3 cards from this section. Quick, good the night before a test.
Define viscous stress in your own words.
Consider what happens when you try to stir syrup.
What does isotropic mean in the context of fluids?
Think of how air behaves regardless of which direction you push it.
What does Stokes' first postulate state about viscous stress?
Think of how stress increases with deformation in simple terms.
True or False? The properties of an isotropic fluid change with direction.
Consider if you would feel different forces in all directions.
Analyze a situation where a liquid in a tank is experiencing both hydrostatic and dynamic pressures. How would you derive the total pressure at a point within this fluid?
Identify the forces active when diving into the fluid and consider depths.
Consider a slab of gelatin as a non-Newtonian fluid. How would you calculate its viscous response under applied strain?
