The actual length of the line 469.449 ft, if one assumes the modulus of elasticity of steel to be 29,000,000 psi.
A metal's elasticity is defined as the rate at which a specific metal sample can change in size and shape in response to a variety of stress and strain forces as well as other externally varying factors. The measured level of ductility of a metal can also be referred to as elasticity.
Due to the increased surface area that is exposed when elongated, metals that are subjected to repeated applications of force to cause elastic expansion are more vulnerable to stress corrosion, cracking, and crevice corrosion.
When a metal deforms elastically, the process is reversible, allowing the metal to revert to its initial shape.
