Questions and Answers

What is the primary factor that can lead to the failure of a long thin structure under compressive load?

  • Material fatigue due to cyclic loading
  • Excessive tensile stress
  • Shear stress exceeding material limits
  • Buckling caused by lateral instability (correct)
  • Which failure mode is most relevant for a mast subjected to compressive forces?

  • Bending failure under transverse loads
  • Fatigue failure from repeated loading
  • Elastic buckling due to compression (correct)
  • Torsional failure at joints
  • When considering the design of a mast, which aspect is crucial in preventing failure under compressive load?

  • Increasing weight to enhance stability
  • Minimizing all lateral loads at the base
  • Choosing a thicker material to prevent bending
  • Optimizing the height-to-base ratio (correct)
