i want to find the strength of a 3 dimensional structure..

consider a rollcage of a car.. i which the each member of the rollcage can withstand certain amount of load. I want to find out the load carrying capacity of each member.

If you "...find out the load carrying capacity of each member.", how will that define "...the strength of a 3 dimensional structure.."?

1: Construct 3 dimensional structure
2: Load structure X axis (pile rocks on it) until failure; record.
3: Construct identical 3 dimensional structure
4: Load structure Y axis (pile rocks on it) until failure; record.
5: Construct another identical 3 dimensional structure
6: Load structure Z axis (pile rocks on it) until failure; record.

This won't really be of any use but should be entertaining. Please report back here with your findings.

That is not a very scientific way of doing things. He should weigh the rocks first.

And I missed an opportunity to plug the LynDoor™ Industries RockRecorder®, useful in accurate recordkeeping when piling rocks on 3D structures.

Haven't you upgraded that system to RFID rocks yet?

Yes, we have. Thank you for reminding me.

The LynDoor™ Industries EarthGroup Rockpile Failure Index Device® is an instrument component that is included with a LynDoor™ RockRecorder®. Here is an image of the assembled device being used in comparator mode:
