Challenge Problems

Push your limits with challenges.

Question 1

A cylindrical tank filled with water experiences an increase in internal pressure causing stress in the tank walls. Calculate the normal and shear stresses along a horizontal cross-section of the tank if the internal pressure is known.

💡 Hint: Start by identifying the key stress components from pressure data.

Question 2

In a particular engineering application, the shear stress from viscosity dominates the forces acting on a fluid element. How would you analyze this using control volume concepts?

💡 Hint: Examine the relationships between shear rate and viscosity to evaluate stress appropriately.
