Show answer and explanation

Correct answer: (D) Pure shear

Explanation

The zero centre means the two in-plane principal stresses sum to zero. Nonzero radius gives equal and opposite principal stresses,which can be represented as pure shear on axes45° from the principal directions. **Answer:D**. Equal biaxial stress would give a point rather than this circle.
