Question

Which of the following are correct?

• A. The shear modulus of a liquid is infinite.
• B. Bulk modulus of a perfectly rigid body is infinity.
• C. According to Hookes law, the ratio of the stress and strain remains constant.
• D. None of the above.

Answer 1

Answer: (A), (B), (C)

The correct options are
A The shear modulus of a liquid is infinite.
B Bulk modulus of a perfectly rigid body is infinity.
C According to Hookes law, the ratio of the stress and strain remains constant.

Even a small stress cause large strain.
In the case of the perfectly rigid body, strain is zero.
