I have learned a lot by just doing this homework assignment. I have learned about structural and mechanical engineering, and how engineers use these fields of science to try and perfect human life. I also learned about the various tools that these engineers use when creating/inventing something. They use the basic laws of physics, and then they continue on perfecting it until it has become the product. Then, as in some situations, they either test it, or leave it as is depending on the time situation. If testing, they test, improve, then retest, until all the faults are gone. Then that becomes the ultimate product. I would like to actually see this in real life, not just read and look at samples from engineering schools.
