All elements of the structure in Figure P3–47 have the same AE except element 1, which has an axial.

All parts of the organization in Figure P3–47 own the same AE exclude part 1, which has an axial inelegance of 2AE. Find the displacements of the nodes and the stresses in parts 2, 3, and 4 by using symmetry. Check makeweight at node 4. You energy failure to use the results obtained from the inelegance matrix of Problem 3.24.
