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.

can someone help me how to find out the strength 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:
