Question

In steady state conditions, the flow behavior is characterized by

• A. Stress alone
• B. Deformation rate alone
• C. Independent of stress and deformation rate
• D. Both stress and deformation rate

Hint:

Both stress and deformation rate are key factors in determining the flow behavior in materials, particularly in non-Newtonian fluids.

Answer 1

The Correct Option is D

In steady-state flow conditions, the flow behavior depends on both the applied stress and the deformation rate, and is often described using constitutive equations such as Newtonian or non-Newtonian models.
