Answer 1

ANSWER The main objective is to determine the critical buckling load for the column. Consider the free-body diagram of the column by giving the small displacement Hexe, Calculate the disturbing forces F and using the angle of deflection sine = 8 For the 1st spring, F = 8 K Fi = (6L) K For the and sping, F = 8₂ k & 2 = 0 4 4
