The formula to calculate the thermal expansion is:
\[ \Delta L = \alpha \times L \times \Delta T \]
Where:
Thermal expansion is defined as the total increase in length or dimension due to an increase in the temperature of the material.
Example 1:
Step 1: Calculate the change in length:
\[ \Delta L = 0.000012 \times 2 \times 50 = 0.0012 \text{ meters} \]
Example 2:
Step 1: Calculate the change in length:
\[ \Delta L = 0.000015 \times 3 \times 100 = 0.0045 \text{ meters} \]
