So you have finally done the maths for you (or more likely asked

That change is NOT what happens in a typo; a typo would have produced
"24 (11) feet".

My Trek is the 3400 - nice sensible road bike. Looks very similar to
that, but without the chain guard. Doesn't have all that dodgy brake
stuff, either. A reasonably heavy stop (say from 20mph in 5 seconds)
only needs to dissipate 3kJ at 600W, which is no problem at all to
dissipate in a pair of wheel rims.

You're obviously quite a big chap - not far off twice my weight - so
that, with the extra bulk of the bike, justifies a degree of overkill in
the brakes department IMO. Just adding 10kg of touring clobber makes a
hell of a difference to me. I'm not sure about all the gear gubbins, but
if it floats your boat ...

I've 'regressed' to a mid-90s mountain bike for commuting (low-mid;
Deore LX) with road tyres and cantilever brakes - stops me on a
sixpence, and the best bike I've had in a long time. There was a long
thread on uk.rec.cycling a few days ago going through the
fade/feel/maintenance aspects of brakes. Hydraulic disc brakes the way
to go, apparently (cost/weight notwithstanding).

So long as you don't 'go tandem' to put your underused chauffeur to use,
all should be well. :-)

down in the road. Eiron actually tried the experiment and found an
empirical limit at about 0.35g, and my back-of-an-envelope
calculations show him to be pretty much spot on.

I tried it again this morning, and managed to brake in 18 feet from 30kph,
to mix my units in the approved Jute manner, which works out at 0.65g.
This was sitting further back and lower, with hands on the drops.
Still, 0.65g seems a bit high for a pushbike so I'll have to repeat the
test on my next excursion until I get consistent results.

I expect that Jute never did any braking tests at all on his granny bike;
rather he picked 1g as a figure to be proud of and fudged some numbers
to fit.
When challenged, he picked another, believable number . . .

So you have finally done the maths for you (or more likely asked
someone to do it for you),

Oh, I don't need to ask anyone, Donnie-boy. I wrote the book, and you
know it, which is why you cut out the quote from my book I gave:

For those of you who want to know the science, here is a reliable
authority on the subject:

"The maximum braking force that can be applied to a vehicle through
its wheels -- the mass of air having its own retarding force -- is
limited by the friction between the tire and the road, and is equal to
the weight of the vehicle multiplied by the coefficient of friction.
On a dry pavement, this coefficient could be as high as 1; with a
coefficient of unity, retardation would be 1g or 32.2ft/s^2 and the
stopping distance in feet would be V^2/29.9 where V is the speed in
mph. I must stress though that this is on an ideal surface such as
does not exist outside a test facility..."
(p98, Designing and Building Special Cars, by Andre Jute, Batsford,
London 1985)

For those without the math, the formula transforms as follows to
permit us to calculate average retardation in fractions of one gravity
when we know the entry speed and the stopping distance:

V^2/(29.9*D)

where V is speed in mph and D is stopping distance in feet. Taking my
example of 24ft from 30kph, we need first to convert 30kph to mph,
which is 18.64mph. So (18.64*18.64)/(29.9*24) gives us an average
retardation for the roller brakes, aided by the anti-skid modulation,
of 0.484g. This may be compared, as above, to around 0.4g achievable
with disc brakes and around 3.5g with the sort of rim brakes usually
fitted to racing bikes.

Going upmarket clearly doesn't mean less efficiency -- quite the
contrary: it means extraordinary efficiency. Those of greater
discrimination, who furthermore spend more money, believe they have a
right to a more pleasing product, In this case I have received
excellent value for my money!

and had gravity explained to you,

And no, Donnie-boy, I don't need gravity explained to me either. It is
in my book already: that lower-case g in the results is the symbol for
gravity.

and you
realise that you posted a heap of ****.

No, Donnie-boy, you're the one who posted a heap of ****, who claimed
that brakes are "dodgy" when clearly they are not (when with only a
little practice they give a 0.484g retardation!), you're the one who
claimed, without any proof or knowledge, merely from your unshakeable
stupidity and lack of curiosity (which ill becomes an "engineer") that
something is impossible -- and now your loyal sidekick in these
abuses, Eiron, has written that he performed an experiment which
proves that what you say isn't impossible. (I have no opinion about
whether an 0.65g retardation as claimed by Eiron is possible on a
bike; unlike you I don't spout off until I investigate.)

Are you going to withdraw your
intemperate comments to Eiron and me now?

I didn't make any intemperate remarks. You're the one running around
accusing everyone who doesn't instantly bow down to your superior lack
of knowledge as a liar:

That change is NOT what happens in a typo; a typo would have produced
"24 (11) feet".

