In this question, we are interested inthe buckling of column, so we should calculate the moment of inertia (Ixx) or (Iyy) at the column,right?
The Attempt at a Solution
Why the author calculate (Ixx) and (Iyy) using the cross sectional area of beam?
is it wrong?
And for critical load applied at y-axis (Pcr_y) , why the Le used is 3000 , why not 250mm?[/B]
