Find the theoretical displacements ( in x and y direction) and the reaction forces of a 7-bar truss structure shown below. Try to use the symmetry condition to simplize the analysis. Note that all bars have the same axial rigidity EA. 1 = 1m 85 P = 100 N L = 1 m A = 10-3 m² E = 70 GPa 60° 3 Pinned Roller P= 100N support
