Challenge Problems
Push your limits with advanced challenges
A hollow cylinder is subjected to an internal pressure P and an external tensile load. Derive the overall relationship between σrr and σθθ through integration.
💡 Hint: Ensure to consider the boundary value at both surfaces.
Analyze a scenario where a hollow cylinder is twisted without any internal pressure. Explain the stresses present and derive conditions leading to a zero stress state.
💡 Hint: Visualize the cross-section before and after applying the torque.
