Length Differential

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

 

Length Differential formula
\( \Delta l = l_f - l_i \)
Symbol	English	Metric
\( \Delta l \) = length differential	\(ft\)	\(m\)
\( l_f \) = final length	\(ft\)	\(m\)
\( l_i \) = initial length	\(ft\)	\(m\)
