Re: Solid as a block
Add a bit of lamination to the proceedings and you begin to enter the realm of immensely strong structures - the same as if you excavated from a solid block (stronger in fact - a solid block of wood has a grain along which you can get splits and cracks propagating. Not so with laminates)

Care to show your calculations that would support this assertion?

also:
What is "gopher" wood?
What is its Ultimate Strength in Tension, Compression and Shear?
What is its Yield Strenght in Tension and Shear?
What is its Modulus of Elasticity?
What is its Modulus of Rigidity?
What is its Coefficient of Thermal Expansion?

they may have said the ark was self righting

For them to know that, they'd have to have a good idea about the mass of the ark. And since nobody has been able to come up with a sample of "gopherwood" or any of it's physical properties, this is all just talk emanating from a dorsal orifice.

A look a the density of wood shows us that we would be very safe in assuming (and it makes explaining easier) that the arks wood was about as half as dense as water. (the figures here are density relative to water which is 1000 kgs/m3)

What is the density of "gopherwood"? Can you provide any of it's physical properties?

Thus for every animal (approximate density the same as water) you need to excavate twice the animals volume out of the wood in order to maintain the animal filled ark half in/half out of the water

How many animals were on the ark? Of what sizes? If you're going to remove twice the volume of animals you need to know the total volume of animals.

Is such a beast going to capsize? I think not.

Can you provide any calculations to support your thinking?

You talk technolgy as if anything here was super-complex going on here

Well seeeing as no wooden boat of the ark's alleged dimensions has been constructed calling it "complex" isn't that far from reality.

This is a debate forum - not analgazing.

This is the science side of the debate forum, calculations and requests for them are to be expected.

If most all woods in the world have a density half that of water then the onus is one you to come up with a reason to think gopherwood is summit else

Seeing as nobody can provide a sample of "gopherwood" or any of its physical properties, setting it's density to be the average of known woods is a big leap of faith.

My, you are getting desparate...

What about this is desperate? I want to see if:

VTotal - 2VAnimals > 0

So if the ark's dimensions are: 450' long, 75' wide, and 45' high
Then VTotal = 450 X 75 X 45 = 1518750 ft3

and VAnimals = NAnimals X VAvg Animals

We therefore need to know: NAnimals and VAvg Animals, which is why I asked the question.

Surely you're not afraid of a little math?

Edited by DrJones*, : it needed to be mathier

Edited by DrJones*, : also needed gud spelin
