A rigid bar AB of length ‘L’ is supported by a hinge and two springs of stiffness ‘K’ as shown in figure. The buckling load Pcr for the bar will be-
  • a)
    1.0 KL
  • b)
    1.25 KL
  • c)
    2 KL
  • d)
    None
Correct answer is option 'B'. Can you explain this answer?

A rigid bar AB of length ‘L’ is supported by a hinge and t...

F = Kδ and F1 = K × δ/2
Now taking moment about A,
Pδ = F × L + F1 × L/2
⇒ P × δ = Kδ × L + K × δ/2 × L/2
⇒ P = 5KL/4
