Initial Length

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Formulas that use Initial Length

\(\large{ l_i =  \frac{ l_f }{ \alpha_l  \; \left( T_f \;- \; T_i \right) + 1 }  }\)  (linear thermal expansion coefficient
\(\large{ l_i = \frac{ \Delta l }{ \epsilon }  }\)  (strain)

Where:

\(\large{ l_i }\) = initial length

\(\large{ l_f }\) = final length

\(\large{ \Delta l }\) = length differential

\(\large{ \alpha_l }\)   (Greek symbol alpha) = linear thermal expansion coefficient

\(\large{ \epsilon }\)  (Greek symbol epsilon) = strain

\(\large{ T_f }\) = final temperature

\(\large{ T_i }\) = initial temperature
