A two-dimensional strain field is found to be given by e_x =0.002, e_y = –0.004, and e_xy = 0.001. Incorporating the transformation relations (2.3.6) into a MATLAB code, calculate and plot the new strain components in a rotated coordinate system as a function of the rotation angle θ. Determine the particular angles at which the new components take on maximum values.
