an acceptance test for the specification of materials. The teaching and learning of tensile testing was based on laboratory experiments used in the Mechanical Engineering Laboratory (CM180) at the City University. The experiment looked at how the microstructure of a material can affect its properties. It also introduced tensile testing and stress-strain curves. It is done by using of a tensile testing machine. Three basic types of materials were used in the experiment. They were a) mild steel

English I CPE/period 9 15 January 2013 Standardized testing should not be required to graduate high school Sitting in a classroom for forty-five minutes feels long and stressful. During the standardized tests students have to sit in a classroom for hours at a time‚ knowing that their future dreams of being a doctor‚ teacher‚ or lawyer could come to an end if they mess up one exam. Standardized tests should not be required for students to graduate high school. They cause students

Growing up with a parent who was not only just an educator‚ but one who was aware of the biases that these test included made me less affected by them. One challenge that I face when I do think of this subject from an Afro-centric perspective is that I cannot be only concerned with that fact that I was not affected‚ but I have to be concerned

Does animal testing work? Yes- 1. Animal testing has helped to develop vaccines against diseases like rabies‚ polio‚ measles‚ mumps‚ rubella and TB. 2. Antibiotics‚ HIV drugs‚ insulin and cancer treatments rely on animal tests. Other testing methods aren’t advanced enough. 3. Scientists claim there are no differences in lab animals and humans that cannot be factored into tests. 4. Operations on animals helped to develop organ transplant and open-heart surgery techniques. No- 1.

tests for years. Testing in the schools has swelled and mutated and threatens to swallow our school systems whole. Standardized tests in the public school system have become biased and they are costly to school systems. In this presentation I will go over some of the cons of standardized testing. One is that the tests given to our students today are biased to our children that certain questions can only be answered by particular groups of students. The second con of standardized testing is that these

Drug Testing before receiving financial aid from the government to support your family. Lately the media has been following the legislatures and their bills involving mandatory drug tests before receiving government assistance. “According to the Survey of Income and Program Participation conducted by the U.S. Census‚ well over 100 million Americans are enrolled in at least one welfare program run by the federal government. Many are enrolled in more than one. That is about a third of the entire

Tensile Testing Of Metallic Materials 概要： Tensile testing of metallic materials is specified according to European EN 10002 standard. In this article the terms‚ definitions and designation for tensile test made at ambient temperature is described. The test involves straining a test piece in tension‚ generally to fracture‚ for the purpose of determining mechanical properties. Tensile testing of metallic materials is specified according to European EN 10002 standard. This standards consists of five

This particular experiment could be very useful to scientists as a similar procedure could help identify genetic diseases and could also aid in finding cures for those genetic diseases. Based on assumption our hypothesis was formed and it was believed that the banana would yield the most DNA after undergoing our test. We came to this assumption from the idea that the banana was denser than the other samples‚ and would
