Effective Length of a Column

- The effective length of a column is the length of an equivalent pin-ended column that would buckle under the same load as the actual column.

- It is influenced by the end conditions of the column, which can be fixed, pinned, or free.

- If the column is effectively held in position and restrained against rotation at both ends, then the effective length is half the actual length of the column.

Explanation of Option B

- Option B states that the effective length is L/2, which means half the actual length of the column.

- This condition of the column is achieved when the column ends are effectively held in position and restrained against rotation at both ends.

- When a column is restrained against rotation at both ends, it is equivalent to a pin-ended column with a length of half the actual column length.

- Therefore, option B is the correct answer to the question.
