a. A new structure with a similar setup but different materials is built as shown in the image (Figure 1). This time, rods I and II are made from glass with Eg = 60 GPa and ?g = 0.2. Rods III and IV are made from bronze with Eb = 100 GPa and ?b = 0.34. The applied force is P = 65 kN, each rod has a cross-sectional area of A = 7 cm2, and the vertical connecting bars are rigid and cannot rotate. What are the lateral strains in rods II and III?
