A copper rod and a steel rod are heated. At 0 ◦C the copper rod has a length of LC, the steel one has a length of LS. When the rods are being heated or cooled, a difference of 5.73 cm is maintained between their lengths. If αC = 1.7 × 10−5 ( ◦C)−1 and αS = 1.2 × 10−5 ( ◦C)−1 , 1) Find the value of Lc. 2) Find the value of Ls. Answer in units of cm.

    You want to insert an aluminum rod, which at 20°C has a radius of 1.00020 cm into a copper tube which has a radius of 1.00010 cm at the same temperature. You decide to put both of them in the refrigerator. At what temperature will the rod just fit if both are cooled to the same temperature? The coefficient of thermal expansion for aluminum is 2.4 × 10-5 K-1, and that of copper is 1.7 × 10-5 K-1.

    A copper rod and an aluminum rod of the same length and cross-sectional area are attached end to end (Figure 1). The copper end is placed in a furnace maintained at a constant temperature TCu = 230 ∘C . The aluminum end is placed in an ice bath held at a constant temperature of 0.0∘C. Calculate the temperature at the point where the two rods are joined.

    Original Temp = 22 degrees C 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...
