The cross-sectional area of each member of the truss shown in the figure is A = 400 mm² and E = 200 GPa. (a) Determine the vertical displacement of joint C if a 4-kN force is applied to the truss at C. (b) If no loads act on the truss, what would be the vertical displacement of joint C if member AB were 5 mm too short? 3 m A -4 m- 4 kN -4 m B

For the roof truss shown in Figure P3-48, use symmetry to determine the displacements of the nodes and the stresses in each element. All elements have E = 210 GPa and A = 10 104 m2. 20 kN 20 kN 20 kN 4 m 80 8 m -8 m Figure P3-48
