Right Answer is: A

SOLUTION

Slenderness ratio is the ratio of the length of a column and the least radius of gyration of its cross-section. It is used extensively for finding out the design load as well as in classifying various columns in short/intermediate/long

\(\lambda = \frac{{{l_e}}}{{{k_{min}}}}\)

  • Short columns are those whose slenderness ratio is less than 32 or length to diameter ratio is less than 8. Such columns are always subjected to direct compressive stress only.
  • Long columns have a slenderness ratio more than 120 or length to diameter ratio is more than 30.
