1. For the elements shown in Figure P11–6, assume the nodal
displacements have been determined 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 solid and plane elements
may be connected. What restriction must be placed on the externally applied
loads for this connection to be acceptable?
