THERMAL EXPANSION CALCULATOR
Thermal Expansion Calculator has been developed to calculate
linear thermal expansion of an unrestrained bar when the temperature of the bar is uniformly changed. 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 δ_{T}.
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.
