THERMAL EXPANSION CALCULATOR


Thermal Expansion Calculator to calculate linear thermal expansion of an unrestrained bar when the temperature of the bar is uniformly changed. Linear thermal expansion formulas which are used for calculations are given in the "List of Equations" section.

If the temperature of a bar , which rests freely on a surface, is increased by ∆T, the bar expands linearly by an amount of δT. The amount of elongation is proportional to the temperature change ∆T, the length of the bar L and coefficient of thermal expansion of bar material α.
