A column is fabricated by adhesively bonding two aluminum faceplates to a foam plastic core as shown below Note that there are only left and right aluminum plates (with no front and back plates). The foam plastic core has a square cross-section with elastic modulus Ef = 1080 MPa. Determine the stress in the aluminum plates, the stress in the foam core, and the displacement of the column under the action of the applied force. Note: Express tensile stresses as positive (+) and compressive stresses as negative (-). F
