Question 1.
What is shear stress?
Show hintHide hint
Think about force over a surface.
Question 2.
What is a Newtonian fluid?
Show hintHide hint
Consider how common fluids behave under stress.
3Question 3.
What is shear stress?
- Force per unit area
- Volume per unit area
- Mass per unit area
Show hintHide hint
Remember, it’s about force applications!
4Question 4.
True or False: Newtonian fluids have a viscosity that changes with shear rate.
- True
- False
Show hintHide hint
Think about common fluids and their behavior!
Question 5.
A fluid has a shear stress of 12 N/m² and a viscosity of 3 N·s/m². What is the velocity gradient?
Show hintHide hint
Use the relationship of shear stress and viscosity to find the gradient.
Question 6.
Describe the implications for non-Newtonian fluids in engineering applications where fluid behavior varies with shear rate.
Show hintHide hint
Consider where different forces might apply.