You don't know **** about typography either, do you Donnie-boy?.Buy
one of my books on typography, listed at my netsite, and you will be
better informed in future. If you pay attention, of course, and don't
bluster about how much more you know just because you're Don Pearce.

Ah, that eleven feet is a typo. It should be 24 feet, impressive
enough, I think.

You're obviously quite a big chap - not far off twice my weight

I congratulate you on weighing 46.5Kg! No, I was talking about the
bike loaded for light touring, at least an overnight stay.

- so
that, with the extra bulk of the bike, justifies a degree of overkill in
the brakes department IMO. Just adding 10kg of touring clobber makes a
hell of a difference to me. I'm not sure about all the gear gubbins, but
if it floats your boat ...

Well, I bought it because I'm a techno-freak. But there is something
about the Cyber Nexus gubbins I didn't consider before. I thought I
used my other bike, which has manual Nexus hub gears (exactly the same
thing but without the electronics) reasonably well. But once I started
riding the automatic gears it was pretty obvously they were changing
so much more optimally that my rides were not only concluded a little
faster but that my heart rate was controlled much more optimally. I
think it is just human nature to hang on the gear too long...

I've 'regressed' to a mid-90s mountain bike for commuting (low-mid;
Deore LX) with road tyres and cantilever brakes - stops me on a
sixpence, and the best bike I've had in a long time. There was a long
thread on uk.rec.cycling a few days ago going through the
fade/feel/maintenance aspects of brakes. Hydraulic disc brakes the way
to go, apparently (cost/weight notwithstanding).

I have a Nexus equipped bike with a front disc brake as well. Like the
roller brakes, it is overkill, even in the hilly country in which I
live, though it saved my ass in a situation where I was speeding down
a hill and a car with a trailer pulled across the road in front of me
and stopped there -- I stopped with my boot on the driver's face
through his door window, so clearly with less capable brakes it would
have been a nastier crash (for me -- it was no holiday for the dumb
motorist, who was spitting out teeth); the nicest thing about discs or
rollers in everyday use is that they don't start stlipping in the wet,
like rim brakes.

So long as you don't 'go tandem' to put your underused chauffeur to use,
all should be well. :-)

Now that's an idea!

Rob

D'you know what I regret, Rob? A few years ago when I ordered a Royal
Dutch Gazelle delivered from the Continent, I gave my old bike to the
LBS just to retain his goodwill; I didn't want him to change his habit
of doing whatever I want done on my bike instantly, while I wait. That
bike was an 80s-90s Peugeot manganese alloy concoction in a reasonable
mountainbike geometry, beautifully fillet-brazed. I should have kept
it, thrown off the worn-out fifteen year-old Sachs-Huret mechanics,
had the frame sandblasted and painted, and built it up again with best-
quality parts. You just can't buy a frame of that quality now without
going to some custom maker and paying out a lot of money, and then
you're never certain of what you're getting.

Ride tall, brother!

What have 11 and exclamation marks to do with this, idiot? Your error
was between 11 and 24.

And no, Usenet is not typeset. You write your stuff, and it goes where
it goes. When you set type you can insert white metal shims to adjust
the type - that is typesetting.

You have already shown that you don't understand the content of your
books by your mistaken reference to friction as being the controlling
factor in slowing a bike. I assume the same holds true for every

you spout off, Donnie-boy?

What have 11 and exclamation marks to do with this, idiot? Your error
was between 11 and 24.

See, Pearcey, in a moment of literary weakness, because I was writing
to you, a known sluggard and smug and aggressive with it, I put two
exclamations in parenthesis behind the number 24 to draw attention to
the fact that I knew it was exceptionally good. Now -- only a brief
digression which the short attention spans like you may skip --
normally I would come down with a sarcastic remark on anyone who uses
two exclamation points when one will do, but in your case I thought
I'd better permit myself the superfluity. Okay, back to the
exclamation points and the number 11. If you type two exclamation
points on your keyboard, you do it by holding down the shift key and
typing the number 1, yes? Try it now so you don't lose the step and
start making a fool of yourself again with empty abuse. Right, now put
a piece of text with two exclamations in it in your word processor,
select the text, and then go find the availble fonts you can change
that text into. Keep trying them one by one. Eventually you will find
several that put what to an typographical ignoramus like you might
appear to be garbage symbols (only the empty square is, and then only
sometimes) in the place of the exclamations, or arabic numeral 1. If
you can't work it out from there, just ask and I'll patronize you some
more.

