need a diy strain gage
(OP)
Hi,
Recently had an issue with a wear mark on the airframe on a helicopter. Thanks for all the help with that issue. It under control now. I'd like to put a strain gage on the airframe at the point of the wear mark just to make sure the applied forces are what I calculated them to be. I've done some searching on the web and found quite a bit on strain gages but am still a bit unsure how to proceed. Anyone know of an easy (not real expensive) way I can do this? thanks.

Any piece of wire can be a strain gage but, mounting, calibration, and measurement of the value is the difficult/expensive part.

also, with a bunch of work you can calibrate the local stress to known inputs and develop a better sense as to what would happen at ultimate.
