Consider a steel (Young's modulus E = 200 GPa) column hinged on both sides. Its heights is 1.0 m and cross-section is 10 mm x 20 mm. The lowest Euler critical buckling load (in N) is ___.
-
- 3289 N
- 3289.8681 N
- 32.898 N
- 3298.8186 N
Correct Option: B
| Euler’s critical load = | |
| l2 |
| ⇒ | = 3289.8681 N | |
| 12 |
