Hello there,
I am doing a project at the moment and it is close to finish. I have build a prototype for to do the compression and shear tests on the human tissue. before the prototype being build, all the test was performed using big test rig. Then it was decide to build a prototype to test the force and i have decide to use Strain Gauge to measure the test. Can I ask a few simple questions here and hope i can get some useful information here.
1.) I am using 2 plate to perform the compression test. the top plate is driven by a cable towards bottom plate (vertically). the cable was pull using a rotary switch. - where should i attact the strain gauge to get a more accuracy reading?
2.) the bottom plate will move in horizontal direction to perform a shear movement. and this is control by a pulling rod. same question again. where should i apply the strain gauge?
3.) is it possible to have 2 strain gauge in a same circuit board to get the two reading? - I need to build a smaller circuit if possible.
Wish to have your help here as i am a medic student, dont know much about the engineering part. Thanks in advance.
Regards,
Hunter
