Integration in SEC Football - Research Paper Example In southern US colleges, the policy of segregation was deeply ingrained. Universities and colleges refused to admit Black students. Thus, it was natural for their teams to be White with no African-Americans. After the Second World War, the University of northern states desegregated and they admitted numerous African-American players to their respective teams. In spite of this, southern schools remained fully segregated. These colleges went as far as refusing to play desegregated teams from universities from the North even if the games were played in the North2. The Southeastern Conference is a college athletic conference which operates in the southeast of the United States. It has its headquarters in Birmingham, Alabama. It participates in the National Collegiate Athletic Association (NCAA) Division I. Currently, it sponsors team championship in nine men's sports and twelve women's sports. This makes it one of the largest in the world. As a sports institution located in the South, it was plagued with the issue of segregation for many years. It was part of a larger effort to prevent mixing of Blacks and Whites in America. This trend changed when the changes of the Civil Rights Movement hit the institutions of the United States. In doing this, the following objectives would be met: The integration of African-American footballers into the SEC can best be described in the wider context of the SEC and its unique position in American history. This is because SEC football is just a subset of the SEC which went through several changes as a unit rather than in individual sports. Thus, the approach that can best be used would be to examine the SEC as a whole with the emphasis on football. Â  

Rockwell Hardness Testing Lab Report Example | Topics and Well Written Essays - 1000 words

Rockwell Hardness Testing - Lab Report Example Hardness is a measure of the resistance of a metal to permanent (plastic) deformation. The hardness of the metal is measured by forcing an indenter into its surface. The indenter material which is usually a ball, pyramid, or cone, is made of a material much harder than the material being tested. For example, hardened steel, tungsten carbide, or diamond are commonly used materials for indenters. For most standard hardness tests a known load is applied slowly by pressing the indenter at 90 degrees into the metal surface being tested. After the indentation has been made, the indenter is withdrawn from the surface as shown in the figure. An empirical hardness number is then calculated or read off a dial (or digital display), which is based on the cross-sectional area of depth of the impression. The hardness of a metal depends on the ease with which it plastically deforms. Thus a relationship between hardness and strength for a particular metal can be determined empirically. The hardness test is much simpler than the tensile test and can be nondestructive (i.e., the small indentation of the indenter may not be detrimental to the use of an object). For these reasons, the hardness test is used extensively in industry for quality control. The Rockwell Hardness test consists of many different scales for a range of different hardnesses. The B and C scale are the types used in this experiment. The B scale uses the spherical steel penetrator and the C scale uses the diamond cone shaped penetrator. Procedure for Experiment 1. Make certain the crank .It is kept in forward position, nearest to you. 2. Place the sample on the anvil, in position for test. 3. Select 100 and 150 kg combination of weights (being at the rear of the machine) . 4. Slowly turn the wheel spokes clockwise. This raises the anvil and sample toward the penetrator tip. After contact is gently made, continue raising sample until small pointer is about in line with the small black dot and the large pointer is within the colored sector. The minor load has now been applied to the sample. 5. After step 4, the large pointer on the dial is nearly vertical. Now, turn the knurled collar until the SET line on the dial scale is in line with and under the large pointer . 6. Depress the trip lever. This triggers the mechanism that applies the major load. The crank will automatically move away from you. 7. After the crank has come to rest, gently pull the crank back toward you as far as it will go. If this is done abruptly, a false reading
