Bigfoot snapped a 24" diameter Oak Trunk

To be fair, Bipto did not come up with the idea that Bigfoot ran 20 mph along a branch, crashing into the trunk, 45' above the base, it's 700 pounds causing enough to snap the trunk 24" diameter, at 24" above the base. Bipto (a member here) claimed that he witnessed the tree fall, and observed the large ape like creature run off.

This particular scenario was proffered by his supporters, who were trying to overcome objections that there was no way a 700 pound creature could break a 10000 pound plus, tree at it's 24" diameter base.
 
A question would be to the arborists/physics experts: How much force does a 50 mph wind generate against a canopy that measures 50' x 50' in cross sectional area?

Surely this must be far greater than the force generated by an impact of 20 mph by a 700 pound creature.

He stomped off in a huff from JREF as well...

My participation in this conversation has come to an end. It's clear that there are a few moderate people on this board interested in having a dialog, but the majority of posters aren't. At the end of the day, nothing I can say will move any of you in my direction and, since I've seen wood apes, there is clearly nothing you can say to make me change my mind regarding their existence. We are at an impasse. Further time and effort in my part is wasted. Surely, you can see that.

I'm disappointed that essentially no one here had anything to say about the one piece of physical evidence we have published thus far (namely, the hair sample). Also, nothing was said about the audio files I posted yesterday. Instead, much of the conversation has focused on trying to expose us as charlatans or hoaxers or worse. So be it. Most of you have already calcified your POV on the subject and there's really only one thing that will break you loose. Instead of spending my time here, I will go back and use it productively with my colleagues toward that end.

If anyone would like to continue a dialog, I'm available on Facebook (as is the TBRC and my podcast, The Bigfoot Show), our site has a contact form, and I'm still active on the BFF.

As Carol Burnett used to say, "I'm glad we had this time together..."

I did a little sample diagram, can anyone do anything with this?

OK,
It says 700 pounds mass, 20 mph velocity, impact at 45' above ground

:) Does it need to be? I can't think of anything at all it could say that would make the scenario plausible. I mean, crashing a Jumbo into the tree at the indicated point wouldn't break it off at the point shown.

Drew, the NAWAC really should hire you to illustrate their Wood Ape follies. There could be a coffee table book.

Nope. In energy terms, if you crash into the top of a tree you start putting energy into bending the tree. A charging Bigfoot has a decent amount of kinetic energy (here 25 kJ) but he's not the Incredible Hulk.

You're not thinking like a Bigfooter, here.

Then he remembered Garlank, the rockin', offspring of Krok and Zakrol, and patted Gablemp on the backside, saying 'You got this Bro...'.

Aha. His supporters were idiots then. They couldn't even frame the problem properly.

It would be possible to break a tree. I have done it myself on a smaller scale as I mentioned in an earlier post. Nothing that large, but it is just a matter of scale. Trees often break just due to wind alone. So it is possible. Actually under the right conditions you'd be surprised how easily a tree can break. But in the way it was described by his supporters? Ridiculous.

As I stated above..impact? ridiculous. But consider this. Wind blowing across a tree generates force on the tree and the tree bends. This releases some of the drag and the tree snaps back up. It is "waving in the wind". But a weight in a tree exerts more force as the tree bends due to leverage. Try this experiment. Hold a heavy book straight over your head, then gradually lower your arm with elbow locked till the book is straight out to your side, level with your shoulder. You can feel the force increase. So again, in the way his supporters describe? A horizontal impact at 20 mph causing the break? Ridiculous. But if the weight caused the top to bend far enough, much more force would be applied just by gravity. Add to that the weight of the tree itself as much of it approaches horizontal, and it is possible to snap the trunk. Realistically though. This generally happens in very tall thin trees with little branching except near the top of the canopy. In effect they are top heavy already. Forced to grow that way because of the other trees around them. But usually don't topple because the other trees help support them and prevent them from swaying too far. However, remove the other trees, and they will easily snap. You can see this effect very commonly beside a new logging road or power line cut through a forest.
