New Strength of materials Testing

How frangible does frangible need to be in order for 10 lbs of rocket to break apart upon hitting a human? And still be capable of withstanding flight stress? Frangible rocket that won't hurt anyone upon impact and a L1860...I don't see that combination being viable.

I thought we beat this horse into puree long ago?

White glue or contact cement. Maybe NAR and TRA can add that to NFPA-1127 :)

Which glue is best to let the rocket fall apart when it hits a human?

Magical adhesive that is stronger than epoxy with a speed/proximity to human being release feature.

Some epoxies are very strong but very brittle.

tabs in slots with a dab of post-it adhesive would about do it

(tap, tap, tap, is this thing on?)

on the temperature test page, the graphic link below the text starting with "All measurements were taken ..." and above the text starting with "The test was started at ..." is broken

the link which the graph icon, with a caption "Click here for graph", points to when clicked does not render in NS 7.1. Can you make this a JPG?

the same is true for the next graph

and the Brittleness section is incomplete

sorry you asked, eh? ;o)

The stuff 3M uses on the back of post-its. ZOr we can build all of our rockets like the "crash cars" we had as kids. THe ones that fell apart whenever they hit anything. Like the extes cato.

Right click and save link to desktop. Open from there.

Then the link text should say something as a user interface issue

d0h,

IMnsHO, that is insufficiently user friendly

I thought the Right to Keep and Bear Arms came from the Constitution; the reason to do so came from the Declaration of Independence. ;-)

Or as someone put it, "they put the second amendment in the Bill of Rights just in case the government didn't obey the other nine."

Actually from the "Bill of Rights", the first 10 ammendments to the constitution...
