Length Differential

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

 

Length Differential formula
\(\large{ \Delta l = l_f - l_i }\)
Symbol	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	\(\large{ft}\)	\(\large{m}\)
