A column of effective length \( 1000 \) mm and radius of gyration \( 44.7 \) mm has a slenderness ratio of nearest to
Answer: B
Correct answer: 22.4
\[ \frac{L_e}{r} = \frac{1000}{44.7} = 22.4. \] This is a low slenderness, so the column is short and the Euler formula would overpredict its capacity - failure would be by yielding or inelastic buckling rather than by elastic instability.
