Linear Thermal Expansion of a Meter Stick

  1. Nov 10, 2015 #1

    If a thermal linear expansion happens to a meter stick, for instance a 50 m steel meter stick, the new length would be 50(1+(coefficient of expansion )(ΔT)). My question is would this also work if we choose different segment of the meter stick?For example, Can the new length for the part from 0 to 10m of the meter stick be shown by 10(1+(coefficient of expansion )(ΔT))?

    (I assume you meant 0-10cm)

    Yes, thermal expansion is a fraction of initial length, regardless of what segment you are looking at.

    He has a 50 meters long "meter stick". :wink:
