# 2-12. Normal Strain in rods constrained by walls with misfitRods (1) and (2) were supposed to fit exactly between the rigid walls at A and C, as indicated in the figure below. However, rod(2) was manufactured a small amount, 8L, too long. A technician decides to lower the temperature of rod (2) by AT so thathe can insert it in the space between B and C. When rod (2) returns to its initial temperature, the length of each rod is no longerthe same as the original one, and the resulting strain is often called "residual strain"".Rod (1) has Young modulus E₁ = 74 GPa and cross-sectional area A = 1749 mm². Rod (2) has Young modulusE₂ = 204 GPa and same cross-sectional area A. Both rods have length L = 738 mm.LL(1)€ =E₁,α₁, ABEz az.

# 2-14. Normal Strain in rods constrained by walls with misfit At its initial temperature, the bar is too long by a distance of 8 to fit into the gap between the rigid walls, which are separated by a distance L. In order to make it fit tightly, the bar is cooled to a very low temperature so that it shrinks enough to fit easily into the gap. After it is fit in the gap, the temperature of the bar is raised to a temperature AT below the initial temperature and the bar fits tight between the walls. What is the stress in the bar at this temperature AT? The bar has elastic modulus E = 35. 10³ ksi, thermal expansion coefficient a = 6.10-6 /°F and cross-sectional area A = 1 in².
