For the plane strain elements shown in Figure P6-10, the nodal displacements are given as

u1 = 0.005 mm............v1 = 0.002 mm............u2 = 0.0 mm

v2 = 0.0 mm...............u3 = 0.005 mm............v3 = 0.0 mm

Determine the element stresses sx, sy, xy, s1, and s2 and the principal angle u p. Let E = 105 GPa and v = 0.3, and use unit thickness for plane strain. All coordinates are in millimeters.
