RE: Hand calcs vs. computer calcs

[Subject Prev][Subject Next][Thread Prev][Thread Next]
That's right, Bill.  As well, there are many examples of "registered"
persons signing calculations who clearly demonstrate that they don't have a
clue on load paths, free-body diagrams, equilibrium,
bending/shear/deflection/secondary stresses, etc. and "orders of magnitude",
even if they do check their output for "big errors", and I think all of this
automation may be adding to that problem.

I guess his point wasn't that "you should do this," since no one would argue
with you.

But rather, he is pointing out that, despite what we might agree "should" be
done, it ISN'T being done. Witness the fact that the H.S. math teachers
apparently have no qualms about not teaching the fundamentals of graphing
algebraic functions by hand.

I don't know for sure, but I have a sneaking suspicion that the teachers
THEMSELVES probably don't know how to do this!
