Strain

Strain

Strain is the deformation, stretched or compressed, of a material compared to its original length.

Strain formula

\(\large{ \epsilon = \frac{ l_c }{ l }  }\)

Where:

\(\large{ \epsilon }\)  (Greek symbol epsilon) = strain

\(\large{ l }\) = length

\(\large{ l_c }\) = change in length

Solve for:

\(\large{ l_c = \epsilon {l} }\)

\(\large{ l = \frac{ l_c }{ \epsilon}  }\)
