plastic to some extent but the degree varies, for example, both mild steel and rubber are elastic materials but steel is more elastic than rubber. Plasticity This is associated with the permanent deformation of material when the stress level exceeds the yield point. Under plastic conditions materials ideally deform without any increase in stress Strength It is the ability of a material to resist deformation. The strength of a component is usually considered based on the maximum load that can be borne before failure is apparent. If under simple tension the permanent deformation (plastic strain) that takes place in a component before failure, the load-carrying capacity, at the instant of final rupture, will probably be less than the maximum load supported at a lower strain because the load is being applied over significantly smaller cross-sectional area. Under simple compression, the load at fracture will be the maximum applicable over a significantly enlarged area compared with the cross-sectional area under no load. Ductility It is more commonly defined as the ability of a material to deform easily upon the application of a tensile force, or as the ability of a material to withstand plastic deformation without rupture. Ductility may also be thought of in terms of bend ability and crushability. This is the property of the material that enables it to be drawn-out or elongated to an appreciable extent before rupture occurs. The percentage elongation or percentage reduction in area before rupture of a test specimen is the measure of ductility. Normally if percentage elongation exceeds 15% the material is ductile and if it is less than 5%the material is brittle. Lead, copper, aluminium, mild steel are typical ductile materials. Ductile materials show large deformation before fracture. The lack of ductility is often termed brittleness. Usually, if two materials have the same strength and hardness, the one that has the higher ductility is more desirable. The ductility of many metals can change if conditions are altered. An increase in temperature will increase ductility. A decrease in temperature will cause decrease inductility and a change from ductile to brittle behavior Malleability Where ductility is the ability of a material to deform easily upon the application of a tensile force, malleability is the ability of a metal to exhibit large deformation or plastic response when being subjected to compressive force. It is a special case of ductility where it can be rolled into thin sheets but it is not necessary to be so strong. Lead, soft steel, wrought iron, copper and aluminium are some materials in order Of diminishing malleability. Uniform compressive force causes deformation in the manner shown in Figure 7. The material contracts axially with the force and expands laterally. Restraint due to friction at the contact faces induces axial tension on the outside. Tensile forces operate around the circumference with the lateral expansion or increasing girth. Plastic flow at the center of the material also induces tension. Therefore, the criterion of fracture (that is, the limit of plastic deformation) for a plastic material is likely to depend on tensile rather than compressive stress. Temperature change may modify both the plastic flow mode and the fracture mode. Toughness The quality known as toughness describes the way a material reacts under sudden impacts. This is the property which enables a material to be twisted, bent or stretched under impact load or high stress before rupture. It may be considered to be the ability of the material to absorb energy in the plastic zone. The measure of toughness is the amount of energy absorbed after being stressed upto the point of fracture. It is defined as The work required to deform one cubic inch of metal until it fractures. Toughness is measured by the Charpy test or the Izod test. Both of these tests use a notched sample. The location and shape of the notch are standard. The points of support of the sample, as well as the impact of the hammer, must bear a constant relationship to the location of the notch. Hardness Hardness is the property of a material that enables it to resist plastic deformation, penetration, indentation, and scratching. Therefore, hardness is important from an engineering standpoint because resistance to wear by either friction or erosion by steam, oil, and water generally increases with hardness. Several methods have been developed for hardness testing. Those most often used are Brinell, Rockwell, Vickers, Tukon, Sclerscope, and the files test. The first four are based on indentation tests and the fifth on the rebound height of a diamond-tipped metallic hammer. The file test establishes the characteristics of how well a file takes a bite on the material. Creep When a member is subjected to a constant load over a long period of time it undergoes a slow permanent deformation and this is termed as â€Å"creep†. This is dependent on temperature. Usually at elevated temperatures creep is high. Resilience This is the property of the material that enables it to resist shock and impact by storing energy. The measure of resilience is the strain energy absorbed per unit volume. For a rod of length L subjected to tensile load P, a linear load-deflection plot is shown in figure- Brittleness- This is opposite to ductility. Brittle materials show little deformation before fracture and failure occur suddenly without any warning. Normally if the elongation is less than 5% the material is considered to be brittle. E. g. cast iron, glass, ceramics are typical brittle materials. Fatigue Fatigue is a phenomenon associated with variable loading or more precisely to cyclic stressing or straining of a material. Just as we human beings get fatigue when a specific task is repeatedly performed, in a similar manner metallic components subjected to variable loading get fatigue, which leads to their premature failure under specific conditions. Fatigue loading is primarily the type of loading which causes cyclic variations in the applied stress or strain on a component. Thus any variable loading is basically a fatigue loading. Stress Concentration In developing a machine it is impossible to avoid changes in cross-section, holes,notches, shoulders etc. Some examples are shown in figure Any such discontinuity in a member affects the stress distribution in the neighbourhood and the discontinuity acts as a stress raiser. whenever a machine component changes the shape of its cross section, the simple stress distribution does not holds good and the neighbourhood of discontinuity is different this irregularity in the stress distribution caused by abrupt changes of form is called stress concentration. It occurs for all kinds of stresses in the prescence of fillets, notches, holes, keyways, splines, surface roughness or scratches etc. the nominalstress in the right and left sides, of the above mentioned components, will be uniform but in the region where the cross section is changing, a re-distribution of the force whithin the member must take plac. The material near the edges is stressed considerably higher than the average value. The maximum stress occurs at some point on the fillet and is directed parallel to the boundry at that point. Theoratical or form stress concentration factor The theoratical or form stress concentration factor is defined as the ratio of the maximum stress in a member (at a notch or fillet) to the nominal stress at the same section based upon net area. Mathematically, theoratical or form stress concentration factor. Kt = Maximum stress Nominal stress Methods of reducing stress concentration A number of methods are available to reduce stress concentration in machineparts. Some of them are as follows: 1. Provide a fillet radius so that the cross-section may change gradually. 2. Sometimes an elliptical fillet is also used. 3. If a notch is unavoidable it is better to provide a number of small notchesrather than a long one. This reduces the stress concentration to a large extent. 4. If a projection is unavoidable from design considerations it is preferable toprovide a narrow notch than a wide notch. 5. Stress relieving groove are sometimes provided. These are demonstrated in figure
