A ring made from aluminum has an inner radius of 2.50000 cm and an outer radius of 3.50000 cm, giving the ring a thickness of 1.00000 cm. The thermal expansion coefficient of aluminum is 23.0 ⨯ 10-6/°C. If the temperature of the ring is increased from 20.0°C to 90.0°C, by how much does the thickness of the ring change?

A 21.0 g copper ring at 0°C has an inner diameter of D = 2.50458 cm. A hollow aluminum sphere at 91.0°C has a diameter of d = 2.50922 cm. The sphere is placed on top of the ring (see the figure), and the two are allowed to come to thermal equilibrium, with no heat lost to the surroundings. The sphere just passes through the ring at the equilibrium temperature. What is the mass of the sphere? The linear expansion...

At 20∘C, the hole in an aluminum ring is 2.700 cm in diameter. You need to slip this ring over a steel shaft that has a room-temperature diameter of 2.707 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 12×10−6 K−1 and 23×10−6 K−1 respectively.

3. An aluminum ring has an inner diameter slightly smaller than the diameter of a steel rod. The aluminum ring is heated so that it expands sufficiently to fit over the steel rod and cooled so that it makes a tight fit. Because aluminum expands and contracts at a greater rate than steel, the system should be heated. The diameter of steel rod is 4.040 cm and the diameter of the aluminum ring is...