And no, Usenet is not typeset. You write your stuff, and it goes where
it goes. When you set type you can insert white metal shims to adjust
the type - that is typesetting.

You must have learned your little minimum bit of exceedingly
misleading "knowledge" when you were a very small boy, and now be very
old. Or perhaps your parents were too poor to afford an up-to-date
encyclopedia. Modern typesetting has been done on computer keyboards,
and by computer instruction, where fonts are interchangeble for the
same text, for nearly half a century.

This is an excellent example of your blustering arrogance, Pearce. You
are talking to someone who knows the subject, who has an international
reputation in it and who has earned a rich living from it, who has
written several standard texts on the subject, who knows just about
everyone who knows more about it than he does (and they too have
written texts in a seies of books of which I was general editor) --
but you claim to know more.

You have already shown that you don't understand the content of your
books by your mistaken reference to friction as being the controlling
factor in slowing a bike.

You keep making the same arrogant mistakes, Don. First, you clearly
don't understand the difference between "controlling factor" and
"limiting factor". Where were you educated, if you were? You should
ask for your tuition back. I quoted a piece from my book that speaks
of the upper limit of retardation of any wheeled vehicle, you
immediately, quite contrary to the quoted text, presume I'm speaking
of "controlling factor", which further leads us to wonder if you have
a comprehension difficulty with the English language. Secondly, you
presume that the small piece I quoted from my book to put you down
like an impertinent puppy, is the entire entry on brakes. It isn't,
there are pages more, including a big section on weight transfer,
which may be what you're trying to accuse me of not knowing about
(that's a good example of how one puts the boot in without opening
oneself to accusions of crude brutality, hmm?).

I assume the same holds true for every
subject you care to cut and paste into something thick and tedious.

You don't assume, Donnie-boy, you presume upon my patience. My book on
automobiles was approved of and given to junior engineers as their
bible by a major motor manufacturer. Please explain to me why I should
believe some blustering internet-"engineer" like you knows any better
than professional engineers?

The same applies to my books on reprographics (of which typography is
a part); they are the officially sanctioned texts of people who know
their business. But Don Pearce, who postures on the net as an
"engineer", knows better! Holy ****, who do you expect to believe you,
Pearcey?

Get real, man. You don't know ****, and you never will until you
change your attitude.

I'd like to know what you believe you are today - weren't you a
scriptwriter for Paul Hogan or somebody just the other day?

Come on Pearcey, it isn't my fault that you're a one-tune dullard. If
you weren't so frightened of the natural curiosity of your monkey
genes, so much more set on dignity above knowledge, you too could be
clever and widely knowledgeable. As for Hogan, you're lying again, I
didn't say I was a scriptwriter for him, I said I threw out a few one-
liners for him when we used to eat in the same caff on King's Cross,
an entirely different matter, as you would know if you knew anything
at all about show business. But I'll let you make a fool of yourself
again by claiming that's an entirely different career before I shoot
you down.

Exactly my point, Pearce, that you're malicious scum entirely

In the thread "Smooth Mover: bicycle with electronic gearchange and
adaptive suspension" Don Pearce told us:

"that comes out at 1.05g" complete with his formula for "Anyone who
wants to do the sum the easy way.... (30 kph)^2 / (2 * 11 ft) in g".

So let's do the sum and see what we get: (30*30)/(2*11) = 40.9. Nope,
Pearcey, that isn't 1.05. Let's try using compatible units, hmm? 30kph
is 18.64mph, so now let's try (18.64*18.64)/(11*2) = 15.8. Oh dear,
not 1.05 either. Looks like you got a simple formula wrong, Pearcey.
So now, let a reliable authority straighten you out:

"The maximum braking force that can be applied to a vehicle through
its wheels -- the mass of air having its own retarding force -- is
limited by the friction between the tire and the road, and is equal to
the weight of the vehicle multiplied by the coefficient of friction.
On a dry pavement, this coefficient could be as high as 1; with a
coefficient of unity, retardation would be 1g or 32.2ft/s^2 and the
stopping distance in feet would be V^2/29.9 where V is the speed in
mph. I must stress though that this is on an ideal surface such as
does not exist outside a test facility..."
(Andre Jute: Designing and Building Special Cars, Batsford,
London 1985, p98)

This correct formula, transformed just slightly, permits us to
calculate average retardation in fractions of one gravity when we know
the entry speed and the stopping distance (which is what poor Pearcey
is trying to do):

V^2/(29.9*D)

where V is speed in mph and D is stopping distance in feet. Taking
Pearcey's of 24ft from 30kph, we need first to convert 30kph to mph
(which Pearce overlooked). So (18.64*18.64)/(29.9*11) gives us an
average retardation for Pearce's numbers of 1.05g

At last, the right answer, after applying expert knowledge to
Pearcey's errors. So how does Pearce get the formula wrong, forget to
regularize the measurements, and still get the right answer? Simple.
He tells us himself that he "just pop this into Google. I rarely use
an other calculator these days."

