Author | Topic: About that Boat - Noah's Ark | |||||||||||||||||||||||

quote: Hmmm... several times the current volume of the ocean. Surely you know that?
quote: Really? In my post, I stated 'from whatever source.' You quoted the passage, so where did you get this idea? It does not matter what the source of the water was. That much water coming onto the surface in such a short period of time would create hurricane-like conditions. Temperature and pressure differentials would whip things into a frenzy. This on top of the more typical damge caused by the massive flash flooding. Have you ever witnessed a flash flood? These things topple concrete and steel structures.
quote: You are loosing credibility. 1) ... a reference to an archaic cosmology, probably derived from the existence of water tables-- waters under the earth. I suppose we can call them springs. Water flowing rapidly out of a spring will cause just as much damage as rain. It isn't the falling rain that does the damage. The damage is done by water's piling up on the ground, flowing towards the low-points, causing mud-slides, and etc. 2) What in the hell would you call water falling from the sky if not rain? Not to mention that God specifically threatens to make it rain-- Genesis 7:4.
quote: It tells me that the ancient Isrealites had a terrible understanding of meteorology. ------------------

quote: You certainly implied as much. Remember, you brought this up to counter that the ark met with rough seas.
quote: The Hebrew is 'ruach.' The word has a great many connotations most of which do not concern wind per se but spirit. It is the same word used in Genesis 1:2. "And the Spirit of God moved on the face of the waters." Claiming this means 'high winds' is stretching it a bit. It would be more accurate, but less poetic, the translate it as "God's magic."
quote: Or to the common knowledge that there is water under their feet if they dig a little.
quote: Come on! You are adding so much interpretation to the Bible I can hardly see the Bible any longer. The event occurs as a result of God's threatening to make it rain. Put the two together. That, and the windows idea is common to other mythologies of the time and place. It was believed that there were windows in the sky that keep water from falling down.
quote: And THIS would not be as damaging as a hurricane???? Bud, you've just said "It wasn't something rough like a hurricane, but rather something gentle like a TSUNAMI." Are you serious?
quote: It would have occurred. You'd have swells hundreds of feet tall-- just a guess. ------------------

Lets see...
Under most conditions of loading, the worst stresses in a beam are imposed at right angles to the direction of loading... Right angles. That would be sideways. In other words, this type of load would be caused by waves smashing into the side of the boat. The only calculations you made, that I can tell, are of the boat's lengthwise bowing-- ie. bow to stern hogging. Also, I notice that the author is discussing beams, not the whole ship.
quote: The author wouldn't be talking about steel would he? Steel has an enormous shear strength compared to wood. Shear may well be a minor problem with steel hulls. This does not mean it is minor with wooden hulls. Again, your are failing to consider the differences in materials. What happens when you bend a nail? It bends. What happens when you bend a toothpick? It breaks. See the difference?
quote: As I remember you've ignored too many variables for any of your calculations to be worth considering.
quote: Maybe you need a primer on stress.

quote: ... you may be the only one since 1917.
quote: ... in 1917. I haven't seen any proof of his theories.
quote: Lol.... so did Utnapishtim. Realistically, economics would have been a big problem for Noah. He and his sons couldn't have done it alone, and employees need pay. Even slaves need food. Noah was a nomadic herder. They are not known for accumulating wealth.
quote: Somehow? Not much of an argument. In fact, it isn't even admissable. The issue is whether or not the ark is possible. By claiming he must have solved the problem because he built the ark, is assuming that he built the ark and it worked. The argument is circular. By the way, where are those really big trees? ------------------

quote: Are you absolutely sure you know my allegiances? My comments about the falling rain not causing the damage was a response to the implication that the flood wasn't violent because not all of the water fell from the sky. Mine was a simple observation. Rainfall doesn't smash houses. One can stand in the heaviest downpours and suffer no harm, but that water accumulating on the ground and rushing downhill will cause damage. Thus, claiming the flood wasn't rough because it isn't all rain, doesn't work. The damage done by floods isn't the falling rain per se, but the collected water moving around on the ground. Of course, you are right. All that energy would add up to a lot, but I wasn't interested in getting that complicated. Several people have noted that all of this activity would whip up the mother of all hurricanes though. ------------------

quote: Still, I haven't seen any proof of his theories. And, in fact, neither have you. What you've got here is basically an appeal to authority. No dice. By the way, as a carpenter, I have had more than one qualified engineer present me with diagrams of objects that are physically impossible to build in a three dimensional universe. And I have seen a lot more things on diagrams that are dead obviously moronic to anyone who actually has to build the damn thing. Guess what? New buildings and bridges fail. Those buildings and bridges were designed by qualified engineers and the numbers all worked out just fine. But they failed anyway. hmmm..... So, engineers aren't gods and I have little confidence in diagrams that have not been put to a real world test.
quote: Big deal. I grew up around trees just as large. They aren't large enough to provide 450' timber. You point to a tree that starts at 4' and tapers to 2.5 over 120'. That is a 1.5' drop over its length. This means that at 240' the tree would be 1' thick and at 360 it would be -.5. We are still 90' short of 450'. How does this support your point? The six foot stump? It would be 4.5 at 120', three feet at 240', and foot and a half at 360'. A foot and a half is the one-cubit mark and, if I remember right, that is the width of your timber. Still 90' shy. At 480' we'd be at zero, so at 450 all you have is a twig. And that is assuming a constant taper all the way-- big assumption. Not a lot of trees follow that pattern. ------------------

quote: Then the author can't write, or you are confused. I'd bet on the latter. Tell me, the load is vertical. Right angles to vertical would be what? Lengthwise or crosswise. Now, imagine a 2x4 set on its edge and loaded at the middle. Is it stronger if you push on the ends and toward the center, or if you push sideways at the middle? Answer: It is strongest when you push at the ends and very weak when you push sideways at the middle. So, how in the hell is sideways not the weak direction. Lumber works this way, trusses work this way, I-beams work this way.
quote: It seems that you are talking about dead loads in a stable environment, not live loads in the equivalent of an earthquake. Why you think this is an adequate analysis is beyond me.
quote: You've got to scan those diagrams.
quote: Well, no kidding!!! But scaling up does not alter the inherent properties of the material.
quote: That would be a good idea, but you don't seem to be willing to do so. Here are some more things you've not considered.

quote: You REALLY should read some of my posts.
quote: If we are going to go with the Biblical account, we don't actually know how much rain fell. The Bible makes the weird statement that water rose from beneath the Earth as well. The objection was made-- not by me but by someone who really is a creationist-- that this water from the deep would negate the damage caused by the flood. Thus, my reply that with normal rainfall, the damage is not done by the falling rain but by the movements of water on the ground. Thus, water from any source would be damaging. This does not challenge any of your considerations and calculations, which I find interesting. I hadn't before thought of the sheer force of the falling water. However, it doesn't matter. Within the context of the discussion we can't assume that all of the water fell as rain. We can't really assume any figure for the rain or for the springs of water from the earth. All we know is that total volume must cover the Earth. ------------------

quote: I did not ask that. I wouldn't expect it. However, you missed the mark by so far, it leaves me a bit speechless. I can't imagine how anyone could take me for a creationists. I'm not angry about it. It is much to bizarre to make me angry.
quote: The case to which I was responding was dangerously close to what you describe, or seems so to me. So I cut to the chase and went with "even if the water started on the ground..." ------------------
