Elongation of a bar under self weight

(Strength of Materials – by Er. R.K. Rajput)

δl: elongation of the bar

l: length of the bar

ρ: density of the bar

E: Modulus of elasticity of the bar

elongation under self weight is an important parameter to be calculated when the bar is subjected to vibration analysis so that the appropriate stiffness of the damper and the spring can be calculated and can be included in the system to maintain the equilibrium under the application of the external forces. As a result, the structural damages can be minimized.
