VI. A 5 mm thick, cross-ply laminate is constructed from 15 identical laminae, [0/90/0/90/0/90/0/0/0/90/0/90/0/90/0], having the same [Q] matrix and strengths given below. a) If a uniaxial load is applied to laminate, Nx, calculate the load at first ply failure using the maximum strain theory. 56 4.6 0 b) What is the maximum load this laminate can sustain?
