28. The frame shown in the figure is subjected to some forces at Nodes 2 and 3. The resultin displacements are given in the table below. Sketch the axial force, shear force, and bendin moment diagrams for Element 3. What are the support reactions at Node 4? Assume EI =

1000 N-m2 and EA = 107 m2. Length of all elements = 1 m
