400 mm For the two-bar truss shown in the figure, using matrix analysis, calculate the following: 1. The displacements (x and y) of Node 2. 2. The forces of both elements. State if they are compressive or tensile. 3. All support reactions. For both members, take: Modulus of Elasticity: E = 100 GPa = 100 kN/mm Section Area: A = 100 mm. You can use kN and mm as your base units, for convenience (no conversions needed). 10 kN 1 300 mm 5 kN L=500 mm 2 700 mm 400 mm L=500 mm 3 What will happen if the support at Node 1 becomes a Roller (instead of pinned)? 300 mm M 100 mm
