According to Euler's column theory, the crippling load of a column is given by p = π^{2}EI/Cl^{2}. In the Euler's formula, the value of C for a column with one end fixed and the other end hinged, is 1/2.

Two closely coiled helical springs 'A' and 'B' are equal in all respects but the diameter of wire of spring 'A' is double that of spring 'B' The stiffness of spring 'B' will be __________ that of spring 'A'
