That's just an excuse - it doesn't say anything about the root cause of
your compulsion to be offensive.

You take offense. I state facts. You are a simpleton on the loony
Libertarian (i.e. anarchist) fringe. You don't like it, think a
bit.
In fact, most people I know except for the really brain-locked actually
rather enjoy my "loonacy".

You think a lot of yourself. Notice the self-serving qualification?
After all, I grew up in Minnesota, and the loon is their state bird.

I took enough college courses in engineering to graduate.
I paid the nominal citizen subsidized rate for the tuition
and bought and kept all my books. I buy texts quite
readily. To make the point, do you have anything to
recommend, or not?
______________________________________________

The previous recommendations are probably the best:

Invest your education in something more productive than
feigning ignorance to trick newsgroup readers into trying
to answer open-ended questions, demanding extensive
mathematical proofs, finally admitting your own expertise
and expressing contempt for those who tried to help.

Don't let yourself deteriorate into a trolling pedantic nit.

Good luck.

That you do not read here in sed much, it is clear. I do not have the
time mess with ignorance, when i challenge ASSumptions it is legit. I
do not want poppycock propagated as truth. This is a technical
newsgroup, i expect those that would wish to contribute to have their
act together. If you want my respect, bring the math when i ask for
it.

Invest your intelligence in something more productive

Good luck.

In other words, you can't translate the simple explanations already
presented to you into whatever formal mathematical form you prefer, and
therefore prefer to denigrate other posters genuinely trying to be
helpful rather than address your own shortcomings.

Don't let the door hit you in the ass on the way out.

Consider a vehicle of axle-to-axle length L,
and left to right wheel separation W (though
I don't believe this matters).

Assume a X-Y co-ordinate plane, the origin
located at the center of the rear axle.

What is the car's forward trajectory,
if the front wheels rotate left at angle U?
What is its reverse trajectory?

What if the car has front wheel drive?

Why does one park into a space by backing
up, rather than forward?

** BONUS CREDIT **

Use your answer above, to solve the parallel
parking problem.

How to Modify Your Car Cheaply to RUN ON WATER

THE PROBLEMS:
Foolish petrol prices, petrol battles, pollution and global climate
change. You know what I'm referring to.

THE BAD One likely way out, that you may have heard of, is water automobiles.
As distinct from water hybrids, water powered automobiles are yet to
be rolled out of the assembly plants. You could get a minimum of 10
strategies of water powered automobiles to try out. Regrettably those
designs are too costly to put together, are very knotty, and
absolutely unpredictable.

THE GOOD Widespread development and experimentation by numerous back yard
engineers has proven one method FEASIBLE. With this method you can run
your traditional automobiles PARTIALLY ON WATER (that's a "Water
Hybrid") with little or no modifications.
"¢ You should be able to increase your gas efficiency by as much as
59% (Toyota 99) or even 70% (Cadillac 99).
"¢ You could drastically cut down discharges and help reduce Global
Warming.
"¢ You can improve efficient burning of fuel and consequently lessen
wear and tear, engine clatter, high temperature in the engine, carbon
deposits, etc.

You see, you have just hit upon a unique piece of information. As
there is a small number of persons on the World Wide Web who will not
sell you products, but rather when you become a member of a group or
club, you will will gain knowledge of how to make these stuffs
yourself at home. A number of them will even provide you a
COMPLIMENTARY HYDROGEN BOOSTER SYSTEM, fully put together set to go
into your vehicle, so you can authenticate its practicability and have
a copy for replication. Again, this is a COMPLIMENTARY GIFT for you,
for becoming a member and a researcher

You could make use of this mock system to switch nearly any vehicle
into an trial, wholly functional WATER HYBRID in one slow day, with
the aid of simple tools at home. Back in I knew nothing about
automobiles, I had no garage and no special tools, yet I installed one
un-aided within a quarter of an hour. This was in an era when all I
had was half a page of instructions. Nowadays you can obtain complete
informational products or ebooks, packed with guidelines and
suggestions. There are also support groups to assist you with any
mechanical, electrical or tuning trouble. These new groups have
labored hard to make it SIMPLE FOR YOU. And it is the influence of the
group that makes your path so much easier and smoother.

IT GETS EVEN BETTER:
You will also be skilled in how to become a home manufacturer of
numerous models of hydrogen generating system. Again, basic skills and
easy tools is all that is need to replicate these systems for your
friends, family or clients. PAY NO ROYALTIES OR LICENSE FEE - you keep
all the cash!

When you get into one of these exceptional clubs or groups, you can
discover answers to your questions:
1. Is this really practical? How come it's so easy?
2. Why didn't anyone tell me about it before?
3. could water technology do for me?
4. Why should I become a member of a group/club?

So"¦you will start to realize why water hybrid (water car / watercar)
secrets have been unknown until today.

The 2 points are not moving around 2 points,
They are both moving around one point.
One is moving faster WRT the other.
2 different size circles centered around the same point.
that is all.

It's the same principle as the rear differential?

Why a differential in the rear axle, and
the Ackerman doohicky in the front?

Mark

The rear axle needs a differential because the rear wheels are
rotating around a point that lies on the extended centerline of the
rear axle (as do the fronts) and therefore are describing circles of
differing radius. As a result the wheels are rotating at different
speeds, and you'd get significant tire scrub if they were locked
together (or you'd simply break stuff.)
