1. For the elements shown in Figure P11–6, take the nodal displacements feel been strong to be

Determine the strains and then the stresses in the elements. Let E = 210 GPa and n = 0:3.

2. Figure P11–9 shows how stable and roll elements may be alike. What exclusion must be placed on the outside applied loads for this concatenation to be satisfactory?
