Problem 1 (30 pts): For the truss shown below, determine all member forces and nodal displacements. E=200 GPa and cross-sectional areas are enclosed with parentheses. Problem 2 (30 pts): For the truss shown below, determine all member forces and nodal displacements due to the combined effects of the load, member BE temperature increased by 30C and member BD is fabricated 12 mm too short. E=200 GPa and cross-sectional areas are enclosed with parentheses and the coefficient of thermal expansion is 11.6x10-6/C. 75 KN 1 B (1000 mm) 120 KN 54 3 m (1500) 4 m 6 m 1500) 1500) (1500) 1500 B 3 m A (1000) (1000) 60 KN (1500) A4 4 m (1500) (1500) | 2.5m.] 2.5m 11.25 m 2.5 m (1000 mm) E (1000 4 m 2 m Problem 1 (30 pts): For the truss shown below, determine all member forces and nodal displacements.
