Question for Mechanical Engineers

Hi,
I'm trying to get my head around a purely 'mechanical' issue: the resistance of a fully-tensioned length of 2" pitch ISO1275/216b bush-chain to bending or twisting.
I cannot find any published figures; but do suspect that the bending/torsion resistance is very large compared to the tension within the linear axis of the chain.
Does anyone have any useful pointers?
Thank you,

(Yes, there is a Propeller connection! It will be doing all of the data processing, listening to a wireless mesh network, parsing the data, then uplinking it over a 900Mhz connection, then recovering the data and forwarding it at a distant PC. But I've got to sort out the mechanical design before the Guv'nor will let me do the programming...)

Thank you - I had not even begun to consider 'wear and tear'!
In this application, I want to use the bush-chain to anchor sensors to steel pipelines: so once clamped up there will be no movement as such. But the chain will be good and tight, with special links carrying an M8 bolt-fixing to anchor my sensor.
