The two members shown are all pinned jointed made of wood having square cross sections of dimensions a x a. Determine the smallest value of a that will provide a factor of safety of 2.5 against buckling. Use E=12GPA for wood and assume the joint B is braced so that it can only move in the plane of structure.
