A steel ring with a hole having area of 8.970 cm is to be placed on an aluminum rod with cross-sectional area of 9.000 cm. Both rod and ring are initially at a temperature of 22.0C. At what common temperature can the steel ring be slipped onto one end of the aluminum rod? (The coefficient of linear expansion of steel is11 10-6 (C) -1, and the coefficient of linear expansion of aluminum is 24 10-6 (C) -.) C
