Problem 13.40 The strain gauge rosette shown below is mounted on the outer wall of one the Atlas launch vehicle's nozzles where the material is in a homogeneous state of plane stress. The strains measured by the rosette are &a=0.0053, &b=0.0038, and &c = 0.0029. The modulus of elasticity and Poisson's ratio of the material are E = 70 GPa and v= 0.33. What are the components of plane stress?
