The buckling load P = Pcr for the column AB in the figure, as KT approaches infinity, become
α π2EI L2
where α is equal to
-
- 0.25
- 1.00
- 2.05
- 4.00
Correct Option: D
Since stiffness KT ≈ ∞,
it act as fixed end. At the top end there will be only axial deformation. so it also cuts as fixed end.
| PCϒ = 4. | l2 |
∴ α = 4
