摘要:

The static elongation of a loaded spring is derived taking into account its own weight and the fact that a finite nonzero force is required to pull the spring apart. A simple experiment is described to verify that the static effective mass is equal to half of the total mass of the spring using a slinky. The experimental result is in good agreement with the theory.
