Capacity of wood column calculator - Cornell University

The x-axis refers to the "strong" axis of bending, except in the case of 3-2x4's bolted together, where the y-axis is stronger (see Fig. 2a). Fig. 2b shows an example where different unbraced lengths apply to the two axes: sheathing nailed to the stud prevents buckling about the y-axis, but not the x-axis. In this case, one might..
