Use ANSYS to determine the first two mode shapes and
natural frequencies for the plane stress problem shown in Figure 10.18 for a =
b = 1, E= 1, _ = 1/3, _ = 1. Use the four-node Plane 182 element and
a 10 × 10 mesh. Determine the lowest two frequencies and view the mode shapes.

Load Step Summary.) Record the x component of displacements of nodes on the
loaded edge for each mode for use in problem 7.
