Rectangle ABCD is scribed on the surface of a member prior to loading (Fig. P2.2). Following the application of the load, the displacement field is expressed by

where c=10-⁴ Subsequent to the loading, determine (a) the length of the sides AB and AD; (b) the change in the angle between sides AB and AD; and (c) the coordinates of point A.
