What is the primary failure mode of a long thin structure like a mast when subjected to compressive loads?
- Fatigue failure
- Yielding of the material
- Buckle instability (correct)
- Shear failure
Which factor contributes most to the failure of a long thin mast under compression?
Which factor contributes most to the failure of a long thin mast under compression?
- Environmental conditions
- Surface finish
- The length-to-diameter ratio (correct)
- Material strength
How does the geometry of a mast affect its stability under compressive loads?
How does the geometry of a mast affect its stability under compressive loads?
- Thicker masts experience less compressive stress.
- Mast geometry has no impact on stability.
- Longer masts are less stable due to increased slenderness. (correct)
- Shorter masts are always more stable.
