1. The problem statement, all variables and given/known data

Neutron diffraction is used to measure the residual strains near to a weld in an aluminium plate. The aluminium has a young’s modulus E of 70GPa and a poisons ratio of 0.3. The three principal strains obtained are ε1= 2400 με ε2=0με ε3=-350με. What are the values of sigma 1 and sigma 2???

2. Relevant equations

Plane stress and strane equations

3. The attempt at a solution

Got an answer of an answer near to 212MPa and 83MPa

but not sure if its right
