Q: When a compression member buckles at the buckling load, it reaches a state of ...
  • A. elastic instability
  • B. elastic stability
  • C. inelastic stability
  • D. plastic instability
Correct Answer: Option A - Instability of compression member– The stability loss under compressive load, is usually termed structural or geometrical instability commonly known as buckling • Generally, when a compression member buckles at the buckling load, it reaches a state of elastic instability. • Instability is a condition wherein a compression member loses the ability to resist increasing loads and exhibits instead a decrease in load carrying capacity.
