Final Comments
As with any open-ended problem; i.e., a problem with no single correct answer, the problem
statement above is deliberately vague. You may need to fill in some missing data by doing a
literature search, Internets search, or making assumptions. The possibility exists that as you
work on this problem, your questions will require revisions and/or clarifications of the problem
statement. You should be aware that these revisions/clarifications may be forthcoming.
Moreover, in some areas (e.g. sizing/costing) you are given more data and information than
what is needed. You must exercise engineering judgment and decide what data to use. Also you
should also seek additional data from the literature or Internet to verify some of the data, e.g.
the prices of products and raw materials
