At 200C, the hole in an aluminum ring is 2.500 cm in diameter. You need to slip this ring over a steel shaft that has a room temperature diameter of 2.506cm. You decide that if you heat both metals maybe you could slip the aluminum ring over the steel shaft. What common temperature should you heat both metals to? (linear thermal expansion coefficient of aluminum is 2.3 x 10 ⁻⁵ K ⁻¹
