Question

Newton's law of viscosity relates

• A. Velocity gradient and rate of shear strain
• B. Rate of shear deformation and shear stress
• C. Shear deformation and shear stress
• D. Pressure and volumetric strain

Answer 1

Answer:

B. Rate of shear deformation and shear stress

Newton's law of viscosity relates shear stress and rate of shear deformation. The equation is $\tau = \mu(dU/dy)$ This law states that shear stress is directly proportional to shear strain rate.
