It is NOT any sort of animal. If steel SIMPLY shrinks when it cools is a fact then the heavier work must also shrink when it cools. The material facing this tensile stress can get a hot-crack during welding, or can cold crack during service if these residual stresses are not relieved. The aluminum will expand (3X) whle the steel will less (2x) and the bearing should come out. Suggestion to take out "percentage".Also, the table should list all numbers in the same format (i.e., you have "0.00000234", "16.9 ppm", "4.5 x 10(-5)", and also show (sometimes) the units in the table, even including C for a table that everything else is in F. The units are already given in the column header, so suggestion to take out units, convert those that are in C to F, and format all numbers to be in a single format. For example if steel has a thermal expansion coefficient of 11.710-6 1/C it means that a 1 m long bar subject to a temperature increase of 1C will expand 11.710-6 m, or 0.0117 mm. To determine the thermal expansion coefficient, two physical quantities (displacement and temperature) must be measured on a sample that is undergoing a thermal cycle. In fact, it contracts. The CTE employs reciprocal temperature units (K-1, F-1, C-1, etc.) Its high expansion should be considered when aluminum is used with other materials, especially in rigid structures, although the stresses developed are moderated by the low elastic modulus of aluminum.
