Question

Question: The sketch represents a thin ring of aluminum shrunk onto a disk of steel, the contact pressure is p_c = 8.0MPA at 20 C, to what temperature will the entire assembly be raised to loosen the ring?

Answer (for reference): Delta(T) = 107.2 C

The sketch represents a thin ring of aluminum shrank onto a disk the contact pressure is p_c = 8.0 MPa at 20 degree C, to what temperature assembly be raised to loosen the ring? E_st = 200 GPa alpha_st = 12(10)^-6/degree C E_AI = 70 GPa alpha_AI = 24(10)^-6/degree

Explanation / Answer

Delta(T) = 107.2 C
