Hi all,
Quick question. Why is it that the maximum strain induced by strain guauges is when the strain guages are mounted at +/- 45 degrees to the nuertal axis?
My step-son has a piece of college work on shear strain guages, where one strain gauge is in compression and the other in tension.
Please be fairly basic in your replies...this REALLY isn't my field
Thanks in advance for your help.
