When subjected to shear force, a fluida)deforms continuously no matter...
Explanation:
When a fluid is subjected to a shear force, it deforms in response to the applied force. The deformation of a fluid is characterized by the flow of the fluid in response to the applied force. The flow of a fluid is described by the velocity gradient in the fluid. The velocity gradient is the rate at which the velocity of the fluid changes with respect to the distance from a point in the fluid.
Continuous deformation:
When a fluid is subjected to a shear force, it deforms continuously no matter how small the shear stress may be. This is because a fluid does not have a definite shape or volume. It can flow and take the shape of the container it is in.
Newtonian and Non-Newtonian Fluids:
The behavior of a fluid under shear stress depends on its viscosity. Newtonian fluids have a constant viscosity regardless of the shear rate, while non-Newtonian fluids have a variable viscosity that depends on the shear rate.
In Newtonian fluids, the rate of deformation is directly proportional to the shear stress applied. This is known as Newton's law of viscosity. In non-Newtonian fluids, the relationship between the rate of deformation and the applied shear stress is more complex, and can be described by various models.
Conclusion:
In conclusion, when a fluid is subjected to a shear force, it deforms continuously no matter how small the shear stress may be. This is true for both Newtonian and non-Newtonian fluids. The rate of deformation depends on the viscosity of the fluid and the applied shear stress.

A fluid is a substance that deformed continuously when shear stress is applied to it irrespective of the magnitude of the shear stress. Because of the continuous deformation flow of the liquid can be seen. In other words, we can also tell that liquid can not sustain any shear load.
