Using superposition of the stress field (8.4.15), develop solution (8.4.18) for the equal but opposite biaxial loading on a stress-free hole shown in Fig. 8.15A. Also justify that this solution will solve the shear loading case shown in Fig. 8.15B. Construct a polar plot (similar to Fig. 8.13) of σ_θ(a,θ)/T for this case.
