I gave up filling, but is there any chance the water will damage the
AD-5?
Should I try and evacuate the shock?
If so, should I do so with the valve down to drain the shock?

i'd strip, dry, re-lube and reassemble. water is essentially
incompressible and can over-pressurize things. it can also freeze and
burst things as we enter the cold season.
Hopefully "jim" is referring to the shock and not himself, but with the
indefinite reference, that determination is not possible.

The bulk modulus of water is 2.15×10^9 Pa.

Stop using indefinite references. Good thing you are not preparing
deliverables for clients with this degree of sloppiness.

Since "jim" in the past has shown an unwillingness to look up and post
values, air is 1.42×10^5(adiabatic bulk modulus) or 1.01×10^5 Pa
(constant temperature bulk modulus). This is roughly four orders of
magnitude lower than water.
Of course, without knowing the quantity of water, it is not possible to
determine to what extend the stiffness of the fluid "spring" in the
shock will be affected.
only 4 orders. that's not significant then! move along folks - nothing
to see here.

civil engineering 101 - dress presumption as fact since you can't test.
The significance depends on the relative proportions of air and water.

Lots of things can be and are tested. But feel free to live out in the

er, no, the significance depends on 4 orders of magnitude!

more civil engineering wisdom?
Do you recommend against filling shocks with ambient air, since it
contains some water vapor, then? Or do you admit that at some proportion
the presence of water becomes insignificant, despite its much greater
bulk modulus?

If you want to avoid structures that have not been destructively tested,
there is little choice but to live out in the open. I suppose you could
buy a series of small prefabricated sheds and test them to destruction
with wind, snow and earthquake loads. ;)

A picture of it standing with a static load should suffice.

feel free to test a nice convenient little wheel tom. then we'll know

missed this bit - the "correct" solution is dried nitrogen. but since i
don't have any, and i'll take normal air.

Come up with a few hundred millions dollars, and we can have that
arranged. In the meanwhile, buy extra grease - submerging your bearing
while fording is hard on them.

Why should I do YOUR work for you, "jim"?
So you admit that a very small amount of water is not so significant as
to make it worth your while to go to the welding supply shop for a tank
of compressed nitrogen? Despite water having a bulk modulus four orders
of magnitude greater than air? So relative proportions do matter?

Yes. And some of that water vapor in the air introduced into the shock

This from someone who has made a habit of stalking Jobst Brandt on
Usenet for some time.
Would the metallurgist even have a clue on how to go about designing a
bridge? Would they spend twice the funds to destructively test every
bridge built, then rebuild it?
Certain people have made things clear in their posts - unless of course
they are constantly playing the fool.

what? like the "analysis" that says that wheels "collapse" as soon as a
spoke goes slack?
you're clutching at straws, lightweight. put you money where your big

Ooooooooooh, insults!
"jim beam" criticizes Jobst Brandt for testing a wheel in a manner that
does not reflect the actual loads occurring during riding. Then "jim
beam" turns around and performs a test on a wheel that does not reflect
the actual loads occurring during riding, but claims that it is a valid
test. Bloody great mistake or hypocrisy?

And "jim beam" just repeats himself.
eh? i give you a photo of static because that way, the tensiometer does
not fall off. and it's guaranteed to show the missing spokes at the
bottom where they are not supporting the wheel. but the wheel continues
to rotate and support load. as you'd know IF YOU DID THE FREAKIN'
EXPERIMENT FOR YOUR LAZY-ASS SELF. goddamned lightweight.

This is less comprehensible than gene daniels' deliberate mangling of
the English language (and gene is much more entertaining).
No "jim", you are trying to prove a point with inadequate evidence.
that's it tom, deny reality. the way you succeed in deluding yourself,
maybe you'll next claim that spoke tension really /is/ "evidence" of
wheel strength?
ball's in your court. lightweight.
Psst... fellas. TRIM YOUR GODDAMNED CRAP!
Gee, thanks.
Why do you hold Jobst Brandt to a different standard than yourself, "jim"?
eh? i'm don't - so don't make false accusations! lightweight.

Yes you do. You complain that Jobst Brandt did not perform a realistic
test because he loaded the wheel with a torque concentric to the axle,
but then you claim your static test of a wheel with missing spokes
proves that those spokes are not needed to make the wheel functional.
> ps. why don't you answer the point? when are you going to test your

Why should I do your work for you?
again, you're putting false words in my mouth.
1. the pic is necessarily static because of the tensiometer. [duh]
2. it really doesn't matter /what/ the orientation is to evidence that
this wheel supports load, but the orientation shown is the worst possible.
3. that wheel is clearly not "functional". as i've stated before, you
wouldn't ride that wheel regularly - it's obviously hard to true, the
spokes make a heck of a racket, and things will just get worse as the
spoke nipples unscrew themselves. BUT, it supports weight, and will
ride - should you be so inclined.
and
4. most importantly, it doesn't "collapse" because some spokes are
missing and the others slack!!!

Double standard for Jobst Brandt - he needs to load the wheel according
to actual riding conditions, while "jim beam" does not. Sheeesh!
i said it supports load and will ride. you trying to misconstrue that
as "functional" is bullshit.

get your facts straight. i address "collapse", not long term
serviceability [obviously], and am drawing "collapse" conclusions
accordingly. jobst is addressing combination loading with single load
orientation - and drawing combination loading conclusions. if i were
trying to draw fatigue conclusions from a static load, that would be a
different matter, but i'm not, so don't make false accusations.

support static loads? How useful!

