Dear All,

BEWARE!! PLEASE DO NOT USE ANY SPREAD-SHEET BEFORE VALIDATING THE RESULTS.

I've seen hundreds of spread-sheets in my career so far, mostly developed by industry professionals, I too have my own spread-sheets which I use time to time. The biggest probem with these spread-sheets are, they seem to work perfectlly fine as long as user knows how it works and how to interpret its results. But for a new user, it is a very risky business.

Please use this spread-sheets with extreme caution, know what are the limitations of the calculations, know how to interpret the results. Make sure that there are no macros.

I would recommend that one should always try to solve a sample calculation by hand and verify the results of the spread-sheet to make sure it works.

Wrong results coming out from these spread-sheets might lead to a faulty design which can to a lead to a catastrophe injuring or even killing people.

ARAZA.
