5.19. Longitudinal axis of an orthotropic lamina makes an angle of 45 with the x axis. It is subjected to the following stresses: xyxy=20MPa=0=20MPa (a) Draw a neat sketch of the lamina indicating x,y,L, and T axes. Also show the applied stresses. (b) Calculate stresses along longitudinal and transverse directions. (c) Does the lamina fail under these stresses? Use the maximum work theory to predict failure and take the following strength values for the lamina: LULULTU=500MPa=350MPa=35MPaTU=10MPaTU=75MPa (d) Will the answer change if the direction of applied shear stress is reversed
