A few weeks ago, I would have given you the same list. However, I have an employee working for me that has both a mechanical and civil degrees, but started off as an electrical major. He switched to mechanical from electrical, because electrical didn't provide enough of a challenge for him...
I just wanted to make sure that if any college kids were reading this that they didn't get any stupid ideas. I remember being a college kid and there was no telling what me or my friends would do given an intriguing idea. :)
L = length, feet
W = width, feet
DH = draft height, feet
R = 62.4 lb/ft3 (density of water)
GW = gross weight, lb
L x W x DH x R = GW
Therefore:
DH = GW / (L x W x R)
This assumes a rectangular "squared off" bottom, with no slope to the hull bottom at all. If there is slope...
BobG has an emotional affinity towards concrete :smile:
Ok, even if we considered concrete, the members would be so big that your payload would need to be reduced to accommodate the structure. There you go, BobG... :wink:
Structural aluminum generally has a higher strength than regular old ASTM A-36 carbon steel, and about the same as high strength steel. The trade-off is fatigue and sometimes product compatibility. Aluminum does not really have a fatigue stress limit that if you stay under that stress, it...
I can think of one more slight variation. Think about moving completely in and out of the 2D world and what the 2D being would see. It would be something like a MRI, where only a cross section of your body is seen at a time.
Of course, this thought experiment is slightly off. Remember that...
If you are standing a specified distance from a pretty girl, and incrementally move half your current distance toward her, it will hurt.
Sorry. It was all I could think of.
I'm sure he is thinking of a 4th physical dimension rather than time.
This 4th physical dimension to us would be similar to the 3rd physical dimension to a 2 dimensional being. A three dimensional being could, say, poke their finger in and out of the 2D world at various places, and at will...
Ya'll have missed one of the major legacies of the Manhattan Project. It left us a major nuclear waste clean up problem both at the Hanford site in Washington and Oakridge site in Tennessee. There's a little bit at Idaho National Labs as well. Billions of dollars are being spent to clean up...
