Elongation of a bar due to its own weight:

λ is specific weight or unit weight of the material (Weight per unit volume), N/m3
Wx = Weight of portion below the section = λ × Ax
Stress on the element, dx = Wx/A = λx
Strain in the element, ϵ = Stress/E = λx/E
Elongation of the element, δLx = Strain × Length of Element

Total elongation:

If W is total weight of the bar, W = λ × AL
