Multiple-choice question: Two rods are bonded together, with the cross-sectional dimensions as shown in the figure. The elastic modulus of rod 1 is E1, and the elastic modulus of rod 2 is E2, with E1 = 2E2. If an axial force F acts at the centroid of the cross-section, the deformation of the member is ( ). A. Tensile and upward bending deformation B. Tensile and downward bending deformation C. Bending deformation D. Tensile deformation Answer: A Hint: Extra rewards will be given to those who can explain the solution process; the answer can be found in the response!
