SD TRUSS PROBLEM WITH THE METHOD OF JOINTS

The truss structure ABCD is loaded with a concentrated force P = 2 kN applied at a 45 angle at joint D as indicated in the figure. All bars in the truss have equal cross sectional area and are made of the same homogeneous linear elastic material. The dimensions are H=3 m and L=8 m. Use the method of joints to obtain the axial forces in the bars and the Cartesian components of the reactions at the supports A and C.
