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.

Mmm, interesting. My company's HQ is in that state...

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! ;-)
