Question: For the elements given in Problem 6.3, the nodal displacements are given as u1 = 0.0 in.............v1 = 0.0025 in.............u2 0.0012 in. v2 = 0.0

For the elements given in Problem 6.3, the nodal displacements are given as

u1 = 0.0 in.............v1 = 0.0025 in.............u2 0.0012 in.

v2 = 0.0 in.............u3 = 0.0 in...............v3 = 0.0025 in.

Determine the element stresses σx, σy, τxy, σ1, and σ2 and the principal angle θp. Use the values of E, v, and t given in Problem 6.3.
