Challenge Problems
Push your limits with challenges.
Question 1
Given a thick-walled cylinder with an inner radius of 10 cm and a wall thickness of 2 cm subjected to an internal pressure of 3000 kPa and an external pressure of 1000 kPa, calculate the radial and hoop stresses at the inner and outer radii using Lame's equations.
💡 Hint: Set up two equations for internal and external conditions to solve for constants A and B.
Question 2
Why might a thick-walled cylinder fail if only thin-walled assumptions are applied? Discuss the consequences of this miscalculation.
💡 Hint: Consider how stress affects material strength and structural integrity.
