2 a) Figure 1 shows the orientation of the carbon fibre which is orientate at 0.A9 radians from the vertical plane. Draw and label the element's normal and shear stresses acting on the carbon fibre and determine the optimum orientation for the carbon fibre and the principal stresses based on the loading conditions shown.
