Consider a beam cross-section composed of an elastomer square stock with side length 200 mm and modulus E = 10 MPa. To the lower side of the bar we have glued a 1-mm thick sheet of steel (width 200 mm) whose modulus is E = 200 GPa. Determine the effective bending stiffness of the cross-section (EI)eff .
