Question 2.
Define shear stress.
Show hintHide hint
Remember the concept of force and surface area.
3Question 3.
What happens to shear stress if the fluid viscosity increases?
- It decreases
- It remains constant
- It increases
Show hintHide hint
Consider what viscosity measures.
4Question 4.
Fluid deformation occurs continuously until what condition is met?
- True
- False
Show hintHide hint
Think about the characteristics of fluids under force.
Question 5.
A fluid with a viscosity of 0.9 Pa.s is coaxed between two plates 0.1 m apart. If the top plate moves at 2 m/s, find the shear stress.

Remember to rearrange and apply appropriate units.
Question 6.
During an experiment, a fluid at 20°C has a dynamic viscosity of 1.2 Pa.s. How much force is required to move a plate of area 0.5 m² at a velocity of 3 m/s if t = 0.05m?
