Question 1.
Define the stress tensor.
Show hintHide hint
Think about how it relates to pressure and shear.
Question 2.
What are the two components of stress in the stress tensor?
Show hintHide hint
Consider the orientation of the forces.
3Question 3.
What does the stress tensor τ_ij represent?
- A representation of mass flow
- A representation of internal forces in a fluid
- A representation of temperature in a fluid
Show hintHide hint
Think about how elastic and viscous properties relate to stress.
4Question 4.
True or False: The stress tensor is only relevant in solid mechanics.
- True
- False
Show hintHide hint
Consider where stresses apply in fluids.
Question 5.
Given a cube of fluid, calculate the stress tensor components based on applied forces and explain their physical significance.
Show hintHide hint
Break down the forces acting on each face and relate them to τ_ij components.
Question 6.
How would the stress tensor change if the fluid's viscosity increases significantly? Discuss the implications on shear and normal stresses.
Show hintHide hint
Consider how viscosity influences fluid motion.
