A plastic bar fits snugly between rigid supports at room temperature (68°F) but with no initial stress (see figure). When the temperature of the bar is raised to 160°F, the compressive stress on an inclined plane pq becomes 700 psi. What is the shear stress on plane pq? (Assume a = 30 x 10-6°F and E = 450 x 10 psi.) Figure 4
