tension strength 6Elongation, abbreviated as E, is the increase in length to which a material is to be stretched prior to rupture.


Elongation Formula

\(\large{ E = \frac{ F_a \; l_i }{ A_c \; \lambda}  }\) 
Symbol English Metric
\(\large{ E }\) = elongation \(\large{in}\)  \(\large{mm}\) 
\(\large{ F_a }\) = applied force \(\large{lbf}\) \(\large{N}\)
\(\large{ A_c }\) = area cross-section \(\large{ft^2}\) \(\large{m^2}\)
\(\large{ \lambda }\)  (Greek symbol lambda) = elastic modulus \(\large{\frac{lbf}{in^2}}\) \(\large{Pa}\)
\(\large{ l_i }\) = initial length \(\large{ft}\) \(\large{m}\)
