Problem 2: The chart shows the results of tortional ring shear tests conducted on remoulded specimens of a clay at different effective normal stresses \( \left(\sigma_{n}^{\prime}\right) \). Draw the fully softened and residual shear strength envelopes of this clay. What would be the fully softened and residual shear strengths of this clay at \( \sigma_{\mathrm{n}}^{\prime}=120 \) \( \mathrm{kN} / \mathrm{m}^{2} \) ?
