Question

+The four-bar truss shown in the figure is made of elastic-perfectly plastic material. Each bar has the same cross-sectional area A. If the truss is loaded just to the flow limit (p = pu) and then unloaded, find the residual stresses. Length of bars AE and AD is L and that of bars AB and AC is 2L. Draw the variation of load P versus the horizontal displacement at joint A for the truss shown in the figure. Each bar has the same cross-sectional area A and is made of the same elastic-perfectly plastic material. The diagonals are not connected to each other. Assume that buckling of the compression members is prevented.
