# Buckling: Quiz

Question 1: In ________, buckling is a failure mode characterized by a sudden failure of a structural member subjected to high compressive stresses, where the actual compressive stress at the point of failure is less than the ultimate compressive stresses that the material is capable of withstanding.

Question 4: A short ________ column is one whose slenderness ratio does not exceed 50; an intermediate length steel column has a slenderness ratio ranging from about 50 to 200, while a long steel column may be assumed to have a slenderness ratio greater than 200.

Question 5: The ratio of the effective length of a ________ to the least radius of gyration of its cross section is called the slenderness ratio (sometimes expressed with the Greek letter lambda, λ).
