A strain rosette was attached to the outer surface of stainless vessel when the vessel is in a stress-free state. The vessel was then put under a complex loading (pressure, bending and torsion) state. The train readings for the three strain gage elements in the strain rosette were recorded as: Ea=210, Eb=160, Ec-330, all in micro-strains. The mechanical properties of the stainless material are known: E=193 GPa, G=76 GPa, v=0.27, oy=205 MPa. Calculate the following: 1. Principal strains and in-plane maximum shear strain. 2. Principal stresses and absolute maximum shear stress. 3. The factor-of-safety based on the maximum shear stress failure theory. 4. The factor-of-safety based on the maximum distortion energy failure theory. 45° 45° b 45° strain rosette X
