Extracted text: 3.117 The prismatic bar has a cross-sectional area A = 3 in? and is made of material with modulus of elasticity E = 28E6 psi and coefficient of thermal expansion 8E-6 F-. It is constrained between rigid walls. The temperature is increased by 50 °F above the bar's initial temperature T, and a 20,000-lb axial force to the right is applied midway between the two walls. What is the normal stress on a plane perpendicular to the bar's axis to the right of the point where the force is applied? a =
