For the plane strain elements shown, the nodal displacements are given as

$u_1=0\mathrm{.}001in.,v_1=0\mathrm{.}005in.,u_2=0\mathrm{.}001in.$

$v_2=0\mathrm{.}0025in.,u_3=0\mathrm{.}0in.,v_3=0\mathrm{.}0in.$

Determine the element stresses ${}_x,{}_y,{}_{xy},{}_1,$ and ${}_2$ and the principal angle ${}_p.$ Let $E=30e6,v=0\mathrm{.}25,$ and use unit thickness for plane strain. All coordinates are in inches.
