Multiple-Concept Example 4 illustrates the concepts that are pertinent to this problem. A cylindrical brass rod (cross-sectional area 5 1.3 × 10-5 m2) hangs vertically straight down from a ceiling. When an 860-N block is hung from the lower end of the rod, the rod stretches. The rod is then cooled such that it contracts to its original length. By how many degrees must the temperature be lowered? |
