Strength of 3/4" iron pipe threads.

Thanks,

Boyntonstu

Here ya' go, Stu:

3/4" iron pipe threads produce 32,450 ksi inverted shear strength. That is,
assuming you've torqued the joint to a value between 86.5 and 86.6 ft-lb,
backed off a half-turn, and re-tightened by 11/16 of a turn.

Enjoy!

You can get at least 23.76% more than that if you use unobtanium pipe.

Even Better than that, if you fill the pipe with heavy water, its extra
gravitational attraction will lessen the "pull" of the earths gravity by
about .000258758 g/M/L. Note that if you put a resivoir above it, the
larger you make it, the more you can hang from the pipe. To acheive
the ultimate suspensive force, you must couple your resivoir to an
ocean,... or at least one of the great salty lakes. You must use PVC
pipe for this coupling though, or else the free gravitrons will adhere
to a metal coupling pipe and you wont get anywhere.
