Final Length

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Final Length formula

\(\large{ l_f =  \overrightarrow{\alpha_l} \; l_i  \; \left( T_f \;- \; T_i \right) + l_i   }\)  (linear thermal expansion coefficient

Where:

 Units English Metric
\(\large{ l_f }\) = final length \(\large{ft}\) \(\large{m}\)
\(\large{ l_i }\) = initial length \(\large{ft}\) \(\large{m}\)
\(\large{ \overrightarrow{\alpha_l} }\)   (Greek symbol alpha) = linear thermal expansion coefficient \(\large{ \frac{in}{in\;F} }\) \(\large{ \frac{mm}{mm\;C} }\)
\(\large{ T_f }\) = final temperature \(\large{F}\) \(\large{C}\)
\(\large{ T_i }\) = initial temperature \(\large{F}\) \(\large{C}\)
