Big Snatch

[Stephen Blair]

Hi Joe and Codz.

 

It's clear on your second video you guys knew what you were doing, that was a big horrible tree.

 

On the first video, if you thought it was going to work, then on that occasion I don't think you knew what you were doing, and the big snapped rope proves it.

 

If you guys were doing it as a stunt to show it wouldn't work, then you pulled it off 100%.

 

I just don't get why someone could be bothered going to all that work, but hey that's just me, you guys have taken offence to me comments, so I apologise

The whole point was an experiment,no-one knew what was going too happen and the workshop had in depths conversations giving there reasons why it would hold or fail.

If Lumberjake or anyone else can give me fall distance before arrest, and assuming the estimated weight of the "snatched" trunk is correct.

It is perfectly simple & straightforward to work out the forces involved and energy dissapitated.

F=ma an all that (Force = mass times acceleration)

kinetic energy =1/2mv2(squared)

I was a trifle surprised the rope failed, but as mentioned somewhere above almost certainly due to the 180 deg through the big shackle, scourging/abrading/heating, causing failure.

I suspect a (correctly sized) pully block would have made a significent difference.

PS.

( I bes a final year failed:blushing: civil engineering student )

If the rope hadn't of snapped then this might have been a video of a climbers death, I don't understand the point to this experiment. Snatching that size timber on that stem, root plate movement and possible hidden stem weaknesses would have been my first concern, rope failure last. Still entertaining to watch though, that climber must have balls like boulders...

No one was up the tree as the piece went over.

I don't think the climber was on the stem when it was pulled off.

JHC!

That much was clear............pulledoff by a UTE etc............. and the whole set-up was well managed..............imnsho

wtf

are some of younz getting yer knickers in a twist fer.

As the man said AN EXPERIMENT!

which if nowt else proved what DOES NOT WORK.

cheers

Totally missed that, watching it on a small screen. I still enjoyed it though.

[Jake Andrews]

I don't think any one called stay on the stem if they wanted too,there's not a flip line on the market that would be long enough too accommodate there cojonas!!!!
