Question:-
With one fixed end and other free end, a column of length L buckles at load P1. Mother column of same length and same cross-section fixed at both ends buckles Vat load P2. The ratio of P2/P1 is
Option (A)
1
Option (B)
2
Option(C)
4
Option(D)
16
Correct Option:
(D)
Question Solution:
Leq = 2l for one end is fixed and other is free
Leq = l/2 for both ends is fixed
Pcr = (p2El / L2eq)
Now (P2 / P1) = {2l / (l/2)}2 = 16
