To measure the principal strain in a structural member two strain gages are fixed and their direction is 30 degrees to known direction of principle
To measure the principal strain in a structural member two strain gages are fixed and their direction is 30 degrees to known direction of principle stress. The measured strains are 450 and (-) 32 microns, respectively. Given E= 210 GPa and poison ratio =0.3, Find the magnitude of principal stresses.
