OT? Tales of induhviduals?

[Rich, Under the Affluence]

So, the boss comes into my office this morning, demanding to know the
coefficient of thermal expansion of steel. Well, I don't know the
coefficient of thermal expansion of steel off the top of my head, so
I get him to back off long enough to let me look it up, and it
turns out it's something like 6.8 ~ 8.6 ppm/deg F.

He says, "That's not gooe enough! I have to have the formula!"

I said, "That _is_ the formula. 8.6 parts per million per degree F.
I can't make it any simpler than that, except maybe translate parts
per million into thou and tenths, in which case it's not very many
at all..." And he says, "So, if it's 17.5 inches at 70 degrees, how
many inches is it at 55?"

I made him a little spreadsheet. I was tempted to make a chart,
but all he asked for was a "formula".

It came out to somehting like 17.497" or something. They're obsessing
over a hole diameter in a weldment that has no other tolerance closer
than about 1/16". (about 1.3 mm).

Thanks, just wanted to rant for a mo.

Just tell him it's the same as the tempco of concrete.

....one of the more spectacularly useful coincidences in nature,
because it happens to make modern architecture possible .

Sounds like Dilberts boss

Not really. Dilbert's boss doesn't worry about differential expansion
until it messes up the performance of the sensor that he is trying to
get developed, and then won't go over to a construction that eliminates
the problem, because he's paid a shit-load of development money for the
half-baked construction that is really sensitive to differential
expansion.

Sometimes I feel quite positive about being out of work.

Have some fun, bring some more fuel to the discussion.

"steel" is not mere "iron" there are different *alloys* of the name steel
and there are uncertainties in measuring e.t.c. With luck "management" can
spend *weeks* arguing over "data", while "employees" take advantage ... ehh,
in the best interests of compagny err on the safe side and wait for
approval.

A broad and useless average- modern large scale construction is made
possible by brainpower, know-how, and attention to detail- not a whim of
nature.

Things get a little more complicated when you want to track the
compressive forces of an interference fit of worst case slightly
dissimilar materials over temperature extremes.

Don't forget tp throw in the glass transition temperature of the epoxy
resin being used to fix the sliding fit components of the device - the
I knew about the glass transition temperature of the epoxy resin used
by the mechancis in my sensor was a kink in the calibration curve at
63C. The replacement that I found had a glass transition temperature of
about 140C, which did accommodate a 20C to 85C temeprature range.

So, when I was still working for a electric utility company they hired a
"electrical engineer" from Lithuania (spelling?) to be the superintendent of
our 6 county division. He called me into the office and said a bedroom in
his house had only a pullchain light in center of room. I would like to
change this to a switch on the wall by the door. How do I wire this? I
though he was pulling my leg so to speak. He was serious. His name was
Geroge not Dilbert. After that I had fun. I could blind him with BS and he
never caught on. W W

I've been caught out like that, expecting wiring protocols to be the
same as my home country.

Lithuania has some beautiful women BTW
