Another slack chain question

which is maths

this is man power over a thin piece of metal

sssttttrrrrreeeeeetttttcccccchhhhhhhhhhhhhhhh!!!

and this is a miss use of a word.

Hippy is right.

and this is a miss use of a word.

hmmm!

hmmm!

This does not invalidate my claim.

Chains don't stretch.

I have invited the mechanic at LBW to explain his POV.

Chains stretch. This term stretch refers to the traditional understanding, where an object under external torque forces, elongates due to this tension.

Nowhere does the term stretch involve or preclude the phenomenon of wear. If wear is the result of the torque forces, and the object elongates, it has stretched, even if its components have not. The links do not stretch, but the chain, which is the sum of the parts, has elongated....or stretched. It is possibly an optical illusion, except for the single fact that the elongation can be measured.

No, not stretched like leather or rubber, but the sum effect of the displacement of joints to links, creates the effect that can rightly be termed stretch. Just because the links can never stretch doesn't mean the overall item has not elongated under force. Because it has, and does, all the time.

Chains stretch. Links do not.

-999,999 to you others.

Except in engineering terms stretch (or, more accurately, "strain") applies to only a continuous body.

Link = single continuous body. Chain |= single continuous body.

In the great intellectual tussle between engineering and language, I come firmly down on the side of language. Could any concept be explained without a language? And since my language is English, I say that the understanding of the term stretch predates engineering, and if an engineer sought to convince me about words, I would laugh.

Anyone else want to make me laugh at them? Please, show your approval for the less important criterion. Chains stretch, but engineers wear jumpers.

they'll stretch in a hot wash too

chains lengthening due to wear which is not stretching.

Thanks for summarising.

hippy, you are the exception, and its understandable that Aussies aren't as familiar with the English language. Having a language of your own of course makes this simplicity to understand.

Chains stretch.

Shall I say it slowly for you, since you come from a land so far away?

;)

yeah, you tell 'im, gagz!

So, I should start using a chain wear gauge on a new chain should I? Because the action of taking it out of the packet might have stretched it? Okay.. sure.. you keep telling yourself that.

If you choose to pretend that chains do not stretch, I shall accept your argument, along with gravity does not exist.

Chains stretch. How many ways do you need to understand this? What are you? Fat?

is he fat :)

If you're trying to turn this into last post wins.. I'll have the last post and close the thread.

Fatty.

Riders often speak of "chain stretch" a technically misleading and incorrect term. Chains do not stretch, in the dictionary sense, by elongating the metal by tension. Chains lengthen because their hinge pins and sleeves wear. Chain wear is caused almost exclusively by road grit that enters the chain when it is oiled. Grit adheres to the outside of chains in the ugly black stuff that can get on ones leg, but external grime has little functional effect, being on the outside where it does the chain no harm.

thread ends.. Thankfully

hippy in all seriousness, I think even temporarily locking the thread was going too far.

There was only a jovial disagreement of semantics versus engineering, and no swear words were used, and no-one was maligned.

I like you personally, but that was a pretty shitty thing to do.

I wont post in this thread any further, and everyone is entitled to believe what they wish.

But that was really poor, poor, poor form.

I really pat my back for what I did here. Anyway, murtleflaps was later in on it.

I all seriousness I think you're a bit of a blouse for not even seeing the funny side of it.

Fucksake it's a fucking bike forum. Knickers twist, much?
