Length differential, abbreviated as \(\Delta l\), is the difference between an expanded or reduced length of an object.
Length Differential Formula |
||
| \( \Delta l = l_f - l_i \) | ||
| Symbol | English | Metric |
| \( \Delta l \) = length differential | \(ft\) | \(m\) |
| \( l_f \) = final length | \(ft\) | \(m\) |
| \( l_i \) = initial length | \(ft\) | \(m\) |