Why should I spend my money to do "jim's" work? "jim beam" is the one

Do not present arguments well, do you?
at this point you two should just get married.
then add one more for 'huit clois'.
I have never posted more than 250 times in one thread in an argument
with one person. This is not even coming close to that. ;)

Do you mean _disprove_ the point?

there's no need to be afraid and evasive if you think you have something
to prove tom. just go ahead and put your money where your mouth is -
like i already have.
You proved a bicycle wheel with missing spokes can support a STATIC
load. BFD for the real world.
so prove it doesn't work in your little world then! you're the one
bellyaching about it, the little guy that's all hat but no cattle.
so why don't you do it then?
Still trying to get others to do your work for you, "jim"?
eh? how could your failure to do your own experiments /possibly/ be
/my/ attempt to outsource /my/ experiments??? either you got
unbelievable chutzpah, or you're unbelievably stupid!
Why does "jim" promote a pointless experiment - what use is a bicycle
wheel with missing spokes that can only support static loads?
Why does "jim" keep on insisting I do his/her/its work for him/her/it?
your experiment, your work, chutzpah king!
why does the man with the hat but no cattle, propose experiments, then
refuse to undertake them? afraid of the result perhaps?
But I am not the one who made the claims about the missing spoke wheel,
and then refused to back them up with loading conditions that reflect
actual bicycle use.
Well "jim" (whoever you are), why did you post the results of an
experiment that does not duplicate the loads occurring in real riding,
but then criticize Jobst Brandt for doing the same?
So how far can you RIDE using that wheel, eh "jim"?
seems you don't read too well tom. go back to my discussion of
ridability of this wheel. then feel free to dispute my work by doing
your own experiments. if you have the wherewithal. i'm not going to
you your work for you.
Where?

Where is the "lightweight" comment?
for the purpose of demonstrating that it supports load, or for the spoke
nipples to unscrew and the spokes to fatigue? paper planes demonstrate
aerodynamic principles, but they are not a means of transportation.

I don't see why this experiment wasn't done with only one spoke (or a
pair) between the hub and the top of the rim. Statically this will
show the load hanging from the top and that the omitted spokes have no
purpose. It could also be used to prove benefits of paired spoking.
Jobst Brandt
LOL :)
How far to failure for the wheel missing spokes compared to an otherwise
identical wheel with a full spoke complement.

You could build an airplane using parchment covering, however.
you tell me! do the experiment!
Why? I am not the one claiming it is a functional wheel.

One spoke, like a Citroen steering wheel - Cool! You could get much more
than just a squirrel in a wheel like that!

er, we've already discussed "functional" - read up thread. /you/ want
to test "reliable", and for that, the ball is in /your/ court. i look
forward to your contribution.
I make no claims of expectation of the wheel being reliable. The static
test is rather pointless as regards real world use, no?
its point is to demonstrate that the wheel doesn't "collapse" with slack
and/or missing spokes, contrary to jobstian wheel theory. in that
regard, it is utterly /on/ point.
what's pointless is your constant lightweight bleating about trying to
prove it won't last in service, something that should be obvious to even
civil engineers that aren't typically familiar with "real world" testing.
Where is the contradiction to Jobst Brandt's wheel theory? As for
collapsing, "jim's" static test is not as severe for a front wheel as
hitting a pothole during hard braking would be (this may not be obvious
to the materials' scientist).

"jim" again shows his ignorance of engineering. The end products we
design are tested in use, and we are legally responsible to the owner if
they fail to perform as specified (another concept that appears to be
foreign to the materials' scientist).
jobst tells us that a wheel with slack spokes will, his word,
"collapse". it doesn't.

no shit sherlock. but my 205# ass sitting directly above a slack, spoke
deficient wheel defies jobstian "standing" theory.

raw nerve about civil engineers not testing their own products? or
you're worried about standing behind the words coming out of your own
big mouth because of legal liability? that's bullshit. you won't act
because you're a lightweight.
Under what loading conditions?

No, why should I spend my own money and risk injury to do "jim's" work
for him/her/them/it?

i'm sorry, did the wheel collapse? or is the picture a fraud and it's
actually supporting no weight at all?

you have a.s. you can't address reality. you're fixated by trivia and
paralyzed by your inability to deal.
But a static test is not representative of riding conditions, eh?
As to whether or not the picture is a fraud, that goes to the
credibility of the poster. How much credibility do sock puppets have,
anyhow?

Deal what (missing object)?
no? so when is the last time you tested a full size bridge to
destruction then?

see above.
Silly question. However, since the Tacoma Narrows failure, bridges have
been analyzed for BOTH static and dynamic loading conditions.

Well, people actually build stuff using my designs, and none of it has
failed yet.
Legally, you can not use deliverables from anonymous people for design.
I wonder why?

See above what?

They were analyzed for dynamic loads well before that. The dynamic
load of a steam locomotive was a challenging problem for engineers.
The stress in beams would change sign as the train crossed, causing
significant fatigue problems. I believe that early strain gauges were
invented for this purpose (measuring the strain in the bridge supports
during a train crossing).
However, that is a different issue than the aerodynamic loading
that cause the failure of the Tacoma Narrows bridge.

great - /you/ do your wheel testing and post your results then!!!
there's help available.
