Buckling of columns

The column is described as a vertical member of the structure that carries an axial compressive load, and buckling is a lateral deformation of the column under the application of load.

Question

A sheet of plywood consists of three equally
thick sheets, the upper and lower sheets
having their grain in the same direction and
the middle sheet with its grain at right
angles. The wood have a tensile modulus for
forces in the direction parallel to the grain of
10 GPa and in the transverse direction0.4
GPa. Determine the tensile modulus of the
laminate when loaded in a direction parallel
to the grain directon of the outer sheets.
