Correct Answer - Option 3 : 32 to 120
Explanation:
Slenderness ratio:
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 have a slenderness ratio of less than 32. Such columns are always subjected to direct compressive stress only.
- The medium column slenderness ratio is between 32 to 120.
- Long columns have a slenderness ratio of more than 120.
