Question

For a circular column having its ends hinged, the slenderness ratio is 160. The 1/d ratio of the column is

• A. 80
• B. 57
• C. 40
• D. 20

Answer 1

The correct option is C 40

Slenderness ratio, $\lambda =\frac{l}{r}$
where $r$ is the radius of gyration.
$r=\frac{d}{4}$
$\therefore \frac{l}{d}=\frac{160}{4}=40$
