INFO 1: A block of material is machined as a cube with edge length equal to 10.000 cm at room temperature. After heating by 100 C, the block remains a cube, but with an edge length equal to 10.006 cm. INFO 2: After cooling back to room temperature, you put the block in a vise so that the dimensions along two of the dimensions cannot exceed 10.001 cm. After heating by 100 C, the unconstrained dimension of the block is 10.008 Calculate Poisson's ratio of the block, assuming that the material is elastically and thermally isotropic. Express your answer in the form y.yy (Hint: Use 2 significant figures) V = NOTE: WIRIS will provide hints if you do not correctly answer the problem. These hints are repeated below for convenience. HINT 1: INFO 1 provides enough information to calculate the coefficient of thermal expansion. HINT 2: INFO 2 provides the dimensions of the block before and after heating. Use this info to calculate the numerical values of strains epsilon 11, epsilon_22, and epsilon 33 after the block is heated in the vise. Now write that strain_11 = strain_11(elastic) + strain 11(thermal). strain_11(elastic) can be written in terms of siama 11 siama 22, INFO 1: A block of material is machined as a cube with edge length equal to 10.000 cm at room temperature.
