A column has a rectangular cross-section of 10 mm × 20 mm and a length of 1 m. The slenderness ratio of the column is close to
-
- 200
- 346
- 477
- 1000
Correct Option: B
Slenderness ratio
| = | least radius of gyration |
| = | K |
where Imin = minimum area moment of inertia i.e. Ixx or Iyy, whichever is less.
For given section
| Imin | = 1667 mm3 | 12 |
| and ratio= | = 346 | 2.89 |
