The cube is subjected to a compressive load of 140 N in the x direction. The properties of the composite material are: E-155 GPa, E-12.10 GP E-12.10 GPa, v0.248, 0248, and v0.458 Determine the changes in the cube dimensions, knowing that (a) the cube is free to expand in the y and z and when (b) the cabe is free to expand in the z direction, but is restrained from expanding in the y direction by two fixed frictionless plates 140 kN (United States) A 140 kN Fixed frictionless. plates, 140kN 60 mm 60 imm 140 EN 60 min (b) YEX
