Practice Questions
Test your understanding with targeted questions related to the topic.
Question 1
Easy
What happens to shear stress in a fluid at rest?
💡 Hint: Think about fluid motion—if it's not moving, what happens to forces acting parallel to surfaces?
Question 2
Easy
What is gauge pressure?
💡 Hint: Consider how we compare pressures to the atmosphere.
