4. A triangular support bracket is shown in the figure. The bracket is modeled as a

plane stress problem, which is discretized into a two elements with 4 nodes. The

displacements at the nodes 1 and 2 are found to be

(u1 v1) = (0.00195 mm -0.00111mm) and

(u2 v2) = (0.000098mm -0.00055mm)

respectively. Find the stress and the

displacement vector at the center of the second element. The thickness of the

bracket is t=10 mm, the Young’s modulus, E=70,000 MPa and the Poisson’s ratio,

v= 0.3.