In short, Pearce doesn't know how to do a simple engineering
calculation, he gets formula wrong, he doesn't know to use compatible
measures, he doesn't understand what he is working with, he depends on
Google's idiot service to somehow give him the right answer. Then he
gets abusive when it is pointed out to him that he doesn't fully
(that's putting it very politely indeed!) understand the principles,
that he confuses the theoretical limit of deceleration of a wheeled
vehicle with the controlling factor under a particular set of
circumstance.

Arthur C Clarke said that any advanced technology will appear to a
savage as magic. Don Pearce's magic for technology he doesn't
understand is the Google calculator. He has faith in it. He gets very
angry when its use is questioned.

All this, especially Pearce's vicious attempts to prove everyone else
wrong, and his anger when his errors are pointed out, do make one
wonder how Pearce can ponce around calling himself an engineer.

Yikes, John.

Just change 11 feet to 3.353 meters.
30kph = 30,000 mph/60/60 = 8.33 mps.

Comes to a bit over 1.05G whomever calculates it.

Now, let's use Mr. Jute's Formula:

Oops... same result.

Now the bottom line is that an individual by his own admission at 1/8
ton (for gentleness, we will call it a "short" ton of 2000 lbs. avdp.
= 250 pounds/2.2 = 113.6 kg.) goes from 8.3 mps to 0 mps in 3.353
meters... whatever smoke and mirrors are applied and surrounding it.
And we will allow the bicycle as being part of that short ton. A long
ton (2200 pounds, 1000kg) only makes the impact a bit more painful.

Now just use your basic intuitive knowledge, no math required. Grade-
school science. G = 32/s/s. One second, fallen 16 feet, speed = 32fps.
2 seconds, fallen 48 feet, speed = 64fps. And so forth.

That is very nearly the functioning equivalent of running into a brick
wall. If you want an equivalent for it, imagine you have fallen ~ 14
feet onto whatever... that is about what you would be doing at the 14-
foot mark. Oh, sorry, you have fallen about 4.26 meters.

So, gravity gives you ~8.3mps in 4.26 meters (9.8M in 1S). Jute's
fantasy machine does it in less (3.36M). Therefore in more than 1G.
How much more is not the point. But 0.05g is certainly close enough.

As Jute's amanuensis, you need to pick your battles more aptly.

Peter, your problem is that you have not yet correctly identified the
"battle". This bicycle stopping distance business has nothing to do
with it, I haven't even been following the math and computations which
are of minimal interest to me in this instance, what I was playing off
of and generalizing on was Andre's mention of Don's use of Google, which
I suddenly realized explained a lot of things.

If Don choses to take exception to my general comments on his modis
operandi with respect to Google, then I may have to get more specific,
in the mean time it will be interesting to see if you can identify the
specific "battle" that prompted my comment, hint it is totally unrelated
to Andre or any of his threads.

Indeed you did, Pearcey, and I so reported, not just once but several
times. But you snipped the part of my letter where I did so, perhaps
to justify calling a liar. But you're the liar, because I didn't snip
your words, as you snipped mine, I reported them in full, and sneered
at them in full, perhaps too fulsomely for you to bear. I give my
entire post again below, so that everyone can see what foul lying ****

But that's the point, Pearcey, that doing it the long way teaches and
reinforces understanding of the interrelationship of the factors,
something you are direly in need of, as has been amply demonstrated in
the Smover thread, where you repeatedly showed us you are ignorant of
quite simple matters regarding acceleration and deceleration.

You really are a pointless sack of ****.

Oh, not pointless, surely. I serve to correct the lucanae in your
knowledge and to whisper in your ear that you don't know everything.

And here is my entire previous post again, so that everyone can see
that you are, in your own words, a lying sack of ****:

Comes to a bit over 1.05G whomever calculates it.

Now, let's use Mr. Jute's Formula:

Oops... same result.

Now the bottom line is that an individual by his own admission at 1/8
ton (for gentleness, we will call it a "short" ton of 2000 lbs. avdp.
= 250 pounds/2.2 = 113.6 kg.) goes from 8.3 mps to 0 mps in 3.353
meters... whatever smoke and mirrors are applied and surrounding it.
And we will allow the bicycle as being part of that short ton. A long
ton (2200 pounds, 1000kg) only makes the impact a bit more painful.

Now just use your basic intuitive knowledge, no math required. Grade-
school science. G = 32/s/s. One second, fallen 16 feet, speed = 32fps.
2 seconds, fallen 48 feet, speed = 64fps. And so forth.

That is very nearly the functioning equivalent of running into a brick
wall. If you want an equivalent for it, imagine you have fallen ~ 14
feet onto whatever... that is about what you would be doing at the 14-
foot mark. Oh, sorry, you have fallen about 4.26 meters.

So, gravity gives you ~8.3mps in 4.26 meters (9.8M in 1S). Jute's
fantasy machine does it in less (3.36M). Therefore in more than 1G.
How much more is not the point. But 0.05g is certainly close enough.

As Jute's amanuensis, you need to pick your battles more aptly.

Peter, your problem is that you have not yet correctly identified the
"battle". This bicycle stopping distance business has nothing to do
with it, I haven't even been following the math and computations which
are of minimal interest to me in this instance, what I was playing off
of and generalizing on was Andre's mention of Don's use of Google, which
I suddenly realized explained a lot of things.

If Don choses to take exception to my general comments on his modis
operandi with respect to Google, then I may have to get more specific,
in the mean time it will be interesting to see if you can identify the
specific "battle" that prompted my comment, hint it is totally unrelated
to Andre or any of his threads.

John:

Mpffffff.... and with respect even if choked out of me..... Mr. Jute
is incapable of honesty or straightforward behavior. His response to
criticism, his errors and his bald lies is universally bullying and
meretricious.

So, whatever the failings and failures of his detractors and
supporters, they are lesser than those of the target and/or master.

You need to understand that by not supporting one individual, I am
quite capable of not supporting his/her enemies or detractors as well.
I have spent time in the Middle East, but the common "enemy of my
enemies is my friend" philosophy of that region is not mine. And vice-
versa, of course. I am also even capable of being supportive of
individuals on both sides of an otherwise poisonous division.

In the thread "Smooth Mover: bicycle with electronic gearchange and
adaptive suspension" Don Pearce told us:

"that comes out at 1.05g" complete with his formula for "Anyone who
wants to do the sum the easy way.... (30 kph)^2 / (2 * 11 ft) in g".

Jute, you are a foul, lying weasel. Despite your lying editing-out of
the relevant words (from within a line even!) I told you to put that
formula into Google. Although it suits you to pretend you don't know,
Google handles all the different units quite happily, and provides
exactly the right answer, which is 1.05g. If you want to do it
manually, you must convert kph to metres per second and feet into
metres then divide the result by 9.81. Want to do all that the long
way when Google will handle the unit conversions for you?

Don, Andre's observations on your use of Google formulas may finally
explain the mystery of your apparent lack of understanding of much of
the material you post to usenet. The simple Parroting of information
found on Google would go a long way towards a possible explanation.

Yikes, John.

Oley Polony, this poor dumb cluck Worthless Wiecky is another Parrot.
He has taken poor old Pearcey's 11ft over without realizing that a
retardation in excess of 1G is impossible.

In fact, all these little scumballs, like Pearce, trying by
misrepresenting a typo to make out I made a gross error, would be
better employed by the more reasonable argument that even 0.484g (24ft
from 30kph or 18.64mph) is exceptional, in fact so good that even the
hostile Eiron at first agreed with Pearce's statement, in his
ignorance, that anything near 0.5g is impossible; since then Eiron has
surprised himself by making an even better stop than my best one.

It struck me too a blinding blow; I had been wondering for years if
Don was just very poorly educated, or if some leftbrain-rightbrain
slippage accounted for the stupidities he comes out with every so
often, then defends beyond all reason, indeed with a great deal of
anger and abuse. Then he told me to use Google's Black Box for Known
Idiots and all became clear in an instant.

If Don choses to take exception

Pearce is too thick to grasp a warning. He's a jerk-up: he will come
out swinging.

to my general comments on his modis
operandi with respect to Google, then I may have to get more specific,
in the mean time it will be interesting to see if you can identify the

I doubt that Blustering Don Pearce is worth a battle at all, purely on
the grounds that nothing will be learned in return for the effort, no
truth confirmed. He isn't even as intelligent as Pasternack; in fact,
after recent experiences (Pinkerton, Poopie, Krueger, Pearce) I'm
starting to view even that moral cripple Pasternack with nostalgia:
after all, he merely lied about electronics and was quickly caught
out; he wasn't actively ignorant.

I love your irony, Jute. Calling me a "stoolie", when it was YOU who posted

Still, I'm glad you caught it; I always worry when I include a
