Length Differential

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Length differential, abbreviated as \(\Delta l\), is the difference between an expanded or reduced length of an object.


Length Differential formula

\(\large{ \Delta l = l_f - l_i }\)


 Units English Metric
\(\large{ \Delta l }\) = length differential \(\large{ft}\) \(\large{m}\)
\(\large{ l_f }\) = final length \(\large{ft}\) \(\large{m}\)
\(\large{ l_i }\) = initial length \(\large{ft}\) \(\large{m}\)

\(\large{ \Delta T }\) = temperature differential

\(\large{ \alpha }\)  (Greel symbol alpha) = thermal expansion coefficient
