Strength of Materials
Difficulty: Easy
Choose an option
-
AShort columns
-
BLong (slender) columns
-
CBoth short and long columns
-
DOnly weak columns irrespective of length
Answer
Correct Answer: Long (slender) columns
Explanation
ConceptEuler's buckling formula assumes elastic instability and is valid for columns with high slenderness ratio (long/slender), where buckling governs before material yield or crushing.
Final AnswerLong (slender) columns.
