Description: The questions below are based on Reading Assignment #1.
(1) Multiple Choice. What is the continuum hypothesis, on which the governing equations for fluid dynamics are based? (Pick the one best answer.)
(2) Multiple Choice. When forces associated with stress (that is, forces that act on the surface of an object) vary from one part of the object's surface to another, the object can undergo distortion. What are the two types of distortion? (Pick the one correct answer.)
(3) Multiple Choice. What information (constraints, conditions) must we specify as part of solving the governing equations to forecast/predict the future state of a fluid? (Pick the one correct answer.)
