BCSB Collision Reconstructive Divison

# Thread: BCSB Collision Reconstructive Divison

1. ## BCSB Collision Reconstructive Divison

Lots (meaning almost all of you) on here are collision experts it seems.

Self educated in this mystic art of science and opinion. Some learn by doing.. as in crashing themselves. Lots of you fall into that category. Bonus to the young whippersnappers who get bikes and crash in year 1 of riding. Very comendable skills on the bike.

Others, have just learned via the internet. You gather the info in your little peabrain and make an estimation on what happened depending on the alignment of the planets, coupled with your internal desire to defend all things motorcycling. You know, those pesky car drivers - should be assumed at fault.

So... I thought we'd start a little group. THe BCSB Collision Reconstructive Division.

I just went to put my gym strip on, and noticed I have a 3 inch skidmark in my underpants I removed. The question is, at 156.7lbs, and an estimated impact approach angle of 70 degrees, +/- 69 degrees with my seat.. just how fast was I moving when the rubber hit the road, so to speak?

3. Newton's second law F=mA should be able to do this problem. also we need the coefficient of kinetic friction of this gym strip and your underpants!

i like how accurate you are..

4. v = (v02 + 2 · a · s)1/2 (1d) * Vindaloo

5. If you've ever stunted your bike, rather than just falling off it drunk in the garage again, you'd get a feel for how far you can actually skid the thing.

Circa 1999-2000 when stunting was getting pretty popular here, we used to do just that. Lock up the bike and see how far it takes to stop. Since this is what most noobs do anyway when panic braking, if they don't tuck the front and land on their faces.
10 or more of us have all had crashes or been to enough bike nights and paced off the distances the bikes have slid and asked the question, "How fast were you going" we actually can tell you by just looking now.

When Cory Lodge died on the Malahat on a GSXR 1000 years back, we paced off his skid. He probably was slowed down to about 200km/h when he piled on the rear and went straight off the road. Witness said he was tapped in 6th moments before, 299 indicated on the bike but 280 or so with the gearing that was on it. Took the police a week with a crack team from the collision responce team to figure it out.

Jay I've picked up a lot of bikes from accidents, I've seen as much broken plastic as the Chop Shop in Richmond (where my Buell ended up), I've seen how much damage can occur. I've seen how far a CBR900 slides up hill with frame sliders at 180km/h and I've seen one without the frame sliders. Goes farther on the sliders.

I'd like to think I know a little something about the topic. Which makes be laugh when some kid brings by his broken bike and tries to tell me it fell over in the drive way, yet has a circular scratch pattern down it. Or scratches running length wise not UP the side.

LMFAO, the last bit takes the cake.

Tee Pee (no pun intended, since it was a skidmark in my undies), I am crowning you as the head spokesman for our Collision Reconstruction Division.

Each time there is a crash, we are going to officially chime in on the thread. They will be official statements from the group.

We need experience like you that is for sure. I'm still not sure you can answer my question about the shitstains in my pants, and how fast my ass skidded agains the fabric to lay such a strip from my small dart... but anyhoo.

:P

I had deleted the thread actually, but some moderator found is amusing enough to bring back to rife! I better go shower... and yes, I'm going to clean my ass with the little pom pom thing my wife like to soap up with her smelly bath shit she uses. I'll give it a real hard digger and leave it on the shelf for the AM.

Please see my last post for more details of the streak, but the underpants are cotton, polo ralph lauren... and kenitic friction, or dry friction of my rear end to pants would have to be calculated using the coulomb friction model. You should also apply both of Amontons laws.

9. advise to you.... lay off the booze.

and that's coming from a russian.

10. This entire thread: I don't even.

Didn't you get the memo Nikolai? Hulk here doesn't drink, smoke or eat shitty food anymore. Say your prayers and eat your vitamins.

12. Subscribed lol!

13. I want in.

14. Humbly suggest a rename to "BCSB Committee of Reconstructive Analysis Professionals"

his underpants?

16. but wait. were you riding a v-strom when the skidmark occurred?
