_____________ forces do not act in case of fluid flow ?
Correct answer: B. Tensile
- A. Elastic
- B. Tensile
- C. Vibratory
- D. Centrifugal
Explanation
Ordinary fluids cannot sustain tensile stress, because they separate or cavitate instead of carrying a pulling force. They can exert pressure and viscous, gravitational, or centrifugal forces, while tensile stress is characteristic of solids or special structured fluids.
