you can manage a pretty good simulation with a heavy cart. we use
some wagons for carrying 14-3500 lb of steel beams around and once
they get going it's hard to stop them again.

assuming you keep your head about you that's true. i'm guessing a bit
of creative panicking could manage to make the situation worse. and
some people just have the damndest luck too. a friend of mine stopped
in toronto at a sub shop looking out the window across the street
watching people go by when a young man hopped over a concrete wall.
seems there was a 30' drop on the other side of the wall but he was
chatting with some other people and acted without thinking. poor guy
was killed by the drop.

I'd have to re read that part of the story, but I thought she was just
amused at the results.

I don't think it's going to matter. It's not going to be that hard a
fall and you'll have time to react to it.

Yup if you manipulate W = E*I (power equals voltage times current) by
inserting Ohm's Law equivalences [E = I*R] you get W = ( I^2).

The voltage drop along the line, times the current in the line
represents the amount of work done in heating the conductor, the
copper losses.

W = (I * [I*R])

Few, certainly - among people who know what's what.

But this is a new chum - someone who has no idea how to handle himself
in low-G conditions.

I did something similar once - hopped a fence and discovered that
there was a six-foot or so drop on the ohter side. OTHO, there was a
drunk with a gun on the side i came from...

Manymany years ago, returning from a convention in Louisville or
Nashville, Susan and i saw a deer that had somehow gotten onto I-24 on
the Monteagle Grade.[1]

Poor thing must have come from the uphill (inner) side; it dodged and
ducked in three lanes of heavyish traffic, finally made it to theother
side, and leaped the safety barrier.

Over about a 500 foot drop.

[1] If you've ever heard the song "Legend of the Bandit" from "Smokey
and the Bandit", it doesn't exaggerate the way the the Monteagle Grade
(I-24 between Chattanooga and Nashville_) is regarded by those who
know it,.

Considering the 'World-as-myth' books of a later period, we can speculate
that Lazarus or Hilda or one of the other Circle of Ouroboros put it there,
maybe even John Sterling himself. Wink

Sorry, meant to say "the Galactic Overlord himself".

the gravity part won't be that hard - but the forward velocity you had
before you floated is gonna still be there. i knew a guy who broke
both wrists trying to catch himself in a fall that began from less
than his full height,

I know it very well, both as it is today and as it was between 1958 and 1962
when I attended college at The University of the South in Sewanee about 6
miles west of Monteagle on hwy 41. In those days, before it was I-24, what is
now only the 'down' side before they built the new 'up' side on the eastern
side of the mountain, was both up and down. I had some scary rides going to
and from college on that road. Now and then a number of 18-wheelers would
lose their brakes and 'usually' were able to hit the 'runaway' exit about
half-way down the mountain. A lot of times, they missed and went over the
side. (That still happens today). Seeing one of those things coming at you in
the rear mirror can really make you nervous. These days you can move over out
of its way, but in the old days, there was no where to go without facing
oncoming traffic.

Fortunately, the frequently occurring fogs didn't drop too far down the
mountain. Fog on top of the mountain was often fearsome. One night during
exam week, we made the 6 mile drive from Sewanee to Monteagle in an hour and
a half, by sticking our heads out the window and following what we could see
of the white stripe down the middle of the road.

There are two of those now, and they're on the inside, as i recall.

A friend of a firend - an insurance adjustor - was talking to a truck
driver who'd taken the runaway ramp with a cargo of frozen beef (which
was gonna be thoroughly spoilt before they got him out of there,
likely).

The trucker was sitting in his cab with the door open and his feet
dangline when another 18-wheeler lost its air and took the ramp -
knocking the truck already there over the side.

The driver barely managed to jump in time; he got abnged-up enough
that they took him to the emergency room, just in case.

The insurance company got a letter from him from Indiana, telling them
where to send the check - he'd had a revelation: "Don't drive trucks
no more.

I am fairly sure that the original one on the outside is still there, but I
do believe that you may be right and that a second one has been added on
the inside. I live about a hundred miles south of there, but haven't been
over the road in a number of years.

If it's anything at all like the Grapevine above Bakersfield, I want
