Tension Change in Length formulas

\( \Delta d = d_i - d_f  \) 

\( \Delta d =  \epsilon_{di} \; d_i  \) 

\( \Delta d =  ( \mu \; \sigma \;/\; \lambda ) \; d_i  \) 

\( \Delta d =  ( \mu \; p \;/\; \lambda \; A ) \; d_i  \) 

\( \Delta l =  l_f - l_i  \)

\( \Delta l =  \lambda \; l_i  \)

\( \Delta l =  ( \sigma \;/\; \lambda ) \; l_i  \) 

\( \Delta l =  ( p \;/\; \lambda \; A ) \; l_i  \) 

Symbol English Metric
\( A \) = area \( in^2 \) \( mm^2 \)
\( d_f \) = final depth \( in \) \( mm \)
\( d_i \) = initial depth \( in \) \( mm \)
\( \Delta d \) = depth change \( in \) \( mm \)
\( \lambda \)  (Greek symbol lambda) = elastic modulus \(lbf\;/\;in^2\) \(Pa\)
\( l_f \) = final length \( in \) \( mm \)
\( \Delta l \) = length change \( in \) \( mm \)
\( l \) = length under consideration \( in \) \( mm \)
\( \mu \)  (Greek symbol mu) = Poisson's Ratio \( dimensionless \)
\( p \) = pressure under consideration \(lbf\;/\;in^2\) \(Pa\)
\( \epsilon \)  (Greek symbol epsilon) = strain \(in\;/\;in\) \(mm\;/\;mm\)
\( \sigma \)  (Greek symbol sigma) = stress \(lbf\;/\;in^2\) \(Pa\)
\( \sigma_t \)  (Greek symbol sigma) = tensile stress \(lbf\;/\;in^2\) \(Pa\)
