A thin square plate in biaxial stress is subjected to stresses (x and (y, as shown in part (a) of the figure. The width of the plate is b = 12.0 in. Measurements show that the normal strains in the and directions are (x = 427 ( 10-6 and (y = 113 ( 10-6, respectively.
With reference to part (b) of the figure, which shows a two dimensional view of the plate, determine the following quantities: (a) the increase (d in the length of diagonal Od; (b) the change in the angle between diagonal Od and the axis; and (c) the shear strain associated with diagonals Od and cf (that is, find the decrease in angle ced).
