#1202-30 Linear Expansion  Apparatus, Roller Type. Determine coefficient of linear expansion of metals.  Consists of a cast iron base with rollers.  A metal tube is placed on rollers and the cast-metal end support, while steam is passed through the tube.  As the tube expands, a dial indicates rotation in degrees.  Linear value is computed by determining the length of expansion.  Instructions are provided.
