A square plate with an edge length 0.9 m is simply supported

A square plate with an edge length 0.9 m is simply supported on all edges. The plate is made of a material with density 4300 kg/m, Young' s modulus 130 GPa and Poisson ratio v = 0.3. The plate thickness is 6 mm. The plate is loaded with a compressive load P on the left and right edge. Calculate the magnitude of the buckling load in N. P= N
