9-3. Use the method of virtual work and determine the vertical displacement of point A. Each steel member has a cross-sectional area of 400 mm², E = 200 GPa. *9-4. Solve Prob. 9-3 using Castigliano's theorem. 9-5. Use the method of virtual work and determine the vertical displacement of point B. Each A-36 steel member has a cross-sectional area of 400 mm², E = 200 GPa. 9-6. Solve Prob. 9-5 using Castigliano's theorem. AG 30 kN 1.5 m E ooooo B 20 kN -1.5 m Probs. 9-3/4/5/6 D 2 m
