Challenge Problems
Push your limits with advanced challenges
A hollow cylinder with an internal radius of 2 cm and an external radius of 4 cm is subjected to an internal pressure of 10 MPa. Derive the expressions for longitudinal and radial displacement.
💡 Hint: Ensure you apply the correct integration constants based on boundaries you've established.
If the material of the hollow cylinder has a significant Poisson's ratio, how would the behavior differ under high internal pressures?
💡 Hint: Consider how high Poisson's ratio affects both deformation types.
