Question 1.
Define shear strain in simple terms.
Show hintHide hint
Think about angles and how they change.
Question 2.
What does vorticity measure?
Show hintHide hint
Consider rotation in fluids.
3Question 3.
What is shear strain?
- A measure of fluid density
- A measure of angle change due to deformation
- A measure of fluid temperature
Show hintHide hint
Remember that it relates to angles.
4Question 4.
Is vorticity related to fluid motion?
- True
- False
Show hintHide hint
Think about fluids that spin.
Question 5.
A fluid flowing through a pipe exhibits a shear stress of 800 Pa. If the viscosity of the fluid is 0.2 Pa·s, determine the shear strain.
Show hintHide hint
Make sure you remember the basic relation between stress and strain.
Question 6.
Describe how understanding shear strain can help engineers design better fluid transport systems.
Show hintHide hint
Think about the implications of strain on material choices.
