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 
cars. You wouldn't be able to open your door for all the cables in the hings 
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.

Certainly not for you. :-)

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

Yes, that would be a problem.  I wonder if it had done that last night?

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...

Taken on March 8, 2008, at 3pm.  Notice how dark it was!  It was the 6th 
(and last!) snow storm of the winter, each dumping more than 30cm of snow.

The following pictures are as we dug ourselves out, the next day.

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

I made a little comic in honor of groundhog day, which is today

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:

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.
