A body is subjected to uniaxial tensile stress of 20 MPa in the y-direction as well as a temperature decrease of 10 degrees K. The material's elastic modulus is 90 GPa, the Poisson's ratio is 0.20, and the coefficient of thermal expansion is 12E-6 per degree K. What are the normal strains in the x, y, and z directions (microstrain units) ? Exx —102, € yу — 51, YY Ezz 82 -164, E yy –164, Exx = Ezz = -164 -164, E yy 102, Exx = Ezz = -164 164, Eyy - 102, Exx
