4. Longitudinal axis of an orthotropic lamina makes an angle of 55 with the x-axis. It is subjected to the following stresses shown in the figure. (a) Calculate stresses along longitudinal (L) and transverse directions (T). (b) Does the lamina fail? Use maximum strain theory to predict failure. Take the following material properties and strength values for the lamina: E1=58.1 GPa, E2=13.8 GPa, G12=5.3 GPa, v12=0.293 G-500 MPa, -10 MPa, =350 MPa. =75 MPa, TL-35 MPa.
