the nodal displacements are For the plane strain elements shown in the Figure given as (4, 4) uj = 0.001 in. 0.005 in. U2 = 0.001 in. = 0.0025 in. Из 0.0 in. V3 = 0.0 in. U2 = 2 (2, 2) (4, 2)...

Please show each and every step in detail. Dont miss any steps and highlight the final answer.
Thanks!

Extracted text: the nodal displacements are For the plane strain elements shown in the Figure given as (4, 4) uj = 0.001 in. 0.005 in. U2 = 0.001 in. = 0.0025 in. Из 0.0 in. V3 = 0.0 in. U2 = 2 (2, 2) (4, 2) Determine the element stresses ox, Gy, Txy, O1, and o2 and the principal angle Op. Let E = 30 × 106 psi and v = 0.25, and use unit thickness for plane strain. All coordinates are in inches. (b)
