3.2. Types of Motion or Deformation

Try these first

1. 1.

   Define translation in fluid motion.

   Hint

   Think about water flowing in a river.

2. 2.

   What is shear strain?

   Hint

   Consider how a deck of cards behaves when pushed.

3. 3.

   What type of fluid motion involves spinning around an axis?

   • Translation
   • Rotation
   • Dilation

   Hint

   Think of how a tornado moves!

4. 4.

   True or False: Shear strain results from forces acting perpendicular to a fluid's surface.

   • True
   • False

   Hint

   Remember the sliding cards analogy.

5. 5.

   Design a small-scale hydraulic system. Discuss how understanding translation and shear strain can improve design efficiency.

   Hint

   Consider the role of smooth versus rough surfaces in your design.

6. 6.

   Imagine a scenario where fluid is flowing through a curved pipe. Predict how rotation and shear strain will affect the fluid's velocity profile.

   Hint

   Think about how car tires grip the road during a turn.
