1. For the structure shown in Figure 1, determine (i) the unknown displacements at all the considered nodes, (ii) the strains as well as (iii) the stresses for each and every of the involved constant strain triangle (CST) finite elements. Lastly, provide estimations regarding iv) the reactions. Thickness (t) = 0.2 in, E= 30 x 106 psi, v=0.3 600 lbf 200 lbf 300 psi 12 in 6 in 200 lbf 4 300 psi El 2 12 in El 1 2 600 lbf 6 in Figure 1.
