Final answer:
The answer to the student's question is (c) Shrink-fit Pressure and Von Mises Stress, where shrink-fit pressure refers to the pressure between shrink-fitted parts and von Mises stress is the stress criterion for assessing material yield.
Step-by-step explanation:
For components that are shrink-fitted together, the nominal shrink-fit pressure is the pressure present between the two fitted parts due to the interference between them, and the von Mises stress is a theoretical yield criterion that represents the state of stress at any point within a material that allows the assessment of the likelihood that the material will yield at that point.
Therefore, the correct answer to the question 'For components shrink-fitted together, what is the nominal shrink-fit pressure, and what is the von Mises stress in each body at the fit surface?' would be (c) Shrink-fit Pressure and Von Mises Stress.
Shrink-fit pressure can be calculated based on the interference level, material properties, and geometry of the components. On the other hand, the von Mises stress is determined using the distortion energy theory, which states that yielding begins when the distortion energy per unit volume reaches the same level as the distortion energy per unit volume for yielding in a tensile test.
