1. Let x = f (X) be given by *2 = A2X2 + K2X, X'3 = 13X3. Compute the stretch ratio (equation 3.19 in book) for line elements originally in the directions of a) M = E, (M and E, are vectors) b) M = Ez (M and Ez are vectors) c) M = cos(0)E, + cos(0)E, (M. E,, and Ez are vectors) Show that all in-plane line elements experience the same stretch if 1, = 1, and *2 = 0. Likewise, show that these line elements do not change orientation if 1, = 12
