Question: Determine joint displacements and axial forces in the truss shown in Figure. Note the diagonals are not connected to each other at their crossing. The cross-sectional area of vertical and horizontal members is 30 x 10-4 m2 and that for the diagonals is 10 x 10-4 m2. All members are made of steel with E = 210 GPa. The load P =20 kN. The dimensions in meters are shown in the figure.
