... as stability and reliability are met. Objective: The aim of the tests was to observe change in length of certain metals and correspondingly determine the coefficient of linear expansion and how each metal reacts differently to temperature changes. Procedure: Four rods of a measured length were each separately put into a steam generator connected to an extensometer and a thermometer. Starting from room temperature, the expansion and temperature was recorded every 10s for the first 10 minutes. After each rod, the apparatus is disassembled and allowed to cool before next metal is tested. Results: The 4 metals tested were Copper, Brass, and Stainless Steel.
