In a material in a state of plane strain, it is known that the horizontal side of a 10 × 10-mm square elongates by 4 μm, while its vertical side remains unchanged, and that the angle at the lower left corner increases by 0.4 × 10^{-3} rad (Fig. 7.67). Determine (a) the principal axes and principal strains, (b) the maximum shearing strain and the corresponding normal strain.
