What is buckling?
(a) Structural behaviour in which a deformation develops in direction of plane perpendicular to that of load which produced it
(b) Structural behaviour in which a deformation does not develop in direction of plane perpendicular to that of load which produced it
(c) Structural behaviour in which a deformation develop in direction of plane parallel to that of load which produced it
(d) Structural behaviour in which a deformation develops in direction of plane along that of load which produced it
I got this question by my college director while I was bunking the class.
My enquiry is from Plastic Theory topic in division Plastic and Local Buckling Behaviour of Steel of Design of Steel Structures
