What type of motion the fluid element undergoes, when it changes from one position to another position, such that the angle between the two sides changes ?
Correct answer: D. Angular deformation
- A. Rotation
- B. Translation
- C. Linear deformation
- D. Angular deformation
Explanation
Angular deformation occurs when the angle between two initially adjacent sides of a fluid element changes. Rotation changes the element’s orientation without changing the angle between its sides.
