A single ply of a certain graphite-epoxy composite with fiber oriented at 60° is in a planer state of stress. The strains in the xy coordinates are {e} = {0.012 0.002 0.0013. Find out if the lamina will fail according to maximum stress theory. The [Q] matrix for the lamina is [Q] = 120 3 0 3 10 0 0 07 Allowable stresses are OLU- 1950 MPa, Oru-50 MPa, o'LU-1400 MPa, O'TU-200 MPa TLTU=90 MPa.
