A cylindrical pin of diameter 20 cm, made of aluminum, does not fit through a 19.97cm circular hole in a copper plate. The pin and the copper plate both are initially at a temperature of 110 degrees C. At what temperature, in degrees C, does the cylindrical pin just fit into the circular hole of the copper plate if both the plate and the pin are cooled together?

At 20∘C, the hole in an aluminum ring is 2.200 cm in diameter. You need to slip this ring over a steel shaft that has a room-temperature diameter of 2.204 cm . To what common temperature should the ring and the shaft be heated so that the ring will just fit onto the shaft? Coefficients of linear thermal expansion of steel and aluminum are 12×10-6K-1 and 23×10-6K-1 respectively. Express your answer in degrees Celsius to two significant figures.
