Nothing is perfectly rigid, a strain gauge on the rod will easily pick up
the twist in a rod accurately enough to determine the torque and angle it is
twisted.
On the older style mechanical systems they probably have a special small
section that is a more flexible than the actual rod, that incorporates the
valve design etc.

Mmm, OK.
Presumably you want it to not be *too* flexible though, lest the power
steering mechanism stops working. It would be nice to still be able to
steer. ;-)
Tell me, does this mean that there's no such thing as an inelastic
collission outside of textbooks?

Last Wednesday morning we had 12 inches. When I looked outside, my Miata wasn't
much more than a bump in the driveway. Since I live on a side road that usually
doesn't get plowed till late, I turned around and went back to bed. Didn't make
it out until about 3PM. All the roads are now clear, but we still have 8 to 10
inches of snow still on the ground.

12 inches. Now that sounds like an actual snowfall.
OOC, where is this?

Well yes, I assume we're talking about "flexible" enough to allow a tiny jet
of hydraulic fluid to open under really vigorous steering, not a bit of
rubber that's going to twist through 180 degrees :-)

YOu mean no such thing as an *elastic* collision? No, not at a macroscopic
level. Any collision is going to lose some energy to sound, heat, plastic
deformation etc, some things get pretty close though.

Indianapolis. This was the worst snow in about 5 years. Normally we'll get a 6
to 8 inch fall sometime during the winter. So a little worse than usual but not
terrible.

Yes, very interesting. The world can sometimes be a very small place. AFAIK
the company I work for does not have any offices or subsidiaries in the UK.
Actually our corporate HQ is in NY, IT and a distribution center is here in
Indiana.

There are all kinds of shared-bus network protocols designed for inside of

if all the devices in the door had their own wires.

Well, I mean, there's only, what, 50 states in the USA? Given that my
company has 3 sites over there, *somebody* is bound to be in the same
state as one of them! ;-)

No, I mean... it's not "really" possible for two solid objects to hit
each other without deforming at all.

I dunno. My wife grew up in China, like a billion others, and she's
constantly running into old school buddies and such. I'm saying every couple
of months we find out someone she went to high school with on the other side
of the world either works down the hall, lives down the street, .....
It's kind of freaky.
One day shortly after we moved in, she looks out the window during breakfast
at the neighbor's yard and says "I think his name is Jeff. He was at a
conference I went to in New York." And it was.
Very long-tail.

Hitting without deforming is called an elastic collision, if that's the
confusion.
At the macroscopic level, that doesn't happen. At the quantum level, things
don't "hit" at all. :-)

As someone once said,
"Gravity is far weaker than electromagnetism. To demonstrate this,
consider a person jumping off the top of a tall building. It takes 60
seconds for gravity to accelerate your body as you fall, but only 0.08
seconds for electromagnetism to bring it to a halt at the bottom."
Mmm, messy. :-D

Well, one of the things that always amused me was seeing cities shut down
down south because of a snow amount like what you got. The thing is, all-
weather tires on cars isn't common in the southern US AFAIK, and the
south tends not to have snow removal equipment. Couple that with people
who have never actually driven on anything worse than a wet, oily road
and put them on a skating rink....it can get more dangerous than driving
with experienced winter-weather drivers in Utah on black ice.
How much snow removal equipment is there in Milton Keynes?

Well, I grew up in Minnesota and spent Christmases in Chicago when I was
a kid; I learned to drive on packed snow and ice, so there isn't much
that bothers me to drive on, even black ice (though obviously not my
first choice of road surface because that stuff is incredibly dangerous).
We've got maybe 3" of snow on the ground right now here in Salt Lake
City. Up in the mountains, though, there will be more than a hundred
inches of snow by now. For example, Alta, a place my wife and I like to
hike during the sunner, has 101" of snow right now.
But Alta is also at an altitude of 9,664 feet ASL.

Yeah, that is kinda weird. I've had similar experiences - a few years
ago, I ran into a friend of mine of many years at the airport in
Columbus, OH. He lives in Texas and I live in Utah. I had left my
sunglasses in the rental car and went back to get them, and when I got
back into the terminal, he was literally standing behind me on the
escalator into the terminal, and he recognised me from behind and said
"Jim, what brings you to Columbus?"
Then I ran into another long-time acquaintance getting on board the
connecting flight out of Cincinatti. That was funny because we instantly
recognised each other, but couldn't remember each others' names.

Well, since yesterday every single main road in the city has been
gritted, and even some of the minor estate roads. It's still snowing
right now, and yet there's no snow laying on any of the road surfaces
yet except *right* outside my front door. That can't be too bad, eh?
(Milton Keynes is arranged in a grid of roads, so saying that the main
roads are gritted means that you can basically get between any two
points in the city easily.)
Many of the roads outside the city aren't so clear, but so far today I
haven't seen anything that I'd remotely consider "dangerous". Now, if
this lot melts and then freezes again over night, *then* we'll have a
problem...

Because the objects hit, deform, spring apart, and then return to their
original shapes. Like stretching elastic, you see, compared to stretching
noodles or something.

I would have through elastic would mean the objects deformed, and
inelastic would mean they didn't deform, but hey...

They both deform. The question is whether they spring back. If they didn't
deform, they wouldn't bounce. Think about it, visualizing it at a tiny scale.

That's interesting, because Salt Lake City is arranged on a grid as well.

Yes. I was saying, in a theoretical context, people often assume that
objects collide with no deformation, but presumably in the real world
this never actually happens...

As of today the current snowfall total for the season here is 95.4 inches.
More is supposed to be on the way tomorrow.

Impressive, but a lot of that looks like drifts rather than accumulation
of precipitation. ;-)
Of course, now I can't find the photos I took from a couple years ago
here in Utah. ;-)

Cool, but how about having the centre point as the minimum temperature in
the dataset rather than zero - it looks a bit confusing with the negatives
going into June and July - still really cool though - did you use POV for
that?

Southern Finland (~80km north from Helsinki central), somewhere around
15-20cm and been on the ground for a week or two.

I have never heard the assumption that the objects don't deform. Assuming
small elastic deformations during the collision is popular, or even small
inelastic deformations, but never *no* deformation...
Even at school I remember doing the coefficient of restitution in physics
classes, that allows you to calculate what happens during inelastic
collisions:

OMG! LOL!
I'm loving the way the snow is piled higher than an adult human... ;-)

I'm pretty sure the people knew a hurricane was coming towards their
city, and that they knew their city was built below sea level. Not my
fault they didn't get out of the way.

That's because the snow fell somewhere up North, this time it fell
somewhere important ;-).

You're a single mom with three kids, a dog, a sick grandmother, no car
and 17$. Where do you go? How?
Some people were idiots for trying to ride the storm (see also
Galveston, TX, last summer), but many people stayed because they had no
other alternative.

Not to be cruel, but that's kind of why you're living there. It's cheap
enough for you to afford because every once in a while, you're totally
hosed. If you could afford to flee on a day's notice, you wouldn't be living
where you might have to flee on a day's notice.

Some verifiable statistics on how many people fell into this category of
need would be useful to the debate.
