Questions and Answers

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?

  • 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?

  • 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.
