SUMMARY
The discussion centers on calculating the temperature required for an iron rod with a diameter of 2.50 cm at 20.0° to fit into a ring with an inside diameter of 2.51 cm. The coefficient of linear expansion (alpha) is given as 1.0 x 10^-5. The formula for linear expansion, ΔL = (alpha)(L)(ΔT), is applicable, where L is the original length (or diameter in this case) and ΔT is the change in temperature. The diameter of the rod will expand similarly to its length, confirming that the same principles of thermal expansion apply.
