5. We have two simply supported beams, i.e., beam I and beam II. They are made with the same concrete and subjected to self-weight only. The span length and cross sectional area of beam I are the same as those of beam II. The difference is the shape of cross section as shown below, i.e., rectangular section in beam I and I-shaped section in beam II. q Beam I Beam II h [H (1) (10 pt.) Which beam has larger deflection and curvature? Explain why. 1 (2) (10 pt.) Which beam has larger compressive and tensile stresses at top and bottom fibers, respectively? Explain why.
