Which law/principle of solid mechanics is similar/equivalent to Newton's law of viscosity in fluid mechanics ?
Correct answer: A. Hooke's law
- A. Hooke's law
- B. Newton's second law of motion
- C. Archimedes principle
- D. Newton's third law of motion
Explanation
Newton's law of viscosity relates shear stress to velocity gradient, while Hooke's law relates elastic stress to strain. Both express a proportional stress-response relationship, making Hooke's law the solid-mechanics analogue.
