Summary
Now that you have reached this point in the text
- You should know the basic steps involved in the solution of engineering problems: What is
the problem? What is to be determined? Can the analysis be simplified by making appropri-
ate assumptions? What are the physical laws and principles that govern and predict the behav-
ior of the given problem? - You should realize that you must always find your own ways to verify your solutions to a
problem. There are no answer books outside the classroom. - You should realize that it is very important for engineers to know how to communicate well
with others both orally and in written form. You should also be familiar with various ways
of giving an engineering presentation, including a home work presentation, progress report,
executive summary, short memo, and detailed technical report.
