[PSUBS-MAILIST] exotic steel

[hank pronk via Personal_Submersibles]

Scott,
I assume these calculations are all for an unreinforced sphere.  Is there any sense in using lighter shell material with reinforcing rings.  Is that possible with a benefit?

 I have
 a study that has the numbers somewhere, I just have to look
 for it. If I remember right it was about 200 lbs negative
 before anything else so ends up probably 1000+ heavy when
 you get all the stuff on it. I think the HY-100 was like 800
 positive before anything. I want to limit it to no bigger
 than a 6 feet diameter. My goal is to have a vehical no
 heavier than 10,000 lbs.Thanks,Scott
 Waters

 Scott,
 I am talking about 516-70, when you say way over,  what
 does that mean, and can increasing the dia compensate. I
 thought you were talking about 1,000 meters.  If you
 decide on 2,000 m then that is another story :-)  Seems
 your trip to see Karl has given you some things to think
 about.

  Hank,When
  you say traditional material are you talking 516 grade 70
 or
  HY100. If it is 516 grade 70 it becomes way overweight. If
  it is HY100 I have the sheets that Sean ran for me. The
 next
  question is do I want to aim for 1000 meters or 2000
  meters? Thanks,Scott
