1.	Euler critical load for column with both the ends hinged is given by(a) Pcr = 2π^2EI/L^2(b) Pcr= π^2EIL^2(c) Pcr = 2π^2EIL^2(d) Pcr = π^2EI/L^2This question was posed to me in an online interview.My question is from Elastic Buckling of Slender & Built-up Compression Members in division Design of Compression Members of Design of Steel Structures
Answer» The correct answer is (d) Pcr = π^2EI/L^2 For explanation: The EULER critical load for column with both the ends hinged is GIVEN by Pcr= π^2EI/L^2, where E is elastic MODULUS of material, I is moment of inertia and L is length of column.
