Question

The slenderness ratio of a column is defined as the ratio of its length to its

• A. Maximum radius of gyration
• B. Maximum lateral dimension
• C. Least radius of gyration
• D. Least lateral dimension

Answer 1

Answer:

C. Least radius of gyration

The slenderness ratio of a column is the ratio of its length to the least radius of gyration of its cross-section. It is used to find the design load and classify columns as short, medium, or long. Short columns have a slenderness ratio of less than 32, while long columns have a ratio of more than 120. The equation for slenderness ratio is $\lambda=\frac{ l_e}{ k_{min}}$
