# Length Differential

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

$$\large{ \Delta l = l_f - l_i }$$
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 $$\large{ft}$$ $$\large{m}$$
