Topic: Machine Design
For thin cylindrical shell structures loaded in compression, the design is based on
- A. Yield strength of material
- B. Ultimate strength of material
- C. Buckling strength of the structure
- D. Shear strength of the structure
Answer: C. Buckling strength of the structure
Explanation: Thin and long cylindrical structures under axial compression are prone to failure by buckling before they reach their yield strength. Therefore, buckling strength is the controlling design consideration.
