For the plane strain elements shown in Figure P6–9, the nodal displacements are given as u 1 = 0:001


For the roll clarify atoms shown in Figure P6–9, the nodal displacements are consecrated as

u1 = 0:001 in: v1 = 0:005 in: u2 = 0:001 in:

v2 = 0:0025 in: u3 = 0:0 in: v3 = 0:0 in:

Determine the atom stresses sx; sy; txy; s1, and s2 and the pre-eminent determination yp. Let E = 30  106 psi and n = 0:25, and use item brawniness for roll clarify. All coordinates are in inches.
