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

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.

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
