Challenge Problems
Push your limits with challenges.
Question 1
Given a fluid with a known shear stress and pressure gradient, derive the total stress tensor in a control volume.
💡 Hint: Focus on combining the shear and normal stress equations into a tensor format.
Question 2
In a hydraulic system operating at varying atmospheric pressures, discuss how control volumes would be defined to isolate the internal fluid pressures.
💡 Hint: Consider how changes in external conditions demand adjustments in the definitions of your control volume.
