The Thermal Expansion Calculator will calculate the:
Thermal Expansion Calculator Restrictions: The material is taken as homogenous.
|The linear expansion or contraction of a bar of original length L0 is m|
|The area expansion or contraction of a thin plate of original area A0 is m2|
|The volume expansion or contraction of a thin plate of original area V0 is m3|
|Final length of the bar calculations|
|L = L0 × 1 + α × ( T - T0 )|
L = × 1 + × ( - )
L = × 1 + ×
L = ×
|Final area of the plate calculations|
|A = A0 × 1 + 2α × ( T - T0 )|
A = × 1 + (2 × ) × ( - )
A = × 1 + ×
A = ×
|Final volume of the object calculations|
|V = V0 × 1 + 3α × ( T - T0 )|
V = × 1 + (3 × ) × ( - )
V = × 1 + ×
V = ×
|Thermal Expansion Calculator Input Values|
|Original length of the bar (L0) =|
|Original Area of the thin plate (A0) = m2|
|Original Volume of the solid object (V0) = m3|
|Linear expansion coefficient of the material (α) = K-1|
|Initial temperature of object (T0) = °C|
|Final temperature of object (T) = °C|
Please note that the formula for each calculation along with detailed calculations are available below. As you enter the specific factors of each thermal expansion calculation, the Thermal Expansion Calculator will automatically calculate the results and update the Physics formula elements with each element of the thermal expansion calculation. You can then email or print this thermal expansion calculation as required for later use.

Remark! You can find the amount of expansion or contraction Δ in each case by subtracting the original value from the final one. Thus,
If Δ > 0 , there is thermal expansion and if Δ < 0 , there is thermal contraction in the material.
