Learning Goal:
To determine the elongations and contractions in a
rectangular prismatic member that is subjected to stresses
in the x and y directions.
The member shown is subjected to a compressive stress in
the x direction of $\sigma_x = 325$ ksi and a compressive stress in
the y direction of $\sigma_y = 650$ ksi. The dimensions of the
member are a = 4.25 in, b = 1.00 in, and t = 0.75 in.
Assume that E = 29000 ksi and that Poisson's ratio is $\nu =$
0.32.(Figure 1)
Determine the normal strain in the x direction, $\epsilon_x$.

Part D - Change in dimension of the member
The applied stresses cause the member to experience a change in all of its dimensions. What are the new dimensions, a', b', and t', of the member due to the applied stresses?
Express your answers in inches to three significant figures separated by commas.
