2.35 A rubber sheet of thickness t and area A is compressed as shown in the figure. All contact surfaces are sufficiently rough to prevent slipping. Show that the change in the thickness of the rubber sheet caused by the load P is (1+ v)(1 – 2v) Pt (1 – v) EA (Hint: The roughness of the surfaces prevents transverse expansion of the sheet.)
