WebBuckling (Columns With Other End Conditions): However, in many engineering problems we are faced with columns with other end conditions. The first condition we would like to consider is a column with one fixed end and one free (unguided) end. By observation we see that this is identical to a pinned end column with a length of 2L. WebThe column must carry an axial load of 40 kN without buckling. Using a factor of safety of 5, calculate the dimensions of the tube if the one end is fixed and the other end is free. Use the Euler formula and take E = 200 GPa. The buckling load is equal to, 40 x …
